Ceanothus spinosus Nutt.
Redheart, Greenbark ceanothus, Red-heart mountain lilac
Rhamnaceae (Buckthorn Family)
USDA Symbol: CESP
This species is grown as an attractive ornamental and screen along roadsides and is useful for erosion control. However, old plants become irregular, sprawling, and untidy with the dried remains of the capsules. It is called Redheart because of the dark red wood, which makes good fuel. The shrubs are spiny, drought-resistant and sprout from stumps but are killed back in cold winters. The foliage of this and related species is browsed by deer and elk.
