evergreen leaves. The Rhododendron contains some 850 species, the
majority of which are cultivated. The natural distribution of
Rhododendron is interesting and unexplained. About 700 species occur in
the Himalayas of northeastern India, Burma, and southwestern China, and
an additional 300 or so species occur in New Guinea. They exhibit great
variety in size, habit, and flower color, ranging from small,
ground-hugging shrubs to small trees and from white to pink,
dark-purple, or yellow flowers. |
