Kim’s Tips for Rooting Your Own Lavender Cuttings

How wonderful—the fragrance of lavender wafting through the back yard. You’re pleased beyond measure with these silver-leaved subshrubs in the pollinator garden, and perhaps you’d like more of them. The bees and butterflies are all over them! And the deer never touch them!! Garden centers stock several cultivars of lavender, but they are not inexpensive. Problem solved: “I’ll root my own lavender cuttings!”

The plants have performed well, and the garden is buzzing with activity. Now, you’d like to expand the garden to provide even more sustenance for all the bees and other insects. Admittedly, there is some work involved. Properly preparing the heavy clay soil takes effort and materials, but you know it will be worthwhile.

We need pollinators for farms and orchards, for our own vegetable gardens, and to regenerate natural stands of greenery. They pollinate every third bite of food we eat.

Because it takes several weeks to root cuttings and to grow them on to the proper size for transplanting, time is on your side. So, let’s begin by taking cuttings from the plants in the garden. While they’re rooting, you’ll have plenty of time to get the soil just right for the new plants.

 

Patent Rights

Because it’s illegal to propagate trademarked plants for resale, I bought the newer lavender cultivars in trays of 60 to 200 tiny rooted plants, called plugs. Labels of branded varieties carry the caution, “Unauthorized propagation prohibited”. Many varieties were not under patent protection, however, so those were the ones I propagated.

 

Lavender from Seed

Another option is sowing seeds—‘Ellagance Purple’ and ‘Lady’ are two that you might try growing. ‘Munstead’ is a strain that has been around for a long time. Seeds take a few weeks to germinate, so this project is best started in spring. Plants grown from seed (sexual propagation) can vary in certain characteristics, including plant size, foliage color, flower color and size, and time to first bloom.

Plants vegetatively propagated, on the other hand, will have consistently similar characteristics. Cloned plants, from cuttings, have the same genetics as the stock plant, so the rooted cuttings will look identical to the parent.

Prepare the Pots and Soil for Lavender Cuttings

 

First, assemble 4″ or 4 1/2″ plastic pots. Bigger pots hold a much larger volume of soil and dry too slowly.

Lavender is susceptible to several fungal diseases, so starting with clean materials is essential. At the very least, wash the pots with soap and hot water. Better yet, clean the pots with a bleach solution, let them sit for a few minutes, then rinse thoroughly.

Another option is to use new cell packs, with 4 to 9 cells per pack. Soil in small cells dries faster, so you’ll need to closely monitor these containers.

Don’t use soil left over from last year’s plants; it could be harboring disease spores. Never throw “used” soil into the trash. Instead, add it to the flower gardens or the shrub border, where it will contribute organic matter as it decomposes.

 

Options for Potting Soil:

  • Always begin with pasteurized potting soil. Mix this with clean coarse sand or perlite. The medium should drain well, allowing both water and air to percolate through the soil.
  • Use products formulated for succulents, and add houseplant potting soil to make a gritty medium, but one which will hold some water.
  • Or, simply, use a fresh bag of pasteurized potting soil, which includes perlite, and be very careful about watering.

Avoid using soil containing a large percentage of peat moss, which is acidic and stays too wet for lavender. This herb, like many others, needs close to a neutral pH.

Incidentally, most potting soils sold in garden centers contain no soil at all, and are sometimes called “soilless potting mixtures”. For our purposes, the term “potting soil” will do.

If the medium is dusty dry, mix in a small amount of water. Avoid breathing in the dust. The soil should be slightly damp. Fill the pots with potting soil, and firm lightly. Leave about 1/2″ to 1″ of space between the soil surface and the pot’s rim.

 

 

Making the Cut

When To Cut

Cuttings taken in early to mid summer should root adequately before autumn. These are considered “semi hardwood” cuttings. The stems aren’t fully matured, but they aren’t too tender, either. Tough old woody stems will not root.

Collect lavender cuttings in the morning, when they’re fully plumped with water. Don’t use material from the bottom or from the shady side of the plant. Use healthy foliage, without any spots. Cuttings from plants that have not been overfertilized with nitrogen are more likely to root successfully.

 

How To Take Lavender Cuttings

With clean sharp scissors, take cuttings from non-blooming, non-budded stems. Lavender cuttings from the tips of the stems, rather than from middle sections, make better propagating material. If your early blooming lavender plants were deadheaded (old flower stems cut back) early in the season, the remaining stems might already have branched out, providing fresh cutting material.

Cuttings, before removing bottom leaves.

 

Lavender cuttings should be only 2″ to 3 1/2″ long, depending on variety. Large cuttings have greater leaf surface area, and the cuttings might wither before roots form. When taking cuttings from any plant, consider the number of leaves, light, water, humidity, and time to root. Each variety has its own combination of variables that results in prompt, successful rooting. Long cuttings, low humidity, lack of light, and wet or dry soil will not yield rooted plants.

Make the cut where two leaves join the stem (photo at top). This part of the stem is called the “node”, and the first roots often emerge there.

Now, remove leaves on the bottom inch or so of the stem. Gently peel them off. Otherwise, leaves will rot in the soil, which could rot the stem.

Rooting Lavender Cuttings In Water

Coleus cuttings start rooting in water in a few days; lavender requires weeks in soil. When possible, I always root plants in potting soil rather than in water. The roots’ cell structures differ between the two methods, and those growing in water often die when re-adapting to soil.

If you have plenty of cuttings, perhaps rooting some in water will work for you. Cuttings should still be about 3 1/2″ long. Use only an inch of water in a glass, don’t crowd the cuttings, and remove leaves in the water. Place the glass in part sun, and change the water every few days.

 

 

Sticking the Lavender Cuttings

 

After decades of rooting plants under lights for my business, I’ve had the most success with cuttings that were stuck right next to the inside of the pot. Particles of soil touching the wall of the pot tend to permit more air to circulate around the stems. That’s precisely what lavender needs.

The stems aren’t sitting in wet soil, although there is some contact. At night, as the temperature drops, water vapor precipitates on the inside of the pot. And the humid air in that space helps the cuttings root.

This 4 1/2″ pot accepted 9 cuttings, with 1 in the center. Avoid crowding the cuttings; space them so their leaves don’t touch each other. Lightly water in the cuttings to make better contact between the stems and the soil.

