Heliconias
are remarkable plants, not only for the beauty of their flowers,
but also for the fact that they are so mysterious -- so little
is known about them, their cultivation and care. Anyone travelling
in the tropics will marvel at these large, eye-catching plants
when they are in bloom. Although these large tropical flowers
are natives to only Central and South America and some islands
of the South Pacific, their easy cultivation and spectacular presence
have made them favorite garden subjects throughout the world.
They have become increasingly popular as decorative flowers, especially
in those regions where they cannot be grown in the garden.
HABITATS
Most
species of heliconias can be found in moist or wet regions, but
some are found in seasonally dry areas. Although Heliconias flourish
in the humid lowland tropics at elevations below 1500 feet, surprisingly,
the greatest number of species are found in middle elevation rain
and cloud forest habitats. The most remarkable members of the
genus inhabit open sites in secondary growth along roads, riverbanks
and in patches of light in the forest.
POLINATORS
In the
American Tropics, hummingbirds are the exclusive polinators of red,
yellow , pink and orange heliconias while nectar feeding bats are
the polinators of green heliconias.
BOTANICAL
RELATIVES-TAXONOMY.
THE ORDER
ZINGIBERALES.
Heliconia
is the only genus in the plant family heliconiacea, which is a
member of a larger taxonomic category called the order Zingiberales.
There are several very obvious characteristics by which they can
be recognized, including large leaves and large, colorful, bracteate
inflorecences. Most taxonomists recognize eight separate families
in the zingiberales : Musacea (Bananas),Strelitziacea (Bird of
Paradise), Lowiacea, Heliconiacea (Heliconias), Zingiberacea (Gingers),
Costacea (Costus), Cannacea (Cannas) and Marantacea (Prayer Plants).
