Particular orchid species have different requirements
depending on where they grow. Many species of orchid grow up tree trunks.
The orchid is not a parasite meaning it doesn't hurt the tree at all,
and other than stem-support takes nothing from the tree.
Since there are so many different types of orchid, it
is hard to describe them generally. Some orchids require lots of sun.
Some orchids only need an hour or two or direct sunlight each day.
Orchids have long been sought after by flower collectors.
Sadly, orchid species are becoming extinct faster than they can be described
and classified. Threats to orchids originate primarily from loss of
habitat and collecting.
