Ceanothus spinosus, with the common names greenbark and redheart, is a species of Ceanothus . [1] It is native to southern California and northern Baja California, where it grows in the scrub and chaparral of the coastal mountain ranges.
Ceanothus spinosus is a large treelike shrub approaching 6 metres (20 ft) in maximum height. [1]
Leaves have a single main vein rising from the leaf base. [1] The thick, firm evergreen leaves are hairless, oval, and up to an inch wide, with smooth margins. [1]
The bark is smooth and olive green, giving rise to its common name. [1] The stem is a rough-barked trunk near the base.[ citation needed ] Branches are stiff and sharp, or spiny, at the tips. [1] "Ceanothus" means "spiny plant" in Greek, and the species name, "spinosus", means that it is even more spiny. [1]
The stipules (small leaf-like structures at the base of the leaf stem) are thin and fall off early. [1]
The shrub blooms in inflorescences up to 15 centimeters long filled with clusters of white to pale blue flowers. [1] The fruit is a smooth, round capsule about half a centimeter wide containing three lobes.
Fruits do not have horns, as do some other members of the genus. [1]
It blooms from February to May. [1]
