NEW AND BEAUTIFUL ROCK" PLANTS 161 



former has cream and the latter pink flowers ; both are 

 scented. There is a variety of Cneorum called major 

 which has larger, deeper-coloured flowers than the type, 

 and is desirable. They like peaty soil, and are the better 

 for being pressed well down to the soil. Propagation is 

 by layers in autumn. These charming plants are ever- 

 greens. 



DIANTHUS (ALPINE PINK). There are several plants 

 in this lovely genus besides the familiar Alpinus, deltoides, 

 neglectus, caesius and superbus, which are worthy of 

 the attention of flower-lovers. I may instance Atkinsoni, 

 a beautiful plant, blooming in May, with bright crimson 

 flowers. It differs from deltoides, which will thrive 

 on an arid wall, in requiring a shady position ; it is, 

 however, hardy. It is a difficult plant to propagate, 

 as it makes very little growth, and to get shoots for 

 cuttings flowers must be removed in order to encourage 

 growth. Snowdrift, double white, is a beautiful Pink, 

 probably a form of plumarius. Graniticus is not much 

 grown ; it resembles deltoides, and is perhaps a form of it, 

 but is a larger flower. The variety of caesius called 

 grandiflorus will interest those who admire that species, 

 and the white variety of Alpinus is noteworthy. 



EDRAIANTHUS SERPYLLIFOLIUS. A synonym of 

 Campanula serpyllifolia, a plant of prostrate habit, with 

 purple, bell-shaped flowers on wiry stems, borne in early 

 summer. There is a fine form called major. 



EPIMEDIUMS. Beautiful plants, which are rapidly 

 rising in favour for the rock garden. They form compact 

 masses of graceful foliage, above which the flowers are 

 borne in pretty panicles. A point in their favour is 

 that they will thrive in shady places. Alpinus, with
