THE LAVANDINS The English Lavender Hybrids, sometimes
referred to as Lavandins; come in third in the bloom cycle, starting
just as the the English Lavenders are finishing, and continuing
to mid summer.
These are the workhorses of Lavender. They do it all: bloom lots,
grow just the right size, and smell like a million bucks. Provence
and Grosso are the best known of these, but there are many others,
including Abriali, Fred Boutin, Dutch Mill, Grappenhall, Seal, Hidcote
Giant and White Grosso. These are the ones to line the drive or
border the garden with.
The botanical name for the Lavandins is Lavandula x intermedia.
The x means it is a cross with two plants and we know which two.
In this case, it is L. angustifolia and L. latifolia. The intermedia
means that these crossed plants have qualities of both parents,
or it is intermediate between them.
Lavandins have long gray leaves, twice or more the size of L. angustifolias.
They also grow much larger and faster.
Abriali Lavender is one of the older Lavandins. Also beautifully
colored, it is a little shorter than Grosso and was used for oil
production before Grosso was developed.
Dutch Mill Lavender has vibrant grape colored flowers that stand
out well against darker flowered lavenders like Grosso. Because
it is a lighter shade, it shows up better in very sunny situations.
Fred Boutin Lavender, discovered in 1980, is a long-stemmed beauty
with a medium purple flower. It has very silvery leaves and excellent
fragrance.
Grosso Lavender is cultivated for oil used mainly in the cosmetic
industry. It makes great Lavender bouquets and wands. Grosso Lavender
has beautiful purple calyxes instead of the normal green calyx of
most lavender.
White Grosso Lavender is a must have for the garden and for the
vase. Its swan white blooms complement the purples of other lavenders
and they stay white when dried.
Grappenhall Lavender is a tall, long-leaved Lavender with a slender
bloom and a medium purple flower. Because the leaves are longer
this plant has the energy to grow quickly and in larger proportions.
Hidcote Giant Lavender has dark purple flowers that are close together.
It is a striking plant in the landscape.
Provence Lavender has a long, slender flower wand that is useful
for dried bud collecting. The buds come cleanly and easily away
from the stalk.
Seal Lavender is a highly fragrant bright purple old time favorite
that is perfect for crafts or hedges.
Any way you look at them, lavenders are luscious long stemmed,
aromatic necessities.
PLANTING, GROWING, PRUNING, HARVESTING AND USING
Most lavenders are started from cuttings taken from Mother plants.
This is both fast and accurate, producing an exact replica of the
original plant.
Starting Lavender from seeds sounds like a great inexpensive way
to get all the lavender you desire but it can have some major drawbacks.
The first obstacle is finding the seeds. Even though Spanish, Yellow,
and other species Lavenders can be started from seeds, it is usually
only the Lavandula angustifolias--Hidcote, Vera, and Munstead--
that are available as seeds.
The second drawback is what we call ' low and slow' germination.
Lavender seeds have a short shelf life, and therefore the germination
rate (how many seeds out of 100 come up) is usually pretty low.
They can also take a long time to sprout (two weeks or more) and
this invites fungus to the seed tray, often causing the seed to
rot before it can sprout. Seeds benefit from light, so cover lightly
when sowing. The germination temperature should be around 70 degrees
and spring seeding is more successful than fall seeding. Those seeds
that do sprout will take one to three months before they have enough
roots and top growth to allow successful transplanting. Adding fertilizer
to the sterile medium used in the seed tray can help the little
plants get off to a better start, but it can also invite fungus
in cool, humid situations.
The third disadvantage is the time it takes for the seedlings to
get to a good size. After they are transplanted into small pots,
the plants will be about three inches tall and have a single stem.
It will take another three months or more to make a plant substantial
enough to transplant to a larger pot or to the garden.
The fourth inconvenience is the difference factor. Because little
care has been taken over the years to insure that the seeds have
not crossed with each other, the plants will be varying shades of
color. They might also vary some in height and width. This was the
surprise our customer had. The perfect hedge of Hidcote Lavender
she had dreamed about and worked so hard to grow the plants for
turned out to be more like a cottage garden: still beautiful, but
irregular in form and color.
