6 to 8 feet high; while-G.- sericea grows-from 3 to 6 feet in 
height. C. florida, mentioned under trees in the last number 
of the Butietin, might be classed as a shrub during the 
first few years of its growth. 
Deutzia.—The deutzias are of Japanese origin but have 
been much improved by the breeder since their importation. 
The flowers are mostly white, although a few varieties have 
a pinkish tinge when in bud. D. candidissima, D. gracilis, 
D. Lemoinei, D. crenata, and D. scabra are the best of the 
white-flowered deutzias. D. gracilis is a dwarf species from 
two to three feet high, while the others run from 6 to 8 feet. 
D. crenata fi. pl., D. crenata Wateret, D. “Pride of Rochester,” 
and D. rosea plena are some of the pink-flowered varieties. 
Because of their vigorous growth and the beauty of their 
flowers they should be used in all borders where floral effect 
is desired in June or July. 
Diervilla.—The diervilla, or weigelia, is vigorous in growth 
and is one of the best shrubs for St. Louis. It flowers in mid- 
summer and the foliage is a rich, deep n. The white 
varieties are D. amabilis alba and D. candida, both of which 
bloom in July and attain a height of 6 to 8 feet. They 
not only make very desirable plants for the shrubbery masses 
but also het i as single specimens. A single year’s growth 
of the diervilla in the border will help more than any other 
shrub to give finish and an appearance of solidity. 
Hydrangea.—H. paniculata and H. paniculata grandiflora 
are very desirable plants where medium height is desired, 
both usually reaching 6 to 8 feet. The size of the blooms de- 
pends very largely upon the method of pruning. In the 
winter all new growths from the previous season should be 
cut back to one or two eyes or buds; then with the use of 
Tapes of manure in the soil, large flower clusters will result. 
time shrubs so treated will me tree-like and single 
specimens sometimes attain a height of 8 to 10 feet with a 
spread of 10 to 15 feet. H. arborescens and its variety 
grandiflora are more dwarf, usually growing to about 4 to 6 
feet high. The flower clusters of the large-flowered variety 
are particularly striking and have given rise to the names 
“Snowball Hydrangea” and “Hills of Snow.” These seem 
to do better in a rather damp and shady location, although 
different conditions do not apparently affect its beauty. 
There is also an oak-leaved hydrangea from 3 to 6 feet tall 
called H. quercifolia which, though not so conspicuous in 
flower, is very attractive. 
Lonicera.—L. tatarica alba, sometimes called Tartarian 
honeysuckle, is a strong, vigorous shrub attaining a height
