Synonym(s): Ceanothus greggii ssp. vestitus, Ceanothus vestitus
USDA Symbol: CEGRV
Desert ceanothus is an erect, rigidly branched, half-evergreen shrub from 3-6 1/2 ft. tall. Leaves are small and leathery - grayish-green above, gray beneath. The showy flower clusters are composed of small, creamy-white to bluish flowers.
There are dozens of species of Ceanothus in North America. A few reach tree size, but most are shrubs and the majority occur in the West.
The species name “greggii” was named for Josiah Gregg, (1806-1850). He was born in Overton County, Tennessee. In the summer of 1841 and again in the winter of 1841-42 he traveled through Texas, up the Red River valley, and later from Galveston to Austin and by way of Nacogdoches to Arkansas. He took note of Texas geology, trees, prevalent attitudes, and politics. At the same time, Gregg began compiling his travel notes into a readable manuscript. His “Commerce of the Prairies”, which came out in two volumes in 1844, was an immediate success. In 1848 he joined a botanical expedition to western Mexico and California, during which he corresponded with and sent specimens to the eminent botanist George Engelman in St. Louis. Subsequently, the American Botanical Society added the Latin name “greggii” in his honor to twenty-three species of plants. Gregg died on February 25, 1850, as a result of a fall from his horse.

PropagationSeed Collection: Collect seeds in late summer and early fall. Because dry capsules disperse their seed abruptly with a sudden ejection, it may be necessary to tie cloth bags around the clusters of capsules to catch the seeds.
Seed Treatment: Scarification may be necessary and can be accomplished by soaking the seeds in hot water (180-200 degrees). Soak in cooling water 24 hours. Stratify all seeds for 60-90 days at 41 degrees.
Commercially Avail: yes
