- From California Native Plants, Theodore Payne's 1941 catalog: "A large dense growing shrub 8 to 12 feet high with dark green foliage. The flowers are bright blue to deep blue, produced in great profusion from March to May. This was the first of the California lilacs to be brought under cultivation and is one of the most valuable for general purposes. Very attractive as single specimens, in groups or for planting against a wall. Very easy to grow and will stand ordinary garden culture. Gallon cans, 50c; 5 gallon cans, $1.75."
