One of the most remarkable
characteristics of the orchid family
is its adaptation to cross pollination,
a byproduct of insect activity.
Insects are attracted by a flower and
stimulated to satisfy one of the
ever-present dynamic urges of
nature: hunger and sex.
Most flowers of orchid species
provide either edible tissue or, nec-
tar as an attractant for visiting
insects. Upon leaving, the insect

which it carries to the stigmas of the
next flower visited.
After fertilization, seeds are pro-
duced. Orchid seeds are the small-
est of all the flowering plants. Seeds
are carried by the wind and rely on
a symbiotic relationship with a fun-
gus in the soil to germinate.
This seemingly haphazard pro-
cess has carried on for centuries. If
you are interested in growing
orchids, join the Orchid Society of
the Virgin Islands. For more infor-
