Cordia boissieri: Texas Olive1

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean 2


Texas olive is a native North American evergreen tree which reaches 20-feet in height with a 10- to 15-foot spread. 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 flowers appear year-round, if enough rainfall or irrigation is available. Otherwise, the 3-inch-wide, trumpet-shaped, white blossoms with yellow throats will appear from late spring to early summer. The olive-like, white fruits that are produced have a sweet flesh relished by birds and other wildlife and, although edible to man, should not be eaten in quantities.

Use and Management

This is a versatile plant adapted for use as a specimen tree or as an accent in a shrub border. Showy, year-round flowers make it suitable for placing in a lawn area as a free-standing specimen. It can be planted in an above-ground container and kept looking nice for a number of years when it is carefully maintained.

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, Texas olive will lose its leaves in a severe frost. This is the cold-hardy relative of Cordia sebestena that is very sensitive to the cold.

Propagation is by seeds and air-layering.


No pests are of major concern.


No diseases are of major concern.
