WOODY PLANTS FOR NEW ENGLAND 59 



Rosa chinensis var. minima (R. Lawrenciana) which grows more rapidly, has 

 a poorer flower color, sets seed freely, and is otherwise less desirable. R. Roulettii, 

 too, will, after study, probably be classed as a form of Rosa chinensis. 



Rosa rubrifolia RED-LEAF Rose 



A stout, reddish-branched, vase-shaped, six-foot, sparse-blooming plant 

 with reddish leaves and relatively small, bright red flowers. As seen in culti- 

 vation, this plant does not branch freely from the bottom and is not suitable 

 for specimen planting. 



ROSA RUGOSA 



A thick-stemmed, prickly shrub which at maturity becomes some six feet 

 or more in height. It displays rough, leathery, shining foliage and, in nature, 

 a variation in color of the large, all-season, single flowers from purple to white. 

 It has large, showy red or orange, persistent hips in autumn. Satisfactory for 

 informal hedges, roadside, or seashore plantings. It has numerous botanical 

 forms, such as var. plena, double purple flowers and var. albo-plena with 

 double white flowers, and is also the parent of many garden hybrids. Many 

 hybrids retain the aspect of the type plant but vary in floral characters, such 

 as "NEW CENTURY", large, double, flesh pink; "NOVA ZEMBLA", 

 large, white; "ROSE A PARFUM DE L'HAY", double, dark crim- 

 son; "SARAH VAN FLEET", rose-pink, fragrant, everblooming; "SIR 

 THOMAS LIPTON", white; and "STERN VON PRAG", large, double red. 



Another group of hybrids of a less rugosa-like aspect includes "AGNES", 

 fragrant amber-gold flowers; "AMELIE GRAVEREAUX", double, dark 

 purplish-red; "DR. ECKENER", semi-double, coppery-rose, and golden- 

 yellow; "SCHNEEZWERG", semi-double, snow-white flowers with center 

 of golden stamens throughout the whole season — a fine, hardy shrub with 

 dark-green, disease-resistant foliage; "VANGUARD", large, double, orange- 

 salmon. 



Another worth-while group has all-season bloom of small, fringed flowers in 

 clusters on a type-like plant — "F. J. GROOTENDORST", bright red; 

 "PINK GROOTENDORST", light shell-pink. 



There are two trailing rugosa hybrids of value for covering slopes or banks; 

 "MAX GRAF", with handsome foliage and sprays of large, single, pink 

 flowers, rated as the best rose variety for ground cover; and x R. Pauiu (R. 

 rugosa var. repens alba), with white flowers and stems up to fifteen feet long. 

 Will grow in any soil. 



rosa setigera Prairie Rose 



A pale-leaved American climbing Rose of considerable vigor, with two-inch, 

 single, pink flowers in July. If used against boulders or on steep pond banks, 

 this plant with its upward and outward spread and late-flowering habit can 

 pile up pleasing natural effects in roadside or wild-garden plantings. 



X ROSA, "SKYROCKET" 



Because of its straight, upright habit, medium-sized, all-season red flowers, 

 and showy, somewhat persistent autumn flowers, this garden variety offers 

 an outstanding example of the informal planting possibilities of several of the 

 newer everblooming, climbing roses. 



ROSA SPINOSISSIMA var. ALTAICA Altai ROSE 



For garden usefulness, this Rose may be considered as a single, white- 

 flowering counterpart of R. Harisonii, to which it is related. It builds up into 

 the same sort of symmetrical, sucker-spreading bush and has similar black 

 fruits.