I propagate other herbs, including thyme, rosemary, oregano, sage, and bay laurel, in the same way.

 

Actinovate

When propagating herbs and perennials each season, I use an organic biological fungicide called Actinovate. This product, a bacterium called Streptomyces lydicus strain WYEC 108, prevents vulnerable plants from succumbing to most diseases. Water the solution into the soil after sticking or lightly mist the cuttings, occasionally, in the morning. I also use it when germinating seeds.

This fungicide is quite expensive, but it makes plant propagation much easier for me. It carries the OMRI label and is safe to use on edibles.

Always exercise caution when using materials for treating plants. Don’t breathe the dust, avoid getting it on your skin (rinse thoroughly), and don’t improperly dispose of leftover product or the container. Read the label.

 

Rooting Hormone

Rooting hormone powder coats the base of the cutting with a chemical fungicide and plant hormones. While it accelerates the rooting process for many plants, this product carries the Environmental Protection Agency’s Caution rating, as does Actinovate.

I haven’t used it for many years, but, if you’ve had good results using rooting powder, then try it on your lavender cuttings. Always read the label, and never discard leftover powder where it can pollute streams.

 

 

Raise the Humidity

To raise the humidity around the cuttings without causing rot, place the pot of cuttings into a clear plastic bag. Pull up the bag so it surrounds the cuttings, but don’t secure it. Fuzzy-leaved plants, such as lavender, rot (not “root”) easily in high humidity. A closed plastic bag or some other closed system raises the relative humidity to 100%. It also causes the “greenhouse effect”, raising the temperature too high when exposed to the sun.

So, keep the top of the bag open. Enough humidity will remain around the lavender cuttings. In very dry environments, the bag can be partially closed, but don’t let heat build up. Empty any water that collects at the bottom. If the soil is moist and there’s significant condensation inside the bag, open the top more widely, and let excess moisture dissipate. Wet soil will rot the cuttings.

 

 

Light For Lavender Cuttings

Lavender loves to bask in the sunshine. The sooner the cuttings get back to the sun, the sooner they can resume strong growth. But harsh sun will desiccate the unrooted cuttings. This is a race against time.

 

Indoors

Indoors, place the cuttings where they will get gentle direct sunlight. Sunlight helps cuttings root faster, but strong sun will dry them and overheat the air inside the bag. Bright filtered sun most of the day, as through a sheer curtain, works well. Average indoor temperatures (high 60’s F to the mid 70’s) will help them root.

Don’t put the cuttings too close to a window, in the hot sun. Check to make sure excess heat can escape. Lavender cuttings will not root in low light, so it might require a bit of experimentation to find the perfect light level to root the cuttings without desiccating them.

New growth emerging from the tip of the stem indicates a cutting that is beginning to root. Congratulations! Patience pays off!

 

Artificial Light

A 4′ long fixture with 2 daylight LED or fluorescent tubes makes a perfect nursery. Here, the plants never see a cloudy day, and you can keep a close eye on progress.

Place the lavender cuttings close to the tubes, within 3″. They should be as close as possible to the lights, but not feel heat from the fixture. Keep the lights on for 16-18 hours each day.

Smaller tubes and grow bulbs emit less light, which might not be enough for lavender. But if that’s what you have, try it. Make sure the cuttings are close to the tubes and that the lights are kept on for 18 hours each day.

 

Outdoors

Many of us don’t have indoor space suitable for rooting lavender cuttings. In that case, place the pots outdoors in dappled shade when the temperature is suitable. Give them more bright shade than harsh sun. Don’t expose them to hot afternoon sun and find a location out of the wind.

In a pinch, take a few cuttings and simply stick them at the edge of a planter, in light shade cast by a plant. I’ve been able to root many kinds of plants this way. Watch out for slugs, by the way, and use organic Sluggo to bait them. Scoop out rooted plants, and pot up for a few additional weeks of growing and getting used to full sun before planting them in the garden.

The cuttings in the photographs go outdoors on the deck in the morning. I take them back inside at noon or in early afternoon. It’s been way too hot and humid outside this summer—mid 90’s F, over 100° heat index for days at a time. When it cools down, they’ll spend more time outdoors.

(***Update***: The pot of cuttings in the photographs has only one survivor. Prolonged heat, frequent downpours, and mischievous chipmunks digging in the soil killed the rest. But that one well-rooted plant looks great, and will stay in its 4″ pot over the winter. 1/1/2021)

 

 

Ready for Transplant?

 

Okay…it’s been about 5 or 6 weeks and most of the cuttings show new leaves growing at the tips of the stems. That’s great!

If you see roots at the drainage holes in the bottom of the pot, the cuttings might be ready to divide. Remove the cuttings from the pot by gently tipping the pot upside-down. See if there are enough roots to move them to the next stage. Each cutting should have a few 1″ to 2″ long roots. Handle with care, since the roots detach easily from the stems and dry quickly when exposed to air.

 

Cuttings Rooted in Pots

Before settling them into their permanent homes, the rooted cuttings in pots will need to grow a more extensive root system. Transplant them individually into their own small pot or into 4-cell market packs. Be sure to maintain the same soil level against the stem; never bury the stems. Use the same kind of soil you used to root them.

If they’re rooted, give them a few hours of direct sun for a few days before exposing them to full sun. Let them root into the pots before planting in the garden. Rooted cuttings don’t require high humidity, so remove the plastic bag.

 

Cuttings Rooted in Cell Packs

If you planted the cuttings in market packs to begin with, simply push up the bottom of a cell to check root growth. Don’t pull the cutting itself. Well-rooted plants can be planted directly into the garden if you monitor them very closely. If needed, cover temporarily with a “caterpillar” tunnel fitted with bird netting. This protection admits air and sunlight, and will prevent damage from digging animals while the lavender becomes established.

If cold weather is approaching, use a clear plastic cover over the tunnel, and vent it in the daytime. This will buffer severe conditions, and could save the plants.

 

Harden Off the Lavender Cuttings

Harden off the cuttings by gradually introducing them to outdoor conditions over a period of a week or so. Place the pots of lavender outdoors, in morning sun for a few days, then in more hours of sun. It’s easy to forget them, when they’re out of sight, so remember to water! Plants receiving abundant sunshine make more food for themselves, through photosynthesis, so their roots will grow faster. By the end of the hardening off process, the plants should be able to tolerate direct sun all day.

