Ceanothus 'Concha' (California Lilac)

California Lilac 'Concha', Ceanothus azureus 'Concha'


Regarded as one of the best California Lilacs for gardens, award-winner Ceanothus 'Concha' is a dense, evergreen shrub noted for its abundant clusters of deep blue flowers in late spring and early summer. Opening from reddish purple buds, the flowers are so profuse that they literally cover the bush, transforming the plant in an explosion of blue. The blooms are borne on gracefully ascending, arching branches clad with small, dark green leaves. Ignored by hungry deer, this pretty shrub is a real magnet for birds, butterflies and hummingbirds. A glorious and reliable Californian Lilac.
