There are
several varieties, but the palm yucca is the most common, and
under favorable conditions attains to the proportions of a tree.
Fine specimens of yucca grow on the Mojave desert in California
that are large and numerous enough to form a straggling forest.
The tree consists of a light, spongy wood that grows as a single
stem or divides into two or more branches. Each branch is
crowned by a tuft of long, pointed leaves that grow in concentric
circles. As the new leaves unfold on top the old leaves are
crowded down and hang in loose folds about the stem like a
flounced skirt. When dry the leaves burn readily, and are
sometimes used for light and heat by lost or belated travelers.
White threads of a finer fiber are detached from the margins of
the leaves that are blown by the wind into a fluffy fleece, in
which the little birds love to nest.
A grove of yucca trees presents a grotesque appearance. If
indistinctly viewed in the hazy distance they are easily mistaken
for the plumed topknots of a band of prowling Apaches,
particularly if the imagination is active with the fear of an
Indian outbreak.
The wood of the yucca tree has a commercial value. It is cut
into thin sheets by machinery which are used for surgeon's
splints, hygienic insoles, tree protectors and calendars.