Remove flower buds appearing on young cuttings. For now, all energy should be directed toward growing a robust root system.

Any cuttings that haven’t rooted and have foliage that feels limp can be discarded. If they look like this after a month, it’s not likely they will root. Figure out how to improve the growing conditions, and try again.

 

 

The Garden is Ready

And so are the plants. Water them first. Then remove the rooted plant from its pot and gently loosen the outer roots if they form a tight root ball.

Plant the little lavenders, maintaining the same soil level next to the stem. Firm the soil around the roots to eliminate air pockets. For almost all plants, you should be able to see the top of the original root ball after transplanting.

Be sure to space them properly, according to the variety. Some mature at 16″ tall and wide, while others can grow as large as 3′ or 4′ across. Lightly shade the plants if the leaves wilt in moist soil. Sticking a leafy twig in the ground on the sunny side works well enough.

During hot weather, check the soil moisture every day, although you might not have to water every day. Feel the soil a few inches down and next to the root ball. If you detect moisture, don’t water. If it wilts or the soil feels dry, water around the root ball.

When you do water, keep the foliage dry. This helps prevent disease.

 

To Mulch Or Not To Mulch

If you use mulch in the garden, avoid placing it under the canopy of the plant. Where it rains regularly, mulch can hold too much moisture in the soil, so use only a thin layer or, preferably, none at all right under the plant. Keep mulch off the stems.

Avoid finely shredded hardwood mulches, and choose pine fines or small nuggets instead. They permit better air circulation around the lavender.

Planting lavender on raised ground helps the soil drain faster, and plants display better when elevated above surrounding lawn or paving.

 

Is Your Lavender Winter Hardy?

Each plant variety has a hardiness zone rating, usually between zone 5 and zone 9 for lavender. If you live at the colder end of that variety’s hardiness zone, the rooted plants might need the protection of a cool greenhouse or a cold frame until next spring. It depends on expected weather patterns—temperature and precipitation—over the next several months for the cultivars you’ve selected.

At this point, in late summer, waiting to propagate lavender until next year might be more feasible, especially for gardeners in colder climates.

Lavender is drought resistant once established in the garden, but often dies when overwatered. Improving soil drainage is especially important for cultivars planted in the colder regions of their hardiness zones. “Winter wet” is a frequent cause of lavender failure.

Plant lavender with other perennials and shrubs that share its preferred growing conditions. Although it isn’t native to the U.S., it is non-invasive.

Better for the Environment

Traditional property management calls for removing winter shelter and sources of food for insects and animals, so this is how we can begin to compensate, right in our own gardens.

Propagating plants is an economical means of providing new material for your gardens. Planting species that offer sustenance to pollinators is not only ecologically preferable to maintaining lawn grass, but it’s also prettier!

Bees and Butterflies: At Home In Your Garden

 

National Pollinator Week: June 22-28, 2020

 

lavender, for bees and butterflies

Lavender and honey bees.

 

In 2007, the U.S. Senate passed a bill designating one week in June as National Pollinator Week. This legislation recognizes the importance of pollinators, including bees and butterflies, in our food supply and in the health of all ecosystems.

Every third bite of food we consume is directly attributable to pollinators. The global economic value is worth between $300 billion and $600 billion per year. Around 85% of all flowering plants are pollinated by insects, ensuring the regeneration of forests and fields as well as high yielding edible crops.

Our morning coffee beans are primarily self-pollinated, depending on crop species. Introducing bees, however, can increase the yields and lower costs of production.

In tropical regions of South America, Africa, Indonesia, and, more recently Australia, a tiny midge is responsible for pollinating cacao trees, bringing us chocolate. Chocolate contributes, incredibly, $100 billion annually to the global economy.

In the southern hemisphere, pollinator awareness programs take place in November. The Australian Government’s Department of the Environment recognizes November 8-15 as their pollinator week for 2020. Many countries throughout the world observe this initiative, and local organizations sponsor programs to raise awareness.

An outdoor project can be an enjoyable and healthy way to use our time. Having the children participate will teach them valuable skills they will carry with them wherever they live.

 

And, if there’s one thing we could use more of, it’s nature.

What Bees and Butterflies Need

 

All living creatures need food and water, shelter, and a place to raise their young. By adapting the way we maintain the property around our homes, we can achieve both an attractive landscape and one that fosters populations of wild creatures. Currently, 40% of the insect pollinator species are at risk of extinction. A few of us can make a small difference in our neighborhood; millions of us can really shake it up!

Houses—entire communities—generally have been built after felling all the native trees, bulldozing the rest, and covering the ground with a high maintenance lawn. Streams were diverted to concrete pipes underground, taking habitat from frogs, salamanders, and turtles. Where this tradition is changing, developers are roping off and protecting native stands of trees and understory species.

Maybe the builder spotted in a fast growing silver maple, a row of clipped hollies along the foundation, and a couple of forsythias in the back. Well, that won’t do much for all the bees and butterflies, or for the hummingbirds, bats, moths, and beetles that pollinate our crops and wild plants. And right there, in this yard and in that yard, lie the broken links in the food chain. Our monocultured and unnaturally manicured properties are sold as low maintenance, but there’s little life there.

 

The Missing Elements

We concentrate instead on creating an “indoor oasis”, untroubled that the quiet stillness outside the door is not what Mother Nature had intended. No birds chirping or warbling…no cicadas or katydids…no lizards leaping for their dinner…nowhere for the dragonfly to land.

Yes, we need more nature in our lives. By cultivating a relationship with the natural world, there’s more than just a pretty sight beyond the living room windows. There’s life. Birds will continue to follow million-year-old migration paths. Mason bees and swallowtail butterflies will secure homes for their young. And there will be less talk of scarcity.

1. A Garden of Annuals for Bees and Butterflies

 

marigolds for bees and butterflies

Maybe this week’s goal is to carve out a section of the big lawn in the sunny back yard, and plant a flower garden. Mid summer isn’t too late for annuals, either from seeds or from transplants. Or, for now, consider how your family can use the property in the future. It’s always a good time to decrease the amount of lawn space we have to mow, fertilize, and treat for insects and diseases.