And, lastly, the most popular Lavenders (the Lavandula x intermedias;
sometimes called Lavandins), either do not make seeds or the seeds
are sterile, so you will never see a seed packet of these.
The most important factor to get right with Lavender is drainage.
Soggy areas should definitely be avoided. Incorporate organic matter
if necessary to make a loose friable soil. Compost is the best amendment
because it is fertile and has uneven particle sizes. Uneven particles
in the soil create better air spaces and give the roots better anchors
to attach themselves to. Check the soil's pH (potential hydrogen)
to make sure it falls somewhere between 6.5 and 7.5. If the soil
is too acidic the Lavender will not thrive. If the soil is too alkaline,
the nutrients are 'tied' up in the soil and the plant cannot use
them. Yellowed growth can be indicative of a soil that is out of
balance. Adding compost can help to balance the pH.
If you are going to plant a hedge or a massive amount of Lavender,
make sure the ground is cleared of weeds. Solarization works to
remove not only tenacious weeds, but also kills weed seeds. Small
Lavender plants cannot compete with aggressive weeds, and weeding
after they are planted can be a huge hassle. Weeding often becomes
such a chore that Lavenders are overrun and eventually die in a
neglected field.
Mulching with a small particle mulch or compost after planting
helps with the weed control, but avoid mulching right up to the
stem of the small plant. Instead, leave a collar about two inches
wide around the plant.
If you are in hot, humid areas, try planting Lavenders in a raised
bed or on a mound. Leave plenty of room between plants for air circulation.
Lavenders are not ideally suited to heat and humidity, so be prepared
for problems, such as fungal disease and rot.
For ultimate show, space plants according to their height measurement.
For example, a Grappenhall Lavender is listed at 3 to 4 feet. By
spacing these 3 or 4 feet apart, the effect when the plant is blooming
is spectacular. If it is more important that the plant make a tight
row or hedge, then plant closer together.
If planting in pots, make sure to repot every spring into a larger
container with fresh soil to allow the plant to continue to mature
and to provide as many flowers as possible. A good, coarse, sterile
potting soil with organic fertilizer mixed in works best.
In the ground or in a pot, full sun is a must. If the garden is
crowded, plant near a south-facing wall. Even the Lavender at the
north end of the row will be shorter and bloom later. In hot areas,
some late afternoon shade can be tolerated without sacrificing the
glorious mounded shape and rising pincushion effect of the flower
wands.
Lavender in the field rarely needs fertilizer, especially if compost
is applied as a mulch. More often, problems arise because the soil
is not healthy. Avoid chemicals in pesticides, herbicides, and fertilizers
that kill or starve the beneficial organisms in the soil.
In arid regions with no summer water, irrigation will be necessary
for the survival of the plants. While Lavender is extremely drought
resistant once established, it grows larger and produces more blooms
with regular watering. This means that when it is dry, water it.
While this may sound obvious, it is important to let it dry out
a bit before soaking it again. In humid areas, this can be difficult
and the excess moisture often causes death.
Zones 8 and up can plant Lavender in spring and fall, but other
zones are better off with a spring planting after the last frost.
If fall planting is to be tried, plant at least two months before
the first frost. It is important that the plant actually make good
root development into the native soil before severe winter weather
occurs. Lavender grows slowly in the fall and often plants are not
sufficiently established to get through winter rains and cold.
It takes about three years for a Lavender to reach full size. Plants
should be pruned every year immediately after bloom. Pruning should
not be confused with harvesting. Pruning is necessary to extend
the life of the plant. Lavender flower wand stems are usually a
bright green while Lavender leaves are gray. Cut back not only the
flower stem, but also about a third of the gray-leaved stems as
well. If the plant has been neglected, it can be cut back further,
but avoid pruning back so far that only woody stems with no leaves
are showing. A plant pruned into the wood may push out latent (sleeping)
buds or it may die.
