California Lilac 'Trewithen Blue'
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. This pretty shrub is prized by birds, butterflies and hummingbirds. A great addition to the landscape.