Be sure to plant significant drifts of flowers instead of a dot of zinnias here and a couple of marigolds over there. Large blocks of similar colors are more likely to get attention from pollinators. If your space is limited, though, there are some options. Sunny windowbox gardens and pots filled with bright colorful flowers will generate interest from the pollinators. Or perhaps there’s room for hanging baskets.

Each pollinator has its own preferences. Hummingbirds are attracted to the color red, but bees can’t see it. Bees are initially attracted to blue, yellow, and white, and then will visit a red flower nearby. Hummingbirds can feed from long tubular flowers, but hover flies need short little flowers.

At night, moths can detect white or pale colored sweet-smelling flowers that are open at that time. Almond flowers are pollinated primarily by honey bees, and tomatoes by bumble bees. Butterflies are especially interested in landing platforms, such as those found on plants with wide, flat flowers.

 

What Is An Annual?

An annual grows from a seed that germinates, generally, in spring or summer. It grows for several weeks to a few months, matures, and then begins to flower. Many species of annuals bloom all summer, until frost ends their lives in autumn, roots and all. But, by then, the plant will have set seed, with help from the local pollinators. An annual completes its life cycle within one growing season.

Those seeds will remain dormant over the winter, protected by their seed coats. With favorable weather conditions next spring, some of the seeds will germinate. Many, however, will be consumed by small mammals, birds, and insects.

 

What Do Pollinators Do?

Bumble bees on passion flower vine. Arrangement of flower parts facilitates pollination.

 

Bees and butterflies, and other pollinators, transfer pollen grains from the male anthers of a flower to the stigma, the female part of a flower. Sometimes male and female flowers grow in separate flowers on the same plant (that’s a monoecious plant). And other plants have either all male or all female flowers (dioecious plants). Some have both male and female reproductive elements within each flower (perfect flowers).

Pollinators don’t do this intentionally. Instead, their goal is to collect the flowers’ pollen and nectar. They inadvertently pick up the pollen on their hairs or wings, after being lured in by the flowers and the sweet nectar. Then the pollinators transfer pollen from flower to flower, from plant to plant, as they forage. Thus, they enable fertilization of the ovules, germ cells in the ovary of the female flower.

The male and the female parents must be the same species in order for their chromosomes to be compatible. However, interspecific and intergeneric hybrids sometimes do occur among closely related individuals.

The end result is a ripe fruit with viable seeds. That could be a zinnia’s seedpod, for example, or a blueberry, a peach, or a tulip poplar’s samara.

Cross Pollination

Ah, the genius of nature. Pollen grains and stigmas in many species mature at different times, preventing self-pollination.

Moving pollen among different plants of the same species permits cross-pollination, resulting in stronger genetics and, potentially, a better future for the species. Apple trees and blueberries are two crops that benefit from cross-pollination.

 

Single? Double? Triple?

 

double pink vinca--less nectar for bees and butterflies

Catharanthus ‘Soiree Double Pink’, an annual vinca. Extra petals replace reproductive parts.

 

Flowers with single rows of petals usually have more pollen and nectaries than those with a more complicated petal structure. Plant breeders all over the world have brought to market thousands of these kinds of fluffy triple-flowered hybrids, and they are beautiful. That’s fine, for aesthetics.

But, for bees and butterflies, there’s less treasure for them in flowers filled with petals. Reproductive structures that produce nectar and pollen are often reduced and replaced with additional petals (photo, above). Collecting pollen or nectar from these packed doubles is less efficient, and requires extra visits to gather sufficient quantities. So, pollinators will look for more desirable plants elsewhere, to conserve energy, and avoid such anomalies of nature.

When choosing the varieties for your annual garden, keep these details in mind. Gardens loaded with heavy producers of nectar and pollen (in other words, single flowers) will better serve the pollinators that visit them.

Sunflowers

sunflower seeds for birds, bees and butterfliesMany varieties of recent sunflower introductions have been hybridized to grow flowers with very little or no viable pollen at all. When looking through catalogs, make note of the ones called “pollenless”. These varieties will make less of a mess on the credenza and won’t cause you to sneeze. But they have little to offer bees and butterflies.

Pollenless sunflowers won’t develop mature seeds filled with sustenance for birds and other animals. If pollinators and full seedpods are what you want, ask the seed supplier for varieties that make edible seeds, not just edible flowers.

These varieties of sunflowers will attract pollinators and make edible seeds: ‘Big Smile’, ‘Black Peredovik’, ‘Chocolate’, ‘Giganteus’, ‘Hopi Black Dye’, and ‘Kong Hybrid’. Also, ‘Mammoth Grey Stripe’, ‘Mammoth Russian’, ‘Paul Bunyan’, ‘Royal’, ‘Royal Hybrid 1121’, ‘Sunzilla’, ‘Super Snack’, and ‘Titan’.

Sunflowers have a row of showy ray florets surrounding the disc florets. Disc florets open slowly over time, from the outer edge to the center, ensuring many visits from different pollinators.

The Asteraceae family is perhaps the largest, with 1900 genera and over 32,000 species. (The orchid family is its main rival, but no one knows exactly how many species are in either family.) Members of this extended family include sunflowers, dianthus, lettuce, coreopsis, marigold, zinnia, coneflower, gerbera daisy, chrysanthemum, and shasta daisy.

 

Where to Plant?

 

squash flowers

Thin peduncle (flower stalk) under summer squash flower indicates a male flower. A female flower has a rounded peduncle.

 

A large bed of color around the patio or the mailbox, a free-standing raised bed, and a border close to the vegetable garden are just some of the possibilities. Farmers often include wide bands of wildflowers alongside their fields of crops for better pollination and heavier yields.

One plant that attracts all sorts of pollinators is ‘African blue’ basil. This is a sterile herb—unable to set seed—so it flowers constantly. Other varieties of sweet or flavored basils customarily are used in the kitchen. Plant an ‘African blue’ basil in early summer, close to tomatoes, peppers, and squash to encourage bees to visit the veggies. And let it flower.

Check with local garden centers to see what they have available. Ask for help choosing annuals—seeds or transplants—that attract pollinators.

Before you do any digging, ask your municipality (call 8-1-1) to mark underground utilities. Whether you’ll be tilling the area or digging it by hand, you’ll certainly want to avoid damaging any of those lines.

Locate the garden where a source of water is easily accessible. New transplants and young seedlings will need consistent moisture until they’re established. During summer drought, water the bed thoroughly every week or so.

Sun or Shade?

