HARDY ORNAMENTAL TREES AND SHRUBS. 



319 



R. moschata {R. Brunoni). — A useful, vigorous climber; 

 flowers yellowish-white. Asia Minor, &c, 1596. 



R. multifiora {R. polyantha). — A very distinct Rose, re- 

 markable for the small size of its white or pink flowers, 

 which scarcely exceeds that of the double - flowered 

 Bramble, Crimson Rambler (fig. 391), a recent intro- 

 duction from Japan, is a form of this, but is a stronger 

 grower; the flowers are larger, double, and of a rich bright- 

 crimson. China and Japan, 1822. 



R. pomifera. — A sturdy shrub worth growing for the 

 beauty of its large, bristly, deep-red fruits. Europe. 



R. rubiginosa, Sweet-Brier. — This native Rose should 

 find a place in every garden, on account of the refreshing 

 fragrance exhaled from the glands of its leaves. The 

 flowers are pink. A series of beautiful hybrids between 

 this and several garden Roses have been raised by the 

 late Lord Penzance, and are known as Penzance Briers. 



R. rugosa (R. ferox). — A very robust shrub, reaching 

 a height of 4 to 6 feet, noteworthy for its handsome 

 foliage. The flowers are rosy-red, followed by bright 

 orange or red fruits. The plant is remarkable for its 

 numerous prickles. There is a white-flowered variety, 

 also one with double flowers. Japan, 1845. Numerous 

 hybrids have lately been raised between this and other 

 Roses. 



R. semper vir ens, Evergreen Rose. — This has long hooked 

 prickles, shining glabrous leaves, and clustered fragrant 

 flowers of medium size. Not so hardy as many of those 

 mentioned. Southern Europe, 1629. 



R. setigera, Prairie Rose. — A climbing species with 

 large, deep-rose-coloured flowers. Useful in flowering 

 late — from July onwards. North America. 



R. spinosissima (R. pimpinellifolia), Scotch Rose. — This 

 is a small -leaved, very prickly little bush-Rose, which 

 grows wild in open places, especially sandy sea-shores, in

the British Islands. It bears a profusion of white or 

 blush flowers for a long season. There are many varieties, 

 of which altaica (R. grandiflora), 6 feet high, with creamy- 

 white flowers, and hispida (R. lutescens), about the same 

 height and with pale-yellow flowers, deserve special 

 mention. 



R. Wichuriana, Monument Rose (fig. 392). — A vigorous 

 trailer suitable for covering banks; the leaves are of a 



glossy dark-green, the flowers white and produced in July 

 and August. Japan, 1892. 



Rosmarinus officinalis. — The Rosemary in deep free 

 soils attains a height of 6 to 8 feet, and should find a 

 place in every shrubbery or mixed flower-garden. It 

 flowers in winter or early spring, and flourishes on the 

 coast. Southern Europe, 1548. 



Rubus, Bramble. — Nearly all the Brambles are of 

 rambling growth and require some support. There are,

however, several of sturdy, erect growth, such as R. delici- 

 osus and odoratus. 



R. biflorus. — Commonly cultivated under the erroneous 

 name of R. leucodermis. It is remarkable for its white 

 stems, which present the appearance of having been white- 

 washed; flowers white, fruit orange-red. It will rapidly 

 cover a large space, and is perfectly hardy. Mountains 

 of Northern India, 1818. 



R. deliciosus (fig. 393). — One of the most beautiful, 

 Its leaves are like those of the Currant, and the stems, 

 which are devoid of prickles, are erect and self-supporting. 

 Its shoots are a yard long, and in May are crowded with 

 pure-white flowers 2 inches across. It is a rather difficult 

 plant to propagate, layering being the most successful 

 method. Rocky Mountains, 1870. 



R.fruticosus. — This is the old name applied collectively 

 to the common Brambles ; they are now divided into 

 numerous species, and some of them are well worth culti- 

 vating. The cut-leaved laciniatus and the double-white 

 and double-pink forms of thyrsoideus and idraifolius are 

 among the best. There is also a variegated variety. 



R. nutkanus. — This and the next have lobed, not 

 digitate leaves. Flowers white, produced from May to 

 October, succeeded by large red fruits. North America, 

 1826. 



R. odoratus. — Similar to the last, but having purplish- 

 red flowers. North America, 1739. 



R. phoenicolasius, Japanese Wineberry. — Although this 

 was introduced from Japan in 1877, it was for some years 

 grown only as a greenhouse plant. It has, however, 

 proved hardy in many districts. Its flowers are pink, and 

 are followed by scarlet edible fruits, like Raspberries, 

 which constitute the chief claim of the plant to recog- 

 nition. The leaves and stems are covered with reddish 

 hairs. 



R. spectabilis. — A desirable North American species 

 introduced in 1827, having trifoliolate leaves, large pur- 

 plish, fragrant flowers and yellow fruit.
