where they may be viewed from a distance. This is espe- 
cially true where many colors enter into the garden scheme. 
In combination with red, purple, or blue, yellow is very 
attractive, but care must be taken to choose the right shades 
in the combination. 
Elaeagnus angustifolia or Russian Olive.—The flowers of 
this species bloom in June and while not large are very num- 
erous and fragrant, and are followed by silvery-coated yel- 
low berries. This is a quick-growing shrub from 12 to 15 
feet high and is used chiefly for the silvery effect of the 
foliage. 
Caragana arborescens.—This is a hardy plant, commonl 
called the pea shrub, which thrives in almost any well- 
drained soil. The showy yellow flowers bloom in great pro- 
fusion in late spring and early summer. In height it varies 
from 8 to 10 feet. 
Forsythia or Golden Bell.—The forsythia is one of the best 
of the spring-flowering shrubs. As the flowers appear before 
the leaves on the wood of the previous year, pruning should 
be delayed until after the blooming done 9 This is, of 
course, true for any shrub that flowers on the wood of the 
previous season. The forsythias have both grace and beauty 
and combine excellent foliage with abundant flowers. The 
varieties, F. intermedia and F. viridissima, have an erect 
habit, while F’. suspensa and F’. suspensa fortunei are more 
drooping. The latter two with a little help can be used to 
cover very high walls, and when so grown are very beautiful. 
The upright varieties are from 6 to 8 feet in height, while the 
varieties of F. suspensa may grow under certain conditions 
as high as 10 to 12 feet. 
Ribes awrewm.—This is known as the Missouri currant. 
It is a rapid-growing shrub that is inclined to sucker badly 
but nevertheless is an admirable plant for the edge of the 
shrubbery border. Its habit of spreading tends to show to 
advantage the small yellow flowers which come in the early 
spring. In height the plant ranges from 4 to 6 feet. 
Rhus aromatica—The sweet-scented sumac is a much 
branched, spreading shrub usually 2 to 4 feet tall. It makes 
a beautiful plant for low corners of shrubbery masses with 
its rich, dark green foliage. The flowers which precede the 
leaves in the early spring are yellow, produced in short spikes 
or clusters along the branches. 
Kerria japonica fl. pl.—This is a low-growing shrub, some- 
times called the dedi Riveter, which makes a good edge for 
high shrubbery. It blooms nearly all summer, the flowers
