Magnificent, award-winner Ceanothus arboreus 'Trewithen Blue' is a large, spreading, evergreen shrub noted for its abundant clusters, 5 in. long (12 cm), of fragrant, deep blue flowers in late spring and early summer. The flowers are so profuse that they literally cover the bush, creating a breathtaking floral display. The blooms are borne on gracefully arching branches clad with broadly oval, shiny, emerald green leaves. Usually ignored by deer, this pretty shrub is prized by birds, butterflies and hummingbirds. A great addition to the landscape.
