Woody
plants are
perennials (ie. trees and
shrubs) that retain their woody structure
permanently, but may lose their foliage
in seasonal climates.
Woody
= of wood. The
stems
(and roots) of woody plants, e.g., most
shrubs and
trees, are usually
covered with non-green bark, and enlarge in diameter by the accumulation
of annual layers of wood (secondary
xylem).
