MANUAL OF GARDENING 



Sumac, smooth and hairy, R. glabra"^ and R. typhina.'^ 



Useful for the borders of large groups and belts. They may be cut down every 

 year and allowed to sprout (as in Fig. 50). The young tops are handsomest. 

 R. glabra is the finer species for this purpose. They usuallj^ grow 10-15 ft. 

 tall. 



Osbeck's sumac, R. semialata var. Osbeckii. 



Strong bush, 10-20 ft., with leaf-rachis strongly winged, the foliage 

 pinnately compound. 



Flowering, or fragrant currant, Ribes aureum.^X 



Well known and popular, for its sweet-scented yellow flowers in May; 5- 

 8 ft. 



Red-flowering currant, R. sanguineum.'^ 



Flowers red and attractive; 5-6 ft. 

 a hybrid between R. sanginneian and R. 



Rosa rugosa. 



R. Gordonianum, recommendable, is 

 au7'eum. 



Rose acacia, Ro- 

 hinia hispida.^X 

 >^ Very showy in 



bloom; 8-10 ft. 



Roses, Rosa, va- 

 rious species. 



Hardy roses are 

 not alwaj's desir- 

 able for the lawn. 

 For general lawn 

 purposes the older 

 sorts, single or 

 semi-double, and which do not require high culture, 

 are to be preferred. It is not intended to include 

 here the common garden roses; see Chapter VIII for 

 these. It is much to be desired that the wild roses 

 receive more attention from planters. Attention has 

 been too exclusively taken by the highly improved 

 garden roses. 



Japanese rose, Rosa rugosa.X 



Most excellent for lawn planting, as the foliage is 

 thick and not attacked by insects (Fig. 263) ; white 

 and pink flowered forms; 4-6 ft. 



Wild swamp rose, R. Carolina.'^ 

 5-8 ft.
