Evergreen, name applied to any plant that retains its foliage through two or more consecutive seasons. In contrast to deciduous plants, which shed their leaves seasonally, evergreens retain their foliage anywhere from 1 to 18 years. Many common varieties, such as spruce, fir, and other members of the pine family, have needle-shaped foliage, but most evergreens are broad-leaved. Some shrubs and trees are both deciduous and evergreen, depending on where they are grown. Many species are valuable for their timber, while mistletoe and other evergreen foliage is popular as Christmas decoration.
