Dark Star Mountain Lilac
Ceanothus Dark Star
  
About Dark Star Mountain Lilac (Ceanothus Dark Star) 13 Nurseries Carry This Plant Hybrid of Ceanothus impressus and Ceanothus papillosus var. roweanus. Ceanothus 'Dark Star' is a compact shrub growing to about 6 feet tall by 8 feet wide. The leaves are small, rough-textured and dark green. In spring the dark cobalt-blue flower clusters with yellow stamens give the impression of a starry night (hence the name). Plant in full sun in well draining soil. 'Dark star' requires little or no water in summer. It is hardy to 5 degrees F. This Ceanothus impressus hybrid is one of the showiest of the California Lilacs, but has a reputation for being fussy in inland gardens. We have it planted here inland and have been very happy with its performance.

Hybrid; origin = seedling (1968) C. impressus x C. papillosus var. roweanus?; intro Ken Taylor Nursery 1971 Tolerates almost any soil type. Prefers sun in coastal sites, and sun or part shade in inland sites. Introduced by Ken Taylor Nursery in 1971. Believed to be a C. impressus x papillosus hybrid.
