CALIFORNIA LILAC 
The Ceanothi or California Lilacs are among the most prized 
of our native shrubs, having beautiful fragrant flowers and 
attractive evergreen foliage. The genus contains many differ- 
ent habits of growth, types of foliage and color of flowers. 
Some are tall shrubs, others of medium height, while others 
again are comparatively dwarf and still others mere ground 
covers. The colors range from white to pale blue, light blue, 
lavender, bright blue, deep blue and very dark blue. The 
flowering season is from December to June and they can he 
used effectively in a great variety of ways. A little pruning 
when young is generally beneficial and helps to build up more 
shapely plants. Summer watering in general is unnecessary 
ee eds rable after the plants have once become well es- 
ablished.

tree 12 to 25 feet high. Leaves large, broadly ovate, generally

Flowering period February to April. From the islands off the 
coast of Southern California. A very desirable shrub for tall 
screen planting, can also be trained to a single stem and 
grown as a tree. Gallon cans, $1.00. 
*Ceanothus arboreus hybridus. ’Hybrid Island Lilac.” A nat- 
ural hybrid between C. arboreus and C. spinosus. Of rapid 
growth with large glossy green foliage and immense trusses

The flowers are produced in immense spikes and are the rich- 
est shade of dark blue, appearing in May and June after the
