Plant of the Month: Golden Dewdrop - Duranta erecta
Stevie's Pick: what's in bloom?
Our exotic plant grower Steven Gowdy is featuring the most interesting plants he discovers and recommends today while working in TopTropicals greenhouses.
Duranta - Golden Dewdrop - is simply stunning with cascading flowers in
abundance. Either it has lavender, blue, or solid white flowers, it is a
sight to behold. The popular name Golden Dewdrop is inspired by the clusters of
bright orange-yellow berries that follow the flowers, in such quantities that
they often cause the slender branches to droop gracefully.
Duranta erecta blooms off and on all year and can be pruned to size as a
bush or a standard tree. If let go, it can grow up to 20 feet tall and wide.
Durantas are excellent butterfly and hummingbird attractors. They will
complement your tropical garden or a stand alone in your Southern landscape.
Great for providing a color contrast in the landscape, they are especially
well-suited as a bright-colored background or screening.
White
Golden Dewdrop has pure white flowers that appear in loose clusters, and
both berries and blossoms are often seen on a plant. This evergreen fast
growing shrub spreads and arches to 10 feet tall and wide and is great for live
hedges and covering fences and corners.
Variegated variety, also called Variegated Sky Flower, is grown for its summer flowers, and very showy
leaves that are dark green with bright white variegation and creamy-yellow
margins around the one inch long serrated leaves.. In the summer, cascading
clusters of blue tubular flowers appear followed by wonderfully contrasting
orange-yellow berries.
In mild climates, Durantas can be in flower nearly year round with flowers
and fruit appearing at the same time. It does best in full sun with frequent
deep watering and is pretty hardy, to about 20-25F. It is a good choice for
espaliers, as a small tree or large bush; all forms benefit from frequent
selective pruning. Prune back in late-winter to encourage a more compact shape
and strong flush of fresh spring foliage. Requires moderate watering in a
well-drained soil.

Plumeria cold protection
Q: We have a purple-flowering plumeria which resides on our sunny deck during the warm months and then Winter vacations on our back porch where we can close the plastic film windows and where it stays above 50 degrees (overnite) until it can get moved outside again. We live in zone 8+ in South Carolina and I would love to plant it outside. Do you think if we ghost-covered it when alerted that we would have an overnite freeze, that it would survive being planted in the ground and recover to flower when warm? I don't believe the soil in our yard has ever frozen below the top 1/2 inch or so, and never for more than a few hours at a time. What do you think?
A: Plumerias are tropical plants, which means, they need frost-free environment. Even if the ground is frozen only on "the top ½" or so"- this may be enough to kill the plant. From our experience, plumerias can withstand a few hours of windchill frost (not frozen soil), but even if they survive, they may get some branches damage, and recovery may take so long that the plant may not even bloom the next year. So I wouldn't take that risk even with a ghost-cover cold protection. We have customers who grow tropical plants in the ground in colder areas, but they have greenhouse protection: this means, the soil is warm and the air temperature is maintained above 45-50F. For example, this Greenhouse in Virginia.
We recommend to continue growing your rare plumeria in container and
move it inside when temperatures drop below 50F (recommended) and for sure when
they drop below freezing. Plumeria can take a cold night (a few hours of
upper 30's) as long as it is followed by a nice warm sunny afternoon with at
least upper 50s. Otherwise, keep it indoors. The good news is, since plumerias
are deciduous and have no leaves in winter, low light level won't affect the
plant.
Just make sure to minimize watering and keep the plant on a dry side
until it starts growing new leaves in Spring. You may continue fertilizing once
a week with half-doze of Sunshine boosters - Sunshine TotalFeed. This will maintain the plant healthy and prepare
for the blooming season in Spring.

Fragrance of Angel Hair Jasmine
Q: I got angel hair jasmine, it started flowering, but it does not have any smell. What can be done?
A: Jasminum pubescens - Angel Hair Jasmine has very fine fragrance. It is
not as strong as some other jasmines like Sambac for example. However flowers do have a sweet scent especially in
the early morning hours, as long as the plant is well-established, grows in
a warm and humid environment. Keep in mind that flowers on young small plants
that do not have a developed root system, may not be as fragrant as on
mature vigorous specimens. Also, this jasmine needs a full sun location and
regular fertilizer for profuse flowering.
We recommend the following fertilizers to boost flowering energy:
- Pink N Good Daily Plant Food - Flower Booster
- Plumeria Top Dress - Smart-Release Booster
Use microelements at least once a month to improve plant vigor and quality
of flowers

Grafted Guanabana - what is the trick?
Q:Should I buy grafted Guanabana or a seedling? It is a big price difference. I have heard that Annonas fruit within 3 years from seed, why do I need a grafted tree?
A: Annona muricata - Guanabana, or Soursop - is known as the best tasting
Annona fruit. Many fruit lovers and gardeners want to have this tree in their
plant collection, and the first question they always ask is: "How soon will
it fruit? I can't wait to enjoy its deliciousness!"
Most Annonas start flowering and fruiting at a young age, 3-4 years from
seed. Annona muricata seedling takes longer. You may read more information on
how to grow Guanabanas from seed, even in a pot, even indoors - in Tropical Treasures Magazine issue # 7. Although it may take up to 15
years to see the fruit...
Now we have a solution to get this fruit sooner - a grafted tree! It
will fruit within a year after planting. The secret of grafting Guanabana was
almost lost (it's a tricky one to graft) and grafted plants were nearly
impossible to find. Now we have them! Quantities are limited.
Keep in mind that Guanabana is very cold sensitive and won't tolerate
even light freeze. However it is still relatively easy to grow even in
subtropical areas: the tree is small, and if tree grown in ground, a simple cold
protection structure can be built around it using basic wood or pipes (metal or
PVC) and covered with plastic for a few weeks of cold weather. Grafted
Guanabana is also a perfect choice for container culture (hand-pollinating maybe
required).
Photo: This grafted tree was planted less than a year ago, and was covered in winter with cold protection for about 8 weeks. Within a year, it has 4 large fruit on it!

Looking for the rarest plant? This is the one!
Stifftia chrysantha - Pompom, Rabo-de-Cutia
Looking for the rarest plant? This is the one!
Stifftia chrysantha is an exotic, rare flowering small tree with
spectacular flowers, endemic to the vast tropical savanna ecoregion of Brazil
called Cerrado. It grows into a bushy, attractive tree between 8 and 15 ft tall
and starts flowering within 1.5 - 2.5 years from seed. It is a very rewarding
plant that blooms 9 months out of the year, starting in Winter with great
intensity during July-September, with each flower staying on the plant for
several weeks. Seeds ripen from September through November.
The tree belongs to Aster family (Compositae) and has nothing to do
with Powderpuffs which are from Bean (Fabaceae) family. The flower has 30 to 40
green, imbricated scales with short hairs, and actinomorphic corollas are
orange below and darker above. After flowering, the inflorescence blows apart,
which would scatter seeds. The dried center remaining is very attractive, like
a small dried flower, and lasts for many months.
Stifftia can be grown in full sun to partial shade and is relatively
cold tolerant, can take short cold spells.
The plant doesn't like wet feet
and heavy/soggy soils; requires very well drained, acidic soil. We strongly
recommend to use our professional soilless mix. Let soil
slightly dry between waterings. It can be grown in full sun to partial shade and is
relatively cold tolerant, can take short cold spells. If grown in a pot, try
to keep the container shaded because roots don't like to be overheated. The
plant needs monthly applications of slow
release fertilizer as well as extra iron - use micro-nutrients to
keep leaves green and healthy.
