Smooth Sumac in fruit (RHUS) 
RHUS — SUMAC 
Known to most of us for the brilliant coloring of 
the foliage in the fall, the Sumacs are useful for the 
shrub border or massed for naturalistic effects. The 
hardiness of the Sumacs will permit their use on dry 
sandy slopes. 
Rhus canadensis 
FRAGRANT SUMAC 
This low spreading shrub has its name from the pleasant 
aromatic odor given off when its foliage or bark is crushed. It 
is sometimes used for covering sandy knolls or rugged banks 
and is particularly harmonious in the border. The leaves, unlike 
those of the familiar Staghorn Sumac, are luxuriant green chang¬ 
ing to yellow, orange and scarlet in the fall. Landscape designers 
use it plentifully where a naturalistic effect is desired. 
Rhus cotinus 
SMOKETREE 
An old garden favorite, mostly because of the misty clouds 
of plume-like flowers borne in summer at a time when most other 
shrubs are least attractive. The handsome foliage adds its share 
to the plant's beauty. It likes plenty of sunshine and light, well 
drained soil. It reaches a spreading fifteen feet in height if given 
room. 
Rhus glabra 
SMOOTH SUMAC 
This plant, is a strong grower and suitable for creating 
naturalistic effects, it has green flowers in July, followed by large 
pointed heads of scarlet fruit in August and September. 
Rhus typhina 
STAGHORN SUMAC 
A widely planted and well known shrub of exquisite beauty, 
especially in fall when its large pointed heads of fruit clusters and 
highly colored, finely cut foliage make a brilliant showing. It 
grows to a height of 10 or 15 feet and makes no comolaint against 
the drier or less fertile soils. 
RIBES — CURRANT 
Ribes odoratum 
GOLDEN CURRANT 
The clove fragrance of the golden yellow tubular flowers 
in spring is enough reason for including this plant in the shrub 
border or along drives and walks. The flowers, which bloom after 
the Forsythias, are accompanied by a luxuriant growth of dainty 
green leaves. Pruning out all the three and four year old wood 
close to the ground keeps the shrub from outgrowing the space 
allowed for it. It usually grows about five feet high. 
ROBINIA — LOCUST 
Robinia hispida 
ROSE-ACACIA 
A highly decorative shrub of great beauty with graceful 
feathery-form leaves (rich in color) and drooping sweet pea-like 
blossoms. It reaches a height of about 10 feet which makes it a 
valuable border or screen plant. It grows vigorously and suckers 
freely, so that pruning is necessary to keep it in a restricted 
space. Light dry, unfertile soils do not restrict its growth. 
ROSA — ROSES 
Under this classification are the larger growing 
shrub type roses which are well adapted to border 
plantings. Garden rose varieties are fully described 
and illustrated in a separate section of this catalog. 
The flowers of shrub roses may be single or double 
and the color range is fully equal to that of the garden 
varieties. They are also considered much hardier.
