New Introductions of Flowering Trees by Dimitris
Petropoulos
Winter has come
to us in unrelenting waves of fierce winds accompanied by undulating
temperatures and a lot of rain. Plants respond to these changes; many cast off
their leaves and flowers, others stoically but subtly alter the color of their
leaves.
For some, this is the time for evaluation of our
gardening efforts. Those who may want to add something out of the ordinary,
difficult to find, or just plain rare, face quite a challenge.
1. Radermachera capitata : around 18 feet
tall, likes full sun. The trees have straight trunks, with an elegant canopy of smallish leaves.
The effect of the leaves is almost fern-like. At the branch tips, 20-inch long, dark
strand, multi-stemmed, flower spikes droop with many deep red, small
satin-textured, bell-shaped flowers. These trees are laden with 2-foot long, thin,
bean-shaped pods, as well as new developing flowers. This seems to indicate a long,
repetitive bloom cycle.
2. Randia spp. (possibly exultata):
reaches a mature height of about 15 feet in dappled shade. The canopy is elliptical with
branches low to the ground. Large shiny leaves and bouquets of star-shaped,
funnel-form flowers (opening a pale chartreuse color, maturing to white) are at the
apex of each branch. The seeds are about the size of a lemon and ripen to a
golden amber color. A full grown tree is often laden with fruit and flowers, at the
same time, through the Spring until early Winter.
3. Phaleria octandra: also grows to about
15 feet in semi-shade, and is elliptical in form. Leaves are 8 to 10 inches long, naturally
droopy, waxy-textured, and accentuated by a burnt scarlet stem. It has
flowered in late Autumn and again in early Winter in Miami. Four to five inch,
ice-white, porcelain-textured bouquets crown each branch. The perfume is strong, gently
reminiscent of gardenia, jasmine, and honeysuckle blended into one. This open crown
tree is often used as a feature plant in Asian gardens. Our supply is extremely
limited now, but our small trees are heavy with dark red, showy fruit.
4. Saraca thaipengense: is an evergreen
treasure of a tree, maturing rather quickly at around 20 feet. It has a sprawling canopy,
often wider than it is tall. The new leaves come out in the shape of a horn that
unfolds, cascading 3 feet, in limp fashion. Usually, the new leaves are a pale mint
green that changes to a soft mustard rose before turning color again into its
mature emerald laceolate form. Flowers are borne on the trunk, on hardwood limbs,
as well as tips of branches. Enormous clusters of deep golden flowers appear
literally anytime, on mature trees. In nature, it is often found growing with
its roots very near a source of water but it flowers best after a dry spell. Consider
wind protection for the spectacular new leaf feature, and partial shade to encourage
rapid growth.
5. Stemmadenia galeotiana: originates in
tropical America. A multi-layered canopy up to 20 feet tall. It blooms from mid-April to
late Winter. When in full bloom, perfume fills the area with a soft, musky
sweetness. A massive profusion of flowers decks the branches, pure white against lacquered,
dark green leaves, and carpets the ground with fallen blossoms. They grow well in
full sun, as well as in semi-shade, and can even tolerate a little sea spray. They can
be maintained under 20 feet with pruning and shaping. Seed pods are golden in
color, about 4 inches long, horn-shaped, often in pairs.
6. Brownea grandiceps: is another tree from
our own hemisphere. Given time, plenty of water, rich soil, and other essentials,
the canopy can billow up to 30 feet. In our calcareous soil, we expect them to
crest at about 20 feet. Flowers, produced October through January, are 8-10 inches
across in bouquet-form, along the hardwood stems, on the trunk, and at the
apex of the branches. The color is variable ranging from a soft, creamy
pink, to a lush carmine red, flecked and streaked with shades of blue and purple tones.
Even without flowers, it has a beauty of form. In flower, it is spectacular.
Most of these species from our collection were
planted in various South Florida gardens over the past five years, and are doing very well. Special trees deserve a special effort, and they will reward you
with special beauty.
