The Texas SuperStar* plant for the summer of 2005 will surely join this
elite group
of SuperStar "old-plants-revisited-and-revitalized" category to
become a million-dollar seller. It is the Texas Lilac(ياس بنفش) Vitex*, or Chaste tree(5انگشتي)
(Vitex agnus-castus).
This tree is also known as Mexican lavender,
monk's pepper, lilac
chaste tree, hemp tree, sage tree, or Indian spice. It is a native of China and India, although long ago it became
naturalized throughout certain areas of the United Stated. Records indicate
that Vitex has been cultivated in the U.S. since 1670.
For
people living in the warmer parts of the South, the lilac
chaste tree has been the shrub or
small-flowering tree of choice to mimic the much beloved lilacs that are restricted to cooler regions. It
grows best when planted in full sun and in a location that drains well. It will
grow well in all areas of Texas,
in both acid and alkaline soils(خاك قليايي). It prospers in hot and dry environments. The Texas
Department of Transportation recognizes its toughness, and plants Vitex in highway medians. It is a spectacular
butterfly-attracting plant and is deer resistant in that deer will not eat it,
although they can damage it with their antlers if it is allowed to grow very
large.
So, if all of this "good stuff" is known about Vitex, why isn't it more popular than it is? This is
where the work of the SuperStar horticulturists begins. The older selections of
Vitex had small spikes(سنبله ها) of flowers which
were pale lilac, mauve, off-white or light pink. The blooms were small and, for
the most part, unattractive. Horticulturists now have identified and tested
improved varieties such as 'Montrose Purple', 'LeCompte' and 'Shoal Creek'
which have spikes(سنبله ها) as long as 8 to 12 inches. All of these will be marketed under
the name of Texas Lilac Vitex*.
The bloom spikes on these improved varieties
are not only large and beautiful, they also are fragrant and provide
long-lasting cut flowers. However, after the bloom spikes
have provided several weeks of spectacular beauty, many aromatic black or
dark-brown seeds are produced. Not only do these seeds prevent a profusion of
additional bloom spikes, they may, in some
regions of the state, produce a seedling population that will not have the same
characteristics as the original plant and become a nuisance.
The obvious answer to this problem of seed production and resulting
reduction of blooms is to promptly cut off or deadhead the spent bloom spikes
after the first flowering so that the shrub will bloom again. So, if the answer
is so simple, why haven't people been doing it for the last 100 years? The
problem is how rapidly the Vitex grows.
Vitex reaches heights of 25 feet in good soils, but
most specimens in the San Antonioseed pods(فكرمي كنم غلاف
دانه يا شايدم آلبومين منظورش ه) cannot be easily reached and removed. Peach growers prune their
trees for the same reason that you will need to "prune"(آلو) Vitex - so that they can reach the peaches
during harvest, just as you will want to reach the seed pods when its time to
remove them.
area are about 12 to 15 feet tall. It is a tree that is inclined to be about
twice as wide as it is tall, so folks have the tendency to allow the plant to
become overgrown and consequently,
However, to some people, cutting is like killing. If you have that attitude,
you will not enjoy the maximum floral display of the Texas Lilac Vitex* - only the spring bloom. The Texas Lilac Vitex* must be cut after EVERY bloom cycle,
and cut back to the ground EVERY winter. If you live in an area with a large
deer population, the deer rubbing their antlers on the Vitex will
"prune" the plant to the ground for you, or at least remind you to
cut the ravaged stems(ساقه) back.
Remember, shrubs(گياهان چندساله) that bloom after June usually do so from buds that are formed on shoots(بخش هاي هوايي) that grow the same year. These shrubs should be pruned in late winter to promote
vigorous shoot-growth(رشد بخش هاي هوايي) in spring. Examples of shrubs like Vitex
that bloom on current season's growth include: Buddleja
davidii or B. globosa (buddleia or butterfly
bush), Hibiscus syriacus (shrub althea),
Hypericum spp. (St. Johnswort), Lagerstroemia indica (crape myrtle), and Rosa spp. (roses). Most of us know to prune roses twice
yearly (early spring and fall), some of us realize that crape myrtle seed pods
should be removed to simulate repeat blooming, and now we know that in order to
make the Texas Lilac Vitex* produce an
abundance of beautiful cut flowers that furnish a constant source of butterfly
flower nectar, this plant MUST be cut often and severely.
