feeder and strong grower and must be watched or it will 
monopolize the border. In height it runs from 8 to 12 feet. 
Viburnum.—To this genus belong the snowballs, the 
choicest of the white-flowering shrubs. They make beautiful 
specimens because the flowers are well set off against the in- 
tense dark green of the foliage. One of the best varieties 
is V. dentatum, or arrow-wood, with its greenish white 
flowers followed by dark blue berries in the fall. The foliage 
is heart-shaped and turns purplish late in the season: This 
shrub blooms in May, as ne all the viburnums, and is 6 to 
8 feet high. V. lantana has large clusters of white flowers 
followed by red berries and the foliage does not shed until 
very late. It grows to be about 8 to 10 feet tall. About the 
, same height is V. Lentago, or sheepberry, with its very frag- 
rant creamy white flowers. Viburnum Opulus is called the 
high bush cranberry, because of the cranberry-like berries 
which are produced in late summer and hang on until after 
frost. The flowers of this species are also very attractive. 
Its sterile variety, V. Opulus sterilis, is the common snow- 
ball and needs no comment. V. plicatum, known as the 
Japanese snowball, is very seldom grown in this country, 
but deserves to be better known. In height it is about the 
same as in the | etree varieties, but the flowers are in 
larger heads and have the advantage of a —— 
period. V. acerifoliwm, the maple-leaved viburnum, and V. 
tomentosum are varieties having the same desirable qualities 
as the others but are not as tall, being only about 6 to 8 feet 
in height. This particular genus of plants affords great satis- 
faction to the plant lover and some of the species should be 
in every border. 
Xanthoceras sorbifolia——The Chinese chestnut is a beauti- 
ful slow-growing shrub with creamy white flowers blooming 
in St. Louis in ee or May. It should prove a fine sub- 
ject for massing, although its slow growth will more probably 
cause it to be used for single specimens. 
Baccharis halimifolia or Groundsel Tree.—This is a wood: 
shrub of the yg cade group. The flowers are avian 
white and do not bloom until September, while the seed pods 
are attractive up to frost. It is not a very showy plant, al- 
though growing from 6 to 8 feet in height. 
Cornus.—The cornus, or flowering dogwood, blooms in 
June, producing grayish white flowers which are very attrac- _ 
tive against the dark background of the foliage leaves. The 
flowers are followed by beautiful fruit clusters and the bark 
adds a bit of color in winter time. C. alternifolia, C. panicu- 
lata, and C. sanguinea are three varieties which grow from
