What do these mean?



Hearst’s ceanothus is a narrow endemic found only in coastal portions of southern San Luis Obispo County. Branches of only a few inches in height quickly radiate out from the center in a star pattern. With age the foliage mounds to no more than a foot in height. The leaves are small, shiny, dark green ovals with a wavy edges and a warty surface reminiscent of Ceanothus papillosus. If planted behind small boulders or retaining walls, its attractive features may be appreciated as it spills over these. As with most coastal ceanothus, Hearst’s ceanothus requires some protection from the afternoon sun if grown away from the coast. Although tolerant of most soil types, it seems to thrive and be most long-lived in well-draining soil. In Santa Clara County (Sunset zone 15), plants of this species are a good choice for a shady setting and seem to appreciate an occasional light overhead watering. Hearst’s ceanothus has a reputation for being difficult and short-lived, but it is well worth the effort.
