Ceanothus arboreus aka Feltleaf Ceanothus

Ceanothus arboreus, also known as the feltleaf ceanothus, island ceanothus, or island mountain lilac, is a species of perennial shrub to small tree in the Rhamnaceae family. Endemic to the Channel Islands of California and Guadalupe Island in Mexico, it was recently rediscovered on Guadalupe Island after the eradication of feral goats. This large and vigorous evergreen shrub can reach heights of up to 6m. It features glossy, dark green foliage with leathery or felt-like undersides and produces panicles of slightly fragrant, deep blue flowers that can grow up to 12cm in length. With its showy and abundant blooms, Ceanothus arboreus is often planted as a fast-growing ornamental, and various varieties and cultivars offer a range of bright and powder blue flower colors.
