Ceanothus Arboreus

What is the plant

Ceanothus arboreus is a species of shrub endemic to California, especially to the Channel Islands. It is known commonly as feltleaf ceanothus. It is a species of what are sometimes called California lilacs, and may be referred to as the California mountain lilac or island mountain lilac. It is one of the tallest of the genus, growing up to 25-30 ft. in height, bearing glossy dark green leaves which are leathery or felt-like on their undersides. It is sometimes planted as a fast-growing ornamental for its showy bright blue flowers, which grow in plentiful panicles, or bunches, of tiny five-lobed blossoms. Some varieties and cultivars have light, powder blue blooms, and others bear darker blue flowers.

How to Care for the Plant

Water
As with all plants known for their drought resistance, they need masses of water when first planted but once established, never again.
Pruning
Prune these immediately after flowering, using secateurs to cut back long, flowered shoots by one-third to a half. If needed, you can lightly trim these plants again in late summer.
Fertilizer
Fertilize with manure or compost in spring or fall.
