|Evergreen small tree or large shrub. Many species have spiny, dark green, lustrous leaves and gray bark. Seedless red berries borne in profusion are attractive in winter. The species vary in when berries appear, color of berries and leaves, and whether the leaves have spines. Excellent specimen tree or durable screen. Should be protected from sun in hot, dry areas. Prefers acid soil. Male plants do not have berries as do some females. If berries are important, be sure to select a named variety noted for its berries.