Depending on weather and cultural conditions (fertilizer(كود), water, region of the state, etc.), plants
will bloom again within six weeks of seed pod/stalk removal. It is best to
remove the seed pods before they harden-the sooner after the bloom petals
To annually maintain the plant in a desirable size range of six feet, plants
should be cut within a few inches of the ground every winter. It will sprout
and bloom by June if cut to the ground in winter. If the plant has gotten large
during the previous growing season, you can use a small chain saw to cut them
back, then use hedge shears to deadhead them during the growing season. Cutting
the plants back will make the spikes much longer but, of course, there will be
fewer of them (at least with the initial cut-down)-very similar to the thinning
of fruit crops to produce larger, high-quality fruit. To stimulate rapid
re-blooming and larger flower spikes, three pounds of a slow-release
formulation of lawn fertilizer per 100 square feet should be scattered around
each plant after spent blooms have been removed. Make sure the lawn fertilizer
does NOT contain an herbicide. drop, the better, and the faster the plant
will come back into bloom.
Because of the growing conditions in much of Texas, many perennials are best used as
annuals, and many shrubs or small trees are best used as perennials. This has
been the case with the three very successful Texas SuperStars* - firebush,
esperanza and perennial hibiscus. In most areas of Texas, firebush and perennial hibiscus die
to the ground every winter. Esperanza-and now Texas Lilac Vitex* - should be
cut to the ground every winter to keep the plant manageable from
season-to-season.
The butterfly craze has created a new interest in growing the ultimate
nectar plant known as buddleia or butterfly bush. Unfortunately, the majority
of buddleia do not perform well in most areas of Texas and are not reliable perennials.
However, the Texas Lilac Vitex* can become the "buddleia" of Texas if handled
properly.
For those of you who want a medicinal plant for a SuperStar, Vitex fills the
bill. Vitex agnus-castus belonged to the official medicinal plants of antiquity
and is mentioned in the works of Hippocrates, Dioscorides and Theophrast.
The first specific medicinal indications of Vitex can be found in the
writings of Hippocrates, 4th Century B.C. He recommends the plant for injuries,
inflammation and swelling of the spleen. He also suggests using the leaves in
wine for hemorrhages and the "passing of afterbirth". In his
"Corpus Hippocratum", Hippocrates writes, "If blood flows from
the womb, let the woman drink dark red wine in which the leaves of the chaste
tree have been steeped. A draft of chaste leaves in wine also serves to expel a
chorion held fast in the womb".
Dioscorides attributed to the fruit a hot and astringent activity, and
recommended it for wild animal bites, swelling of the spleen and for dropsy.
Decoctions of the fruit and plant were used as sitz baths for diseases of the
uterus. The English name for Vitex agnus-castus, "chaste tree", is
derived from the belief that the plant would suppress libido in women. In Greek
cities, festivals in the honor of Demeter included a vow of chastity by the
local women. In Europe, the Catholic Church
developed a variation on this theme by placing the blossoms of the plant at the
clothing of novice monks to supposedly suppress their libido. The common name
"Monk's Pepper" refers to the medieval belief that utilizing potions
made from the berries helped monks maintain their vows of chastity. There is
nothing in contemporary scientific literature to suggest that it actually does
suppress the libido. Early American physicians used it to stimulate lactation
and as an emmenagogic. It does, however, have an excellent track record in
relieving complaints collectively referred to as premenstrual syndrome.
So, whether you want to stimulate the presence of butterflies in your backyard
with a drought-tolerant, pest-resistant plant, or whether you want to try some
ancient herbal remedies, the new Texas Lilac Vitex* is the plant for you.