Harvesting Lavender is one of the most enjoyable pleasures any
gardener can have. Lavender flower heads look gray before the flowers
open. They are devoid of most color and it is easy to become impatient
waiting for them to burst into bloom. Once the color is bright and
vivid, that is the time to start cutting. Cut the flower stems during
the cool of the morning after the dew has dried. In humid areas,
try to cut on dry days. For arrangements, it is easiest to arrange
the Lavender while it is fresh and supple. This can be done in the
garden if it is not too hot. If the weather is very warm (even in
the morning), take a bucket of water, filled about a quarter of
the way, and submerge the cut end of the stems into the bucket.
Remember that the plant cools itself by releasing its fragrant oils,
so the more heat they are exposed to the less oil, and fragrance,
for you. Arrange out of direct sun as soon as possible. Stand them
in a dry vase and the fresh flowers become dry ones. Or use fresh
in small groups as an accent for a fresh herbal wreath. If the flowers
are to be used later, dry in small groups by tying with a twist
tie and hanging in a dark dry place or individually by spreading
them on a screen and drying out of the sun. Once dry, the buds can
also be stripped and used as bulk for potpourri, sachet, or even
cooking. Some Lavenders hold their buds better than others. Grosso
Lavender is preferred for wand making and dried arrangements because
the flowers stay on the stem better. This is something to consider
if your primary focus is to REMOVE the dried buds for bulk use,
such as potpourri. Provence Lavender is more suited to this because
the buds release easily from the calyx (too easily for dried bouquets
or wands).
The further along in the bloom cycle, the more fragile the flowers
seem to be. Actually, what happens is that the little flowers fall
out and what is left is the calyx and any unopened buds. Most Lavenders
bloom for about 5 weeks, so do a little experiment in your garden
to see when the harvest is best for your needs.
If you are harvesting a lot of Lavender, try this tip from the
Lavender experts at Purple Mountain Majesty.
Hand harvest by sticking your left thumb in the flowers to be cut
while simultaneously hooking the flower stalks in front and below
your left hand with a Chinese sickle. You pull and cut the first
bunch into your left hand with one motion. The process is repeated
without removing the cut material until you have completely cut
counterclockwise around the plant essentially twisting the cut stalks
around the center uncut stalks as you go. This keeps even the largest
bundles under control because the whole bundle winds around the
center uncut stalks creating enough friction to keep everything
together and eventually captured under your left arm. If the bundle
is too big for your grip, then it is kept from falling apart by
your thumb and the center stalks, which you cut in a final cutting
motion starting with a reversed sickle in front of your left leg
and vectoring in a direction that is away from the harvester.
Lavender smells like it should taste wonderful, but the taste of
most Lavenders is a little like turpentine. The flavor is not one
that can be easily defined nor is it one most people like right
away. It is like a fine wine with many subtleties. Both fresh and
dried flowers and leaves are used in culinary preparations. Recipes
using Lavender are generally on the sweet side but Lavender can
be used to replace Rosemary and other strong tasting herbs. Or,
it can be blended with other herbs, as in herbs de Provence. This
mix, used in many savory dishes, often finds dried Lavender leaves
and flowers mixed with other members of the mint family, like Rosemary,
Sage, Oregano, Thyme and Mint.
Used not only to make life smell richer and more tolerable, but
also as a medicinal relief for ailments from headaches to insomnia,
Lavender oil has always been a prize. In times past, most Lavender
oil was distilled from the angustifolia species of Lavandula.
Often referred to as English Lavenders, these Lavenders are native
to the western half of the Mediterranean. Now cultivated in many
countries, it was thought the finest Lavender grew in England and
thus the common name English Lavender evolved and is still the name
most folks use when referring to Lavender products.
Because Lavandula angustifolias are small, and because they are
pretty particular about where they grow, it takes a lot of plants
to produce one ton of oil; so most Lavender oil now comes from the
Lavandins. These are hybrid Lavenders that have the English Lavender
as one parent and the Spike Lavender (Lavandula latifolia) as another.
These Lavenders tolerate a more diverse climate, and, since they
are larger, produce more oil per acre. This oil, while less expensive,
is not as good for medicinal purposes as English Lavender oil, but
it is widely used in the perfume and craft industries.
And, when you hear the term French Lavender Oil, don't be confused.
The French nom de plume refers to where it is grown and not which
plant it is from. French Lavender oil is really English Lavender
oil produced in France! |