 

fuchsia flowers

Fuchsia flowers.

 

Find an area that gets full sun if you want lots of flowers. Full sun is at least 6 hours, but annuals will positively thrive in more sun than that. Summer annuals blooming heavily in sun will attract the most pollinators.

But several species prefer shade, such as impatiens. The ‘Imara’ impatiens, resistant to impatiens downy mildew, provides a carpet of color under the trees and shrubs. This plant attracts bees and butterflies, and also hummingbirds.

Where summers aren’t too hot, the fuchsia baskets (photo, above) will entice the hummingbirds to visit every day, like clockwork. This plant does well in dappled shade or early morning sun. And it likes moist soil. As the temperatures climb and fuchsia fails, hummingbirds will flock to the single petunias and salvias, which need lots of sun. They also visit herbs in bloom, including basil and lavender.

 

How Big Is Big?

Hummingbird.

With proper soil preparation and regular maintenance, a plot that measures 10′ x 6′ can become a magnet for pollinating insects. The flowers will buzz with activity from perhaps dozens of species of bees and butterflies, and moths and hummingbirds, too.

This country is home to over 4,000 species of bees alone! More than 20,000 species live around the globe. Some live in colonies, and many are solitary creatures. Interestingly, the honey bee is not native to the United States. It was brought by European settlers hundreds of years ago and proliferated throughout the country.

To increase the activity and the number of pollinating species lured in, make the bed even larger. And include more variety in the plants selected. Use masses of the same plant, and repeat elsewhere in the garden, if you want. Planting larger blocks of a particular color or flower type will attract more pollinators than scattering them about.

If this is your first gardening effort, keep the garden a manageable size so you’re not overwhelmed. There will be maintenance involved! Weeds, no doubt, will have to be pulled. And your garden will need fertilizer a few times through the growing season for the best results. An inch or two of mulch will help cool the soil, retain moisture, and restrain weeds. You can always expand the area as you gain confidence in your skills.

Container Gardens

Even in a very limited space, some of the local bees and butterflies will find the lovely combination pots on your balcony or the patio. Use bright colors, and have your camera ready—for the flowers and their visitors. Once they find their preferred flowers, pollinators will come back day after day.

Remove seedpods to encourage more flowers to develop, although finches and other birds will feed on seeds remaining on stalks late in the season. Fertilize regularly to keep the plants in prime condition. Plants in containers might need daily watering.

 

Added Benefits

  • Vegetables and Fruits

Insects are on a constant lookout for sources of pollen and nectar. You might discover your fruit trees, blueberries, and vegetable crops yielding heavier harvests since installing a flower garden.

Edible crops and plants growing naturally in or around your property will benefit from complete pollination because of the larger populations of pollinators. Include plants whose flowers attract pollinators early and late in the growing season, as well as during the summer months.

 

 

 

I grow many kinds of greens (photos, above) in the cool seasons. Before they’re replaced with summer crops, I allow them to go to flower in late winter to early spring. Most are biennials in the Brassicaceae family, including kale, collards, broccoli, arugula, and mustard greens. Although they don’t require pollination for a harvest, the cruciferous flowers provide pollen and nectar for bees, braconid wasps, hover flies, and other pollinators at the time of year when little else is available.

Pansies and violas provide sustenance for bees that emerge on pleasant winter days. These colorful cold-tolerant biennials grow in garden beds and in containers.

  • Braconid Wasps

Braconid wasp.

The tiny non-stinging braconid wasps are hardly noticeable, but they help keep populations of live-bearing aphids in check. A female braconid wasp deposits an egg in or on an aphid. After hatching, the wasp larva consumes the tissues, killing the aphid. One braconid wasp can parasitize 200 aphids in her brief lifetime. Adults emerge to mate, and a new generation of females will begin hunting aphids.

Pollen is an important food source for the braconid wasps, which will feed on some aphids as well. So, even these tiny insects help pollinate plants.

Photo at right shows a wasp about to deposit some eggs. White aphids have been parasitized, and the others are alive. I’ve often seen leaves with a hundred aphid mummies (the aphid’s empty exoskeleton) attached, with no living aphids.

Planting a wide variety of flowers helps these beneficial insects. Self sustaining populations of beneficials contribute to the overall health of your garden, reducing or eliminating the need for pesticides.

  • For the Birds

Let’s not forget about the birds! Although most species, other than hummingbirds, don’t play a major role in pollinating plants, songbirds certainly have a place in any natural ecosystem. We can play an important part, in our own yards, by maintaining an environment that fosters healthy populations of native animals.

The numbers of many species of birds are declining, due primarily to human interference. We’ve removed their habitat in favor of expansive lawns and non-native trees and shrubs. And we’ve killed off their food sources by spraying pesticides every time a “bug” shows up. Can we please adopt a new attitude?

After all, birds help by consuming huge numbers of insect pests that otherwise could destroy crops or damage potted plants. Birds and bats keep mosquitoes and moths in check. More insects in the garden will support more avian activity.

Restoring healthy populations of all native animals and insects will return balance to the ecosystem. Sometimes, though, the songbirds fall prey to foxes, snakes, or hawks. Predator and prey: yes, folks, that’s how it works.

There are many benefits to living in modern society, but loss of habitat for wild creatures is not one of them. Letting nature be is a crucial step in re-establishing native populations and preventing extinctions.

Let ‘Em Seed About

Finches, sparrows, and chickadees feast on seeds that develop after the flowers fade. So, don’t be too hasty to deadhead the last round of flowers. Allow them to remain in place through the fall and winter, so the birds have another food source available when they need it. Birds will soon recognize your property as a wellspring of year-round sustenance.

Bright yellow and black American goldfinches are fond of zinnias, cosmos, salvias, and asters that have gone to seed. In late summer and autumn, the finches, northern cardinals, thrashers, blue jays, and other animals eagerly consume seeds atop the black-eyed Susans and tall sunflowers. And you might notice plants germinating next spring from seeds the birds overlooked.

Water

Include a source of clean water for the birds. A birdbath in the garden is fine, or you could keep a large plant saucer on the deck. Change the water frequently to prevent mosquito wrigglers from reaching adulthood.

The bees and butterflies also will appreciate a small saucer of water on a hot summer day. Place a flat rock island in the water for safe sipping. A mud puddle, just a bare patch of wet sandy clay, provides moisture and minerals for butterflies.

