This group consists of more than 400, quick-growing, tender, evergreen
trees and some shrubs native to Tasmania and Australia. These unique trees
can grow to gigantic proportions; some species can reach heights over 400
feet in their native habitats.
Eucalyptus trees, also popularly known as Gum trees because some species
exude a gum, are fragrant and normally pest-resistant. These trees have
leathery, smooth, lance-shaped leaves, which have a more rounded shape
when young. Their puffball-like flowers may be red or orange and are very
attractive to bees. They have no petals, but instead, numerous stamens
arising from a capsule-like calyx, which give them their fluffy appearance.
The attractive, colorful bark of the stems and trunks of the Eucalyptus
may be dappled in gray, green, russet, or cream and may peel in sheets.
Besides the decorative qualities of the trees, Eucalyptus are valued
for their timber, the important oils of the leaves and shoots, tannin,
which is taken from the bark of some varieties, and a resinous substance
known as kino.
