The genus Duranta L. contains 17 to 30 species
of tropical trees and shrubs; some are regionally cultivated
as ornamentals. The Duranta we have accepted is Duranta erecta
commonly called Lilac-Flowered Golden Dewdrop, Brazilian Sky
Flower, Duranta, Pigeon Berry, or Sky Flower. It is a rapidly
growing type having dense, somewhat evergreen, foliage and lilac
colored flowers. Renewal pruning is needed occasionally to maintain
a dense manageable form. A yellow foliage variegated form named
Duranta 'Gold Edge' is available. Its brightly glowing gold
and green variegated foliage provides a strong contrast, especially
with red tones. This variety rarely blooms or sets fruit. Durantas
have the ability to tolerate sun or shade. Obviously the blooming
Durantas perform best with more light but the variegated ones
such as 'Gold Edge' actually look best in partial shade. Since
'Gold Edge' is used for its foliage display, blooming is not
important.
This Duranta seems to have ALL of the six characteristics
which make it a Texas SuperStar plant:
(1) It must be attractive and useful to the gardening
masses ratherthan a special few who devote themselves to one
specific plant type. It is described in described in Ornamental
Plants For the Rio Grande Valley as: "Very desirable. (Verbenaceae)
Large, evergreen shrub that produces graceful, drooping branches,
a few thorns, bright green ovate leaves and numerous small flowers
throughout the year. Flowering is continuous in the tropics,
but begins in late summer and continues through autumn in less
tropical regions and is followed by numerous, small, golden
"balls." The fruit is elongated spherical to teardrop
shaped drupes; three-eights to one-half inch long. The fruits
are initially green and then mature to a golden yellow to yellow-orange
color. It can be commonly used as a summer annual for late season
color or perhaps in patio containers. It will be a perennial
planting in zone 9, along the coast or in deep South Texas in
shrub borders.; Duranta attracts birds which feed on the fruits
and it is one of the few flowers that attract both hummingbirds
and butterflies. Other great features of Durantas are their
ability to tolerate sun or shade and their actual preference
for heavy soils.
(2) It must be unique and/or offer desirable and
ornamental characteristics which are not usually available in
commonly sold plants. Durantas as described in Native Shrubs
for South Florida at http://edis.ifas.ufl.edu/EH159, have a
mature natural height of 12-15 feet; a growth rate of medium;
a wide soil pH range (does well in acid or alkaline); a hardiness
zone from subtropical to tropical; require medium to high light
exposure; have medium salt tolerance and drought tolerance;
nutritional levels are low but needs a well drained soil; plants
can become chlorotic in poor fertility sites.
(3) It must consistently perform well for Texas
consumers regardless of their plant growing expertise and their
growing location. Because of the harsh and changeable climate
in Texas we sometimes use perennials as annuals and woody plants
as perennials. For instance, Vitex is considered a small tree
but in North Texas, it freezes to the ground and it a root-hardy
perennial. In places where it does not freeze to the ground,
the Texas SuperStar growing scheme recommends it be cut to the
ground every spring and grown as a multi-trunk shrub. This enables
the easy removal of seed stalks. We also like to find and recommend
root-hardy tropical plants as perennials, or even annuals, in
some parts of the state. For instance, Duranta is hardy as a
subtropical shrub or tree and develops into an irregular spreading
large shrub or small tree 15 to 20 feet tall in USDA zones 10
and 11; it serves as a 6 to 8 foot tall summer annual, herbaceous
perennial or dieback shrub depending upon the severity of winter
temperatures in zone 9; or as a summer annual in zones 8 and
colder. This is the case with other SuperStar plants such as
Firebush (1990 - Hamelia patens); 'Goldstar' Esperanza (1999
- Tecoma stans); Plumbago (2005- Plumbago auriculata (P. capenis);
and 'Texas Lilac' Vitex (2005 - Vitex agnus-castus).
(4) It must be as pest resistant as possible.
An added bonus is for it to be a deer non-preference plant.
Durantas are somewhat resistant to disease and insect attack
but scale insects, caterpillars, and nematodes can be occasional
pests. In some literature, Duranta is described as having poisonous
fruit containing hydrocyanic acid. When put in an area densely
populated with deer, all plants were eaten within three days
with the berries being eaten first. No animals were killed,
the meat presumably was not tainted, and the deer supposedly
were worm-free for several months thereafter.
(5) It must be able to be propagated and mass-produced
in sufficient numbers to meet the increased consumer demand
generated. It can be propagated by sowing the seed in the spring
or from greenwood cuttings.
(6) And most importantly, It must be so attractive
in the sales container that it sells itself to the consumer
who has never heard of the many attributes of the plant. Most
cultivars of this species have a dark blue stripe in the center
of each flower petal, but different selections may have darker
or lighter flowers. Cutting-grown selections of this species
include Duranta erecta 'Sky Blue', which has light blue flowers
and a dense, compact habit; and Duranta erecta 'Royal Blue',
which has dark blue flowers and is also very compact. This species
is by far the heaviest berry producer, which enhances its value
as an ornamental and bird attraction.
I have a hard time remembering scientific names
so when Duranta was recommended, tested and approved to be a
2006 Texas SuperStar Plant, I had to find a way to remember
the name. At my age the solution was simple-think of Jimmy Durante!
In fact, I tell folks that the Duranta was named after Jimmy
Durante even though I think the plant is a bit older than Jimmy
(Actually the genus name honors an Italian botanist and papal
physician named Castore Durantes but who has ever heard of him?!?).
So "Good Night, Mrs. Calabash, wherever you are"!
Nowadays, many gardeners want Texas' tough SuperStar
plants that can fill their gardens or containers and live a
long time without much maintenance. For something that is "old-yet-new",
that is easy, and showy, why not try some Durantas in your garden?