  • Cut Flowers

Another benefit of growing a garden of annuals is the almost endless supply of cut flowers for indoor arrangements. Include plans to expand the garden next year, to keep the pollinators happy, too. Check with your agricultural extension service to see which flowers last longest in a vase.

Try Some Of These For the Bees and Butterflies

Ageratum, alyssum, bachelor’s button, cleome, cosmos, fuchsia (hummingbirds), herbs, impatiens, lantana, marigold, and pentas. Rudbeckia (annual and perennial varieties of black-eyed Susan), salvia (annual and perennial types, a hummingbird favorite), some of the sunflowers, tithonia, verbena, and zinnia.

Lavender: History and How To Grow It

2019

 

Lavender’s Long History

 

old lavender

 

 

B.C.

 

For many centuries, lavender has enjoyed popularity for its alluring fragrance and for its medicinal qualities. Lavandula dentata was first cultivated on the Arabian peninsula, and other species spread from Greece across Europe. Lavender species might also have originated in the Cape Verde Islands and the Canary Islands off the west coast of Africa.

Thousands of years ago, Egyptians and Phoenicians used the herb in perfumes and during mummification. When Egyptian King Tutankhamen’s (1341-1323 B.C.) tomb was opened by Howard Carter in 1922, claims were made that the scent of lavender could be detected.

 

 

Greek islands

 

Greek traders introduced lavender around 600 B.C. to the Hyères Islands, off the southern coast of France, and to Europe from there. Ancient Greeks used it for insomnia and backache, and in public baths.

CleopatraOther healing qualities of lavender were recorded in the 3rd century B.C., when Greek physician/philosopher Theophrastus (c. 372-287 B.C.) wrote of them in Concerning Odours.

Cleopatra (69-30 B.C.), Queen of Egypt from 47-30 B.C., was able to temporarily preserve her kingdom from Roman rule. As the story goes, she used lavender to win the love of Roman generals Julius Caesar (100-44 B.C.) and Mark Antony (83-30 B.C.).

Upon defeat by Augustus Caesar (63 B.C.-14 A.D., first Roman emperor from 27 B.C.-14 A.D., and heir of Julius Caesar) and Cleopatra’s death by suicide, Egypt then became a Roman province.

 

 

Early A.D.

 

Mary is said to have used lavender when Jesus (4 B.C.-30 or 33 A.D.) was an infant and again when he was crucified. Both the Bible and, later, William Shakespeare’s (1564-1616) work The Winter’s Tale, refer to the herb as “spikenard”. Ancient Greeks called lavender “nard” or “nardus”, apparently after Naarda, a city in Syria where it was sold.

Pliny the Elder (23-79), Roman naturalist and encyclopedist, described relief from “women’s problems” attributed to lavender. His great work, Naturalis Historiae, is composed of 37 volumes, describing natural sciences from agriculture to mineralogy to zoology. Dioscorides, the Greek physician under Nero (37-68), collected herbs and, in 77, wrote about their uses in De Materia Medica.

When the Romans invaded England in 43, they used the lavender they brought with them for bathing, cooking, and giving scent to the air. The Romans and the early French believed in its antiseptic properties, and used it to treat infections and to heal wounds.

It is no surprise, then, that lavender derives from the Latin root lavare, meaning “to wash”. And when the Romans departed England around 410, this plant was left behind, growing in gardens around monasteries.

 

It’s Debatable

Much information online refers to the introduction of lavender to England as late as the 16th century. But as important as this herb was in Roman culture, and because other references claim that they did indeed bring it with them when they invaded England, I will leave it there…unless I find information that clarifies the debate.

 

 

From the Middle Ages Forward

During the Dark Ages, from the late 400’s to 1100, lavender wasn’t used much outside the monasteries. An edict issued by the Holy Roman Empire in 812 ordered monks to grow vegetables, medicinal herbs, trees, and flowers. Lavender was grown at Merton Abbey, near the center of production in Mitcham, in Surrey, England. According to records from 1301, Merton Priory sold lavender to raise money for King Edward I (1239-1307).

Medieval and Renaissance women who worked by taking in laundry used the herb to scent it when washing and also when drying the laundry on top of lavender shrubs. In 12th century England, washerwomen using the herb in this manner were called “lavenders”. Incidentally, the word “laundry” derives from the same root, the Latin lavare.

Monks cultivated it in monasteries as a medicinal herb during the Middle Ages (in European history, approximately 500-1350). A German nun named Hildegard of Bingen (1098-1179) used lavender water with vodka and gin for relief from migraine. And French King Charles VI (1368-1422) slept with lavender-filled pillows.

 

 

From the Renaissance

 

Fit For a Queen Or a King

 

King Henry VIII

King Henry VIII.

 

English King Henry VIII (1491-1547) destroyed the stone monasteries and their medicinal herb gardens in the 1500’s during the religious purges. Because this plant is not native to the area, remaining specimens of lavender were found primarily in private gardens.

King Henry’s daughter (with Anne Boleyn), Queen Elizabeth I (1533-1603), enjoyed fresh flowers every day and lavender conserve, a type of jam. She sought relief from migraines by drinking an herbal tisanne containing lavender.

King Louis XIV (1638-1715) of France bathed in scented water. Around this time, lavender was used to treat headaches, nervous conditions, insect bites, mad dogs, and snake bites. And if people needed their passions stirred, they just tied some stems to the bed post!

 

And For the Rest Of Us

Merchants traveling along the Silk Road, from central Asia to Europe, inadvertently carried the Black Death with them. Bubonic plague spread across Europe from 1346 to the early 1350’s, killing one-third to possibly 60% of the entire population.

Infected fleas on rats transmitted the Yersinia pestis bacterium to people initially through flea bites. But modern researchers now think transmission was airborne, particularly among crowded populations. Outbreaks of the plague were treated with lavender as an antiseptic, but its efficacy is questionable, especially against such a virulent microbe.

Lavender Makes Good Business Scents

Sixteenth century glove makers in Grasse, France, used lavender to scent their wares. I can’t judge the accuracy of the claim, but it was said that those who made or wore the gloves were spared the agony of plague and cholera.

