Ceanothus arboreus, with the common names feltleaf ceanothus, island ceanothus, and island mountain lilac, is a species of Ceanothus shrub in California. [2] [3]
Distribution
The plant is endemic to coastal southern California, primarily on three of the Channel Islands: Santa Cruz Island, Santa Rosa Island, and Santa Catalina Island. [2] [4]
It is found on slopes in coastal sage scrub and chaparral habitats. [2]
Description
Ceanothus arboreus is a spreading bush growing up to 12–36 feet (3.7–11.0 m) in height. [4] It has glossy dark green leaves which are leathery or felt-like on their undersides. [4]
Its showy bright blue flowers grow in plentiful panicles, or bunches, of tiny five-lobed blossoms. [4] Some varieties and cultivars have light, powder blue blooms, and others bear darker blue flowers. The bloom period is February to April. [2]
The fruits are three-lobed, triangular capsules. [4]
Cultivation
'Ceanothus arboreus is cultivated as an ornamental plant for use in drought tolerant and wildlife gardens and natural landscaping projects. [5] [6] Butterflies like the flowers and the quail eat the seeds. [5]
Cultivars
Numerous cultivars have been selected for garden use, including:
- Ceanothus arboreus 'Cliff Schmidt' — more compact habit and deeper blue flowers. [7]
- Ceanothus arboreus 'Owlswood Blue'. [8]
- Ceanothus arboreus 'Powder Blue' — Powder Blue Ceanothus, Compact Feltleaf Ceanothus. [9][10] [11]
- Ceanothus arboreus 'Skylark'
- Ceanothus arboreus 'Trewithen Blue' — very dark blue flowered form from the Channel Islands. [12] It has received the Royal Horticultural Society's Award of Garden Merit.[13]
