A tall evergreen shrub with gray green leaves  and light gray to white bark. The flowers range from light blue to white. This lilac requires full sun and well-draining soil. It is most often used in revegetation projects  but would also be a good choice for hot  dry inland sites transitioning from more formal landscaping to the chaparral. It is unlikely to be happy in coastal settings  as it originates from the dry rocky slopes of the Sierra Nevada  and in mountains of southern California.