 

lavender soap

 

In the 1600’s, the Shaker community was the first to commercially cultivate lavender in the area now known as the United States and Canada. They used it to treat hyperactivity, flatulence, insomnia, and to fight bacterial and fungal infections. Products sold in distant markets included candles, cleaning products, soaps, and treatments for bee stings, migraines, burns, restless sleep, and skittish horses.

In another European epidemic in 1664-5, many died from the Great Plague. Lavender sold for high prices and was in demand for its supposed ability to ward off infection and to repel insects. People wore bundles of the herb on their wrists. Burglars of the ill took precautions by washing in Four Thieves Vinegar, containing lavender, garlic, and vinegar, to prevent infection. Criminals who were caught and sentenced to digging graves also washed in the vinegar.

Seventeenth century herbalists John Gerard and Nicholas Culpeper wrote about the benefits of lavender. Gerard prescribed it for palsy. A few decades later, in 1652, Culpeper recommended it, in The English Physician, “for all the grief and pains of the head”.

Ornamental Use

In 17th century Ireland, lavender was planted as a low clipped lawn. Later, in the mid 1860’s in County Down, Sir Arthur Rawdon’s Moira Castle maintained an acre of lavender lawn. John Reid, in 1766, recommended lavender as an ornamental walkway edging in The Scots Gardener.

 

 

The Victorian Era

 

Queen Victoria

Both Queen Victoria and Queen Elizabeth I, hundreds of years before her, used herbal products supplied by Yardley and Company of London.

Britain’s Queen Victoria (1819-1901) popularized lavender from its use as a deodorant and floor and furniture cleaners. The Queen appointed Miss Sarah Sprules “Purvey of Lavender Essence to the Queen” and used it everywhere and as a cure-all.

lavender productsAs a strewing herb on floors, it gave out a fresh scent when walked upon. Women sold bundles of lavender, called Tussie mussies, on the city streets. The scent became synonymous with purity and cleanliness.

In 19th century Provence, France, lavender treated dizziness, nerves, convulsions, stomach ailments, infections, palsy, and repelled fleas and other insects.

Lavender is still used in dried flower arrangements, pot pourri (flowers and buds), and sachets (for fragrance and to deter moths). Bath products, candles, and perfumes sold today attest to lavender’s enduring qualities.

 

 

Too Much Lavender?

 

Lavender’s overuse contributed, consequently, to loss of its popularity in the early 1900’s. It also became associated with “old ladies”, although during World War I, medics dressed soldiers’ wounds with it.

And then, in the 1920’s, French perfumer Rene Gattefosse severely burned his arm. He immediately plunged it into a vat of lavender oil, the story goes, and experienced immediate pain relief and, according to some, rapid healing. His book, Aromatherapie, describes applications for wounds and other uses derived from essential oils, and gave rise to…you guessed it…aromatherapy!

 

 

In the Medical Establishment

 

Whatever your beliefs—whether lavender’s popularity is due to its use as a panacea or as a wonderfully fragrant plant—it is beautiful in a sunny garden and it attracts bees, butterflies, and other pollinators.

There are only a few scents that come close to lavender on my list of favorites. But, on one of the “favorite smells” lists online, this scent rated #49! And “petrol” rated…#1! Bacon, freshly baked bread, rain, cookies in the oven, and mowed grass made the top 10 in some of those lists. But…49th?!

 

Caution!

test tubes, lab

The U.S. National Institutes of Health recommends that pregnant or lactating women not use lavender on their skin or take it internally, because the side effects are unknown. For sensitive people, it can cause skin irritations, and can be toxic if consumed.

In prepubertal boys, gynecomastia, an enlargement of the breasts due to hormonal imbalances, can be caused by topical lavender products.

One research study claimed that attaching a pad dipped in lavender oil to the neckline of clothing reduced the risk of falling by 43% among nursing home residents.

Testing for its use in treating canker sores and insomnia resulted in insufficient evidence for its efficacy…

…But let me tell you a little story 

One spring day at the garden center, I was working on lavender topiaries and large specimens—reshaping, cutting back, repotting, and removing all the dead leaves. The scent was just wonderful. It took a couple of hours to clean up all the plants, and then it was lunch time.

As always, I spent the time in my truck, reading and listening to the news while enjoying my lunch. Well…that day was the closest I had ever come, in the past 4 decades, to falling asleep while at work. I had to fight to stay awake!

Normally skeptical of proclaimed powers of plants, I believe this one—that the scent of lavender can induce sleep! No wonder it has been found in bath products for thousands of years.

 

 

Edible Lavender

 

Lavender has been used fairly extensively over the centuries, in conserves, teas, vinegars, and pastries. One of my herb books describes lavender as “an acquired taste”. I made lavender tea, once. Only once.

Apparently, L. a. ‘Munstead’ is the most popular variety for cooking and baking, for its sweeter fragrance and “citrusy notes”. Those seeking new culinary experiences might find lavender in salads, dressings, pasta, sauces, and desserts. If I remember correctly, it was at the Olney Farmers’ and Artists’ Market, in Maryland, where, years ago, I purchased a lavender bud and lemon poundcake that was delicious.

The Lavender Genus

 

Lavender is a member of the mint family, Lamiaceae, and is related to basil, thyme, rosemary, Swedish ivy (Plectranthus), ajuga, Phlomis, and all the salvias, including sage. Their lipped flowers appear in whorls on spikes carried above the foliage. Flower colors range from white and pink, to blue, lilac, violet and blackish purple. Some species in the family have yellow flowers.

The stems of plants in this family are usually, but not always, square in cross-section. Lavender’s resemblance to rosemary has confused many gardeners, but the scent distinguishes one from the other.

There are 47 known species in the genus Lavandula. Leaves are generally simple (with a smooth or “entire” margin) or dentate (with a toothed margin), although some species have pinnate leaves (L. buchii, from the Canary Islands). Leaves and other parts are covered in trichomes, the fine hairs (the indumentum) from which essential oils are harvested. L. lanata (from Latin lanaius), the woolly lavender, is covered in woolly hairs.

Most gardeners associate this genus with silver or gray foliage, but it includes some green-leaved species as well. Also available are variegated cultivars, such as ‘Platinum Blonde’, whose leaves are edged in creamy white.

 

Lavender From Seed

‘Ellagance Purple’ seedling.

Lavenders are small and shrubby in their growth habit, qualifying as woody perennials or as sub-shrubs.

