Variegated Shell Ginger - Alpinia zerumbet
By Onika Amell, tropical plant specialist
Q: I live in Deltona, Florida and hoping to find spreading ginger
with interesting foliage to grow in a partially shaded area in my garden
under a group of trees. Any suggestions?
A: Variegated ginger Alpinia zerumbet variegata is a clumping ginger valued for its
beautiful variegated foliage. The dark, green leaves have striking yellow stripes.
This ginger is sought-after, not only for the stunning foliage but also for its
beautiful flowers. The flowers are different from other members of the
ginger family and appear in drooping racemes from the ends of leafy stems rather
than directly from the rhizomes. This ginger is also commonly known as Shell
Ginger because the flowers resemble seashells! They are pink-tinged, fragrant
and appear in summer.
This evergreen perennial grows in upright clumps 3-5 feet tall. You may
prune the plant to control size.
It does not tolerate drought or a hard freeze but can take a few hours
or light frost (goes dormant in such case). In colder areas, rhizomes should
be dug up and stored in a cool room during winter.
This ginger will love a shaded corner in your garden. Plant it in
organically rich, well-drained soil in full sun to part shade. Keep the soil moist
but not soggy, and spread a thick layer of organic mulch around the plant
for moisture retention. There are no serious insect or disease problems to
worry about!
This ginger can be also be grown as a house plant as long as it has
bright light and humid conditions. It will grow to around 3-4 feet tall as a
houseplant.
Q: I live in Chickasaw, Alabama. I am a beginner bonsai grower. I
received a lovely little Horned Holly as a birthday present and I want to
know if it is a suitable plant to bonsai?
A: The Ilex cornuta - Horned Holly, or Chinese Holly, is very popular as
a bonsai species. It is loved for its very beautiful and distinctive
rectangular foliage and for its small, white flowers which give way to large, red
berries. The berries are larger than those of the European Holly. The leaves are
rectangular and unusually shaped with three large spines at the apex. This
bonsai will take both sun and shade, but semi-shade is preferred in midsummer.
If indoors, give it plenty of bright light. When kept outdoors, your Horned
Holly bonsai will need some frost protection and should be sheltered from
strong or cold winds.
It will need a fair amount of water and should not be allowed to completely
dry out. Watering during the heat of summer is especially important, as well
as in spring right before the fruit production, and should be reduced during
winter. This species will also appreciate regular misting of the foliage.
Repot this bonsai every 1 to 2 years in early spring, using bonsai soil - TopTropicals
Adenium Soilless Mix. Fertilize the holly every two weeks throughout the
growing season using either a balanced fertilizer diluted to half strength.
We recommend for this purpose Tropical Greenhouse Plus - Plant Booster. Pruning should be done in
early spring.
Horned Holly is also very popular as a hedge plant as it grows dense
and compact. It will grow to between 3 and 5 feet tall and will spread to an
equal distance, giving it a round, shrubby form. It is cold hardy! Zones 6
through 9. It will tolerate a wide variety of soils as long as it is
well-drained. It likes sun or part shade. It is heat and drought tolerant once
established, and are often used in xeriscaping. Its branches produce dark olive-green
foliage that is often cut for indoor decorations during the holidays.
Q: I have a bare spot in my front garden, behind a low wall, in
part-sun. I'm hoping to find an evergreen, flowering ground cover that will
cover it quickly. Any ideas on finding something with the ability to eventually
also cascade over that wall? I live on Marco Island, Florida.
A:Barleria Repens - Small Bush Violet, is a tough, fast-growing evergreen
that blooms from late spring to autumn. Of the many Barleria we see in the
tropics, Pretty in Pink is one of the most striking! The name tells the whole
story: pretty and pink. A lot of gardeners enjoy using them as a ground
cover. They will quickly cover a large area - their stems root readily as the
plant crawls along. They are easily propagated by lifting the rooted runners or
using cuttings. They also reseed easily. Flowers are followed by seed pots
that explode open when dry, dispersing 4 seeds at a time! But perhaps best liked
by many gardeners, is their habit to cascade. It will be well suited for
covering the bare area in your garden and spilling over that wall beautifully.
When used as a ground cover, remember to pinch out young shoots to
encourage bushiness and prune the plant back hard after flowering to keep it
neat.
Barleria repens will also adapt to different situations in a garden if
you need them to. Although they usually form a rounded to spreading bushy
shrub, 2 ft high by 3 ft wide, they will climb when you give them support. They
are often allowed to lean into nearby trees and shrubs.
Hardy to 28F, Barleria repens is pest-free and fairly frost-tolerant.
They love sun and part shade, as well as well-drained soil and plenty of
organic material. Avoid planting it in deep shade as it will get leggy and
reluctant to flower.
They will thrive when fed with a slow release fertilizer at intervals
of 6-8 weeks, throughout the growing season.
There is another cultivar of this exact variety that has blue-purple
flowers, it is called Purple Prince! It couples perfectly with Pretty in Pink! :)
Q: I live in Mesa, Arizona. I am considering purchasing two of
you Triple Sec Mango trees. Can you please give me some information on this
variety and how to grow it successfully here in hot and arid
Arizona, if at all?
A:Triple Sec Mango is a new name for the superior variety Seacrest. The
aroma of this fruit resembles Triple Sec - an orange liqueur. It's a juicy,
mid-season variety that has good disease resistance.
Mango has pretty good heat and drought tolerance. It loves sun, but there
are a lot of factors to consider when growing Mango in your area.
Check your soil. Soil quality is always first and foremost: when you
live in an area of Arizona with
hardpan (extremely compacted desert soil) or caliche (layers of soil
cemented by calcium carbonate) you
will have to learn how to deal with such soil types. Amend the soil as
needed.
The best time to plant is spring or fall to give your Mango a chance to
get established before the really intense Summer heat starts. Alternatively,
protect the tree with a shade cloth. Tender, new growth will not stand a
chance unprotected, especially newly planted and/or young trees.
Mangoes are tropical and sensitive to frost and freeze damage. Young
trees especially will also need winter protection when temperatures go near or
below freezing. Always plant trees in a location where they will be protected
from cold wind. Consider staking your newly planted Mango trees for the
first year. It's never a bad idea to even stake during periods of high winds.
Make sure your planting site has very good drainage. Always use a good
quality mulch around your tree as it helps to trap moisture, keeping the
ground and the roots beneath it cool. Keep mulch a couple of inches from the
trunk of the tree. Avoid a location that gets full day sun. Morning sun,
afternoon shade is ideal. Give regular watering until the tree is established. Once
established, water only when the soil feels dry.
Fertilizer with a Mango-Food. A foliar spray of micronutrient solution is always
recommended during the active growing period. Use plant stimulants and microelements to improve cold hardiness and vigor.
