Ceanothus arboreus
Also called Catalina Mountain Lilac, Felt Leaf Ceanothus, Catalina Ceanothus, Island Ceanothus
Feltleaf ceanothus is a large, spreading evergreen shrub or small tree from the Channel Islands of California and Guadalupe Island, grown for its glossy leaves and blue spring flowers. It thrives in full sun with good drainage and very little summer water once established.
Ceanothus arboreus is a species of perennial shrub to small tree in the family Rhamnaceae, commonly known as the feltleaf ceanothus, island ceanothus, and island mountain lilac. It is the largest member of the California lilacs (the Ceanothus genus), and is characterized with glossy, dark green foliage that is adorned by pale blue to white flowers in bloom. It is endemic to the Channel Islands of California and Guadalupe Island in Mexico, only being re-discovered on Guadalupe Island after the elimination of feral goats.
'Ceanothus arboreus is cultivated as an ornamental plant for use in drought tolerant and wildlife gardens and natural landscaping projects. Butterflies like the flowers and the quail eat the seeds.
The plant is endemic to three of the Channel Islands of California: Santa Cruz Island, Santa Rosa Island, and Santa Catalina Island, and it is also found on Guadalupe Island in Mexico.
