166 HARDY SHRUBS. 



on seedling stocks. The flowers of P. Mains coronaria are large, single, 

 pinkish-white, very sweetly scented. It bears fruit freely, bat the seed- 

 lings are slow in making flowering plants. P. M. floribunda and the 

 variety called atrosanguinea are most beautiful when the flowers are 

 half expanded ; they are then of a bright rosy-red color, getting lighter 

 when fully open. The flowers of P. M. Parkmanni are double, of a 

 beautiful deep rose; valuable for cutting. It is a very free flowering 

 variety and should be largely grown. P. M. carnea and P. M. lutea 

 produce large numbers of flowers on small grafted plants. The double 

 white and double rose colored forms of P. M. spectabilis are very desira- 

 ble; they are very regular bloomers, seldom missing a season. P. M. 

 floribunda and P. M f. atrosanguinea bloom freely in a small state, and 

 should be grown more for forcing purposes. 



RHAPHIOLEPIS OVATA— A charming little evergreen shrub, which is 

 hardj^ here in sheltered situations. The flowers resemble those of a Cra- 

 taegus; they are pure white, sweet-scented, about three-quarters of an 

 Inch across and arranged in terminal panicles. The leaves are leathery 

 in texture and almost round. It ought to prove a good shrub for the 

 Southern States. It is easily propagated by cuttings in the Fall, rooted 

 indoors. 



RHODODENDRON.— In some parts these do grandly. In this locality, 

 when given sheltered and partly shaded positions, they thrive tolerably 

 well, but when in the full sun they do not thrive unless very carefully 

 watched. Hybrids of R. ponticum are less hardy than those of R. 

 catawbiense. This species and R. maximum are natives of the Eastern 

 States; they should be given treatment similar to that recomended for 

 Azalea. They are propagated by layering and grafting on seedling 

 stocks of the hardy species, principally R. maximum. R. punctatum,a 

 species from N. Carolina with small pink flowers, is quite hardy North. 

 There are many beautiful greenhouse species and varieties, compara- 

 tively few of which are cultivated in America. 



RHODOTYPOS KERRIOIDES (White Kerria)— This is a very desirable 

 Japanese shrub, seldom growing over 8 feet high, although in its native 

 country it is said to reach twice that height. The flowers make their 

 appearance as soon as the growths of the current year develop, and 

 keep up quite a display from about the middle of May all through the 

 Summer and Fall months; that is, if the ground does not get too dry. 

 The flowers are snow-white, aobut 2 inches in diameter, and appear at the 

 ends of the shoots. The plant thrives well on heavy soils, and, although 

 not necessarily, in places crowded and partly shaded by overhead foli- 

 age. The seeds are in shape and size somewhat like those of the Canna. 

 They may be sown as soon as gathered, as they are slow in germinating. 



RHUS COTINUS (Smoke Tree)'-A species from Southern Europe, with 

 very neat foliage. The whole plant is usually covered during mid- 

 Bummer with a fringe-like substance, which gives rise to the name 

 " Smoke Tree." This substance consists of the elongated hairy pedicels. 

 R. glabra is one of the handsomest species, on account of its large, odd- 

 pinnate leaves. R. g. laciniata has the leaflets much cut up, resembling 

 the fronds of some Ferns; both are easily propagated from cuttings of
