Seacliff Lilac. (Ceanothus thyrsiflorus griseus.) In Santa Bar- 
bara Botanic Garden. One of the best of the California Lilacs 
for general use. 
*Ceanothus crassifolius, “Thick Leaved Lilac.” A much branched 
shrub of rather rigid growth 5 to 12 feet high. Leaves thick, oppo- 
site, dull green, white tomentose on under side. Flowers white; 
blooms from December to March. Gallon cans, 60c. 
*Ceanothus cuneatus, “Buck Brush Lilac.” A dense branching 
shrub 5 to 12 feet high, with small dark green oblong leaves and 
white flowers. Flowering period February to April. Very attractive 
when not in bloom as a foliage shrub. Gallon cans, 50c. 
*Ceanothus cyaneus, “San Diego Lilac.” A rare species from San 
Diego County, introduced into cultivation by us in 1922 and now 
the most popular of the California Wild Lilacs. The shrubs grow 
6 to 12 feet high with rich glossy green foliage. The flowers are 
produced in immense spikes and are the richest shade of dark blue, 
appearing in May and June after the other species are over. The 
blossoms are produced in such profusion that the plant is a mass of 
bloom. This shrub is naturally of rather tall sparse growth, but by 
pruning back severely when young it can be made into a well 
shaped bush. It requires good drainage and thrives best in disin- 
eae granite or gravelly soil. Gallon cans, 50c; 5 gallon cans,

*Ceanothus cyaneus hybridus, “Hybrid San Diego Lilac.’ A nat- 
ural hybrid which appeared in our nursery last year among a lot of 
seedlings of C. cyaneus. Probably a cross between C. cyaneus and 
C. arboreus. The plants are of more spreading habit than C. cyaneus 
and have larger leaves. The flower spikes are large and very similar 
to C. cyaneus, possibly a shade lighter in color. Appears to be a 
very vigorous grower and may be easier to grow than the parent. 
Gallon cans, 75c. 
*Ceanothus divaricatus (C. leucodermis) “Spreading Lilac.” A 
spreading bush 5 to 12 feet high with somewhat arching branches 
and glaucous stems and foliage. Flowers in medium sized spikes, 
pale smoky blue, sometimes white. Flowering period March to May. 
Found in foothills and mountains up to 5,000 feet elevation. Gallon 
cans, 60c. 
Ceanothus foliosus, ‘““Wavyleaf Lilac.” Low spreading shrub usu- 
ally 1 to 3 feet high, but sometimes growing erect to 8 feet. The 
leaves are small, rich dark green and look as though they had been 
varnished. Flowers bright blue to light blue. Flowering period March 
to May. This is one of the most attractive of the wild lilacs both
