Texas Olive is a native North American evergreen tree which reaches 20′ in height with a 10-15′ spread and is best used as a small specimen tree. It is slow growing and has a rounded canopy of moderate density. This small tree is very rarely found and is even reportedly close to extinction. The silvery green leaves have a velvety texture and the showy, white, petunia-like flowers appear year-round, if enough rainfall or irrigation is available. Otherwise, the three-inch-wide, trumpet-shaped, white blossoms with yellow throats will appear from late spring to early summer. Texas olive should be grown in full sun or partial shade on well-drained soils and is highly drought tolerant. Although hardy to about 20°F, it will lose its leaves in a severe frost. The olive-like fruits, ½-1″, which are produced have a sweet flesh relished by birds and other wildlife and, although edible to man, should not be eaten in quantities.
