ROSA VIRGINIANA 



A free-blooming, six-foot shrub with shining foliage which turns bright 

 yellow in autumn, and relatively late, two-inch, single, pink flowers in June 

 followed by bright red fruits. 



Rosa Webblana 



Shrub of some six feet in height with thin stems bearing yellow prickles. 

 The pale-pink, two-inch flowers are followed by bright red fruits. Useful in 

 shrub borders. 



ROSA WIGHURAIANA Memorial Rose 



The type plant has long, running branches which, when given no support, 

 advance to cover the ground with mat-like, partially evergreen foliage. Its 

 fragrant white flowers are borne in clusters. It is parent to numerous hybrids 

 of which the following are to be recommended as ground-cover plants for sunny 

 slopes and banks, because of healthy, mildew-resistant foliage. "ALBERIC 

 BARBIER" with glossy foliage and fragrant, creamy-white flowers; "AVI- 

 ATEUR BLERIOT" with saffron buds and fragrant flowers fading to white; 

 "EVERGREEN GEM", a prostrate creeping plant with almost evergreen 

 foliage and pale yellow, single flowers, which does well in poor soil; "FRAN- 

 COIS POISSON" with dark, glossy, almost evergreen foliage on a com- 

 pletely prostrate plant and flowers double white or pale yellow; "SANDERS 

 WHITE", rated as one of the best white climbing Roses for any purpose. Its 

 pure-white, double flowers and disease-resistant foliage make it adaptable for 

 bank planting. 



Rubus Cockbumianus (R. Giraldianus) 



A spreading, flopping Raspberry of value in wild gardening because of winter 

 interest of its whitish stems. It associates itself well with boulders in open 

 places in dark, wooded areas. 



RUBUS DELICIOSUS Boulder Raspberry 



A rather strong-growing, rampant plant with arching branches which some- 

 times become nine feet in length. Its white, late-spring flowers are similar 

 to those of Rosa spinosissima var. altaica. Like the native Raspberry, it can 

 be used in rocky places. 



Rubus odoratus FLOWERING RASPBERRY 



As seen in cultivation, this native plant is usually a yard-high, upright- 

 stemmed, coarse, deciduous shrub with purplish flowers and a bothersome 

 habit of rapid spread by suckers. Not suitable for the garden but well adapted 

 to broad, wild situations in partial shade. 



Russian Olive — See Elaeagnus 



St. Johnswort — See Hypericum 



Sails alba var. vitellina GOLDEN WlLLOW 



A tall, spreading Willow which is of garden value only because of the winter 

 effect of its yellow branchlets. 



Sallx babylonlca BABYLON WEEPING WlLLOW 



This is the most common and the least hardy of several often-confused 

 Weeping Willows. In aspect it has greenish or purplish branches and some- 

 what upright main stems. Like most Willows, this species will thrive in far 

 drier soil than is generally supposed. Var. crispa is an oddity on which all 

 leaves are curled.
