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.

Description[edit]

Ceanothus arboreus is a spreading bush growing up to 6 metres (20 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. The fruits are three-lobed, triangular capsules.

Cultivation[edit]

'Ceanothus arboreus is cultivated as an ornamental plant. As a native of dry California, the plant is drought-tolerant and may be found in chaparral ecosystems.