Some will bloom in the first season when grown from seed, and, where they don’t survive the winter, would be considered annuals. I used to grow a variety called ‘Lady’, which had a powerful scent.

A new English lavender called ‘Blue Spear’ will sprout in 2 to 3 weeks from seed, after first being chilled for a week in the freezer. It will perennialize in zone 5 or 6, but can be grown as an annual flowering plant in colder regions. Seeds have to be started very early, though, or the previous fall, for blooms from late spring through summer. ‘Blue Spear’ is an upright plant, growing 11-14″ tall and a bit narrower than that.

***Update***: This summer, I’m growing a variety of lavender from seed that blooms the first year if the seeds are started early in the season. ‘Ellagance Purple’ has dense spikes of deep purple flowers. So far, they look healthy in their 2½” pots, but I’m not sure they’ll have enough time to bloom this year. Photo shows how long the roots are compared to the stem. 7/20/2022

Perennial Species

 

Cross-pollination among the species and varieties gives rise to more variation. Cuttings taken from desirable plants (asexual or vegetative propagation), however, assure the grower that all the young cloned plants will look the same. Many newer cultivars are under plant patent protection and may not be propagated and sold without authorization from the patent holder.

Their common names also vary widely. The English types are well-defined, but when it comes to French or fringed, Greek, Italian, or Spanish, there doesn’t seem to be universally accepted agreement concerning the species they’re assigned to. When shopping for plants, refer to the name of the cultivar (‘Hidcote’, ‘Provence’, etc.) to avoid confusion.

 

Lavandula angustifolia

lavenderZones 5-8. Formerly L. officinalis. Commonly called English lavender, this species grows well there but is native to France, Spain, and Italy. It is used more often in cooking than other lavenders, due to its lower camphor content. This species’ essential oils are considered superior to those of other species. Earlier blooming than lavandins, generally.

Varieties include:

  • ‘Blue Spear’: zones 5 or 6 to 8 or 9. 11-14″ tall, upright growth; deep blue substantial flowers, will flower first year from seed.
  • ‘Ellagance Ice’: compact; large silver-white-light bluish flowers all summer.
  • ‘Ellagance Purple’: zones 5-7; 12-18″ tall, deep purple flowers on full spikes, blooming first year from seed.
  • ‘Hidcote’: 12-18″ tall; tightly budded stems; flowers deep purple.
  • ‘Jean Davis’: 18″ tall; light pink flowers.
  • ‘Melissa’: 24″ tall; pale pink to white flowers late spring to early summer.
  • ‘Munstead’: heat, sun, and humidity tolerant; 12-18″ tall; late spring to early summer flowers from pale blue to shades of purple.
  • ‘Platinum Blonde’ (‘Momparler’): zone 5b. To 18″ tall, culinary. Creamy white leaf margins.
  • ‘Royal Velvet’: 24-30″ stems; velvety purple/navy blue flowers that retain color when dried.
  • ‘Sweet Romance’: 12-18″ tall; purple flowers early summer to fall; a Proven Winners cultivar.

 

Lavandula x intermedia

provence lavender

Zones 5-8. Often called Lavandin or Dutch lavender, this species is a cross between English lavender (L. angustifolia) and spike lavender (L. latifolia). Flowers have abundant nectar, and contribute to the sought after monofloral honey. These interspecific hybrids, denoted by the lower case “x” in the species name, are sterile and cannot set viable seed.

Varieties include:

  • ‘Fred Boutin’: to 3 1/2′ tall. Late summer light blue blooms.
  • ‘Grosso’, also called ‘Fat Spike’: about 3′ tall and wide; very fragrant; medium violet blue flowers. Grower Pierre Grosso (1905-1989) discovered this variety in the Vaucluse district of France. It has a very high oil content and is disease resistant.
  • ‘Hidcote Giant’: to 3 1/2′ tall. Dense, dark purple flowers, dries well.
  • ‘Phenomenal’: zones 5-9; grows 2′ to 4′ tall and wide. ‘Phenomenal’ is more heat, humidity, and drought resistant than others. Introduced by Peace Tree Farms, 2012.
  • ‘Provence’: from southwest France; foliage grows 2′ tall with very tall spikes of pale purple flowers in early summer to early fall; culinary, and commercially grown for the perfume industry. One of my favorites for scent and for tall, see-through flower spikes.
  • ‘Seal’: 4′ to 5′ tall! Strong fragrance, late summer blooms.
  • ‘Thumbelina Leigh’: zones 5 or 6 to 9. A dwarf English lavender, growing only 6″ to 12″ tall, medium blue flowers. This selection comes from New Zealand.
  • ‘White Spike’: to 3 1/2′ tall. Nicely contrasting white flowers, mid-summer. Culinary.

 

Lavandula dentata

Zones 8-9. French or fringed lavender grows about 3′ tall; toothed edges (dentata, from Latin for tooth), light woolly texture; narrow spikes of long-lasting purple flowers beginning in late spring.

From the Mediterranean region, Atlantic islands, Arabian Peninsula.

 

Lavandula stoechas

lavender stoechasZones 8-9. (Pronounced stee′-kiss; [“oe” has long “e” sound, as in “amoeba”, and Greek “ch” has a hard “k” sound.] Derived from the Greek stoichas for “in rows”.) French, Italian, or Spanish lavender is a compact grower, feathery petals at tip of inflorescence. Sometimes called “Butterfly lavenders”.

From France, Spain, Portugal, Italy, Greece; considered invasive in Victoria, Australia since 1920. Can self-seed. This was probably the species commonly grown in ancient Rome and Greece. Eucalyptus fragrance.

Varieties include:

  • ‘Dark Eyes’: 2′ tall. Purple-red flowers May to autumn if deadheaded.
  • ‘Kew Red’: zones 8 to 11. Red-violet blooms with deep pink bracts at tip. From southern Spain. Introduced by Kew Gardens, 1999.
  • ‘Otto Quast’: 2′, prune for fullness. Reddish-purple flowers with deep pink bracts at tip.
  • ‘Silver Frost’ (L. angustifolia x lanata): 2-3′ tall, lax stems. Heavily felted silver foliage.

 

Lavandula pedunculata

Zones 9-10. Also known as Lavandula stoechas subspecies pedunculata. Spanish or French lavender has flowers high above the foliage, and long narrow petals on tip of flower. From Iberia, western Turkey, Morocco.
