ROSA CAROLINA PASTURE ROSE 



A low, suckering shrub about one yard in height, with pink flowers about 

 two inches across. For bank planting and ground cover. 



ROSA eglanteria (R. rubiginosa) Sweetbrier 



A tall (eight to ten foot), thorny bush which builds up into a compact shrub, 

 with two-inch pink flowers in small clusters along its slender branches, followed 

 by round, orange or scarlet fruits. It makes a fine specimen plant if given 

 ample space, or may be used for hedges or barriers. Like many other species 

 of Roses, it is a parent of numerous hybrids. 



Rosa tallica FRENCH ROSE 



Full, upright shrub to some four feet, with thorny stems and single, dark 

 pink or crimson flowers two to three inches across, and brick-red fruits. It 

 is one of the parents of the "Hybrid Perpetuals." 



"Hybrid perpetual" Roses, if given the right sort of pruning, can be of 

 value in shrub borders. These selections are made from among the bushy- 

 growing varieties, "baroness Rothschild", double, light-pink flowers; 

 "BARONNE prevost", large, full, fragrant, rose-colored; "HORACE vernet", 

 large, double, high-centered, crimson; "jules margottin", double, carmine, 

 slightly fragrant; "louis van houtte", large, fragrant, crimson-maroon; 

 "Suzanne-marie rodocanachi", free-flowering, rosy-cerise. 



X ROSE HARISONII Harison's Yellow 



An old-time hybrid which has been a favorite shrub or hedge plant for more 

 than a hundred years. It has bright yellow, semi-double flowers in June and 

 black fruits. The plant suckers freely, and is usually seen as a four- to six- 

 foot shrub which is hardier than "Persian Yellow." 



ROSA HUGONIS 



A large (six to eight feet if allowed to grow naturally), small-leaved, spreading 

 and drooping shrub with prickly reddish stems and single, bright yellow flowers 

 freely borne in May. It needs intelligently directed pruning if it is to be kept 

 as a compact individual specimen. 



ROSA NITIDA BRISTLY ROSE 



A small plant of some eighteen inches in height, with shining foliage and 

 single pink flowers up to two inches across. Useful in the large rock garden 

 or in masses as ground cover on sunny but not too dry slopes. 



X "POLYANTHA" ROSES 



A group of hybrids of which the tall (two to three feet), large-flowering sorts 

 also offer material for shrub use. "KIRSTEN poulsen", large, single, light 

 red, everblooming; "marie pavic", white with pink center; "MRS. 

 R. M. FINCH", rose-pink, two-inch flowers, everblooming; "SALMON 

 spray", salmon-pink, tall-growing, long-stemmed. 



ROSA PRIMULA (R. Ecae of gardens) 



Upright shrub to some six feet in height. Earliest species to bloom, with 

 yellowish-white flowers followed by red fruit. Young foliage aromatic, and 

 stems interesting in winter. 



ROSA ROULETTII 



A dwarf, hardy, rock-garden form which will start showing its pleasant 

 reddish-pink flowers in its first season from cuttings, and will eventually build 

 up into a compact bush some twelve to fifteen inches through. It seldom 

 sets seed in cultivation. Much stock in the trade under this name is really
