attractive evergreen foliage. The genus contains many differ- 
ent habits of growth, types of foliage and color of flowers.

again are comparatively dwarf and still others mere ground

covers. The colors range from white to pale blue, light blue, 
flowering season is from December to June and they can be 
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 in unnecessary 
and undesirable after the plants have once become well es- 
tablished.

tree 12 to 25 feet high. Leaves large, broadly ovate, generally 
2 to 3 inches long, dull green, white tomentose on the under 
side. Flowers in large spikes, lavender blue and very fragrant.

of lavender blue flowers. Very free blooming and delightfully 
fragrant. In massed plantings it creates a veritable cloud of 
blue. Flowering period February to April. Gallon cans, $1.00.

San Diego County, introduced into cultivation by us in 1922

shrubs grow 6 to 12 feet high with rich glossy green foliage. 
The flowers are produced in immense spikes and are the rich-
