GOOD TREES AND SHRUBS 241 



they take longer to reach planting size than grafted ones, but there is no 

 trouble in looking after suckers, as is the case with grafted plants. Cut- 

 tings of the young ripened wood emit roots plunged in a warm close 

 case in sandy soil. Layering is another means of increasing the stock. 

 Select nice well-ripened shoots, and peg them into the soil, which should 

 be kept moist. Grafting is resorted to principally in the case of 

 hybrids. 



Attention is first directed to a few of the best of the deciduous 

 kinds : 7?. arborescens, an American species, flowers rather later than 

 most of its congeners. Its reddish sweet-scented flowers are borne 

 freely. R. viscosum (Clammy Honeysuckle) merits attention on account 

 of the freedom with which its white-scented flowers are borne. R. 

 occidentale, the Western Azalea, produces a wealth of white sweet- 

 scented flowers, the base of the upper segments being blotched with 

 yellow. It flowers late in the season, and its autumn-tinted foliage is 

 very bright. R. Seklippenbachii, an uncommon species from China, has 

 large delicate pink flowers spotted with crimson. It is quite hardy, of 

 excellent growth, and grand for massing. R. calendulacea grows about 

 six feet high when suitably placed. It flowers freely, and is orange-red 

 in colour. R. rhombicum, from Japan, is a valuable shrub, and quite 

 hardy. Its rosy-purple flowers appear early, and are welcome because 

 few other shrubs are in flower at the same time. R. Vaseyi is another 

 free-flowering kind from America. Its delicate white and pink flowers 

 are carried in loose clusters. R. dauricum belongs to the very early- 

 flowering section. It is of rather straggling habit, three feet high, 

 and bears purplish-coloured flowers in abundance. R. flavum, better 

 known as R. pontica^ is a showy plant in spring. Its large flowers are 

 borne in clusters, and the colour is yellow or orange, and R. sinensis is 

 another attractive kind. The gorgeous coloured hardy hybrids and 

 varieties have originated principally through the crossing and inter- 

 crossing of such species as R. calendulacea, nudiflorum, occidentalis, 

 viscosum, jlavum, sinensis, &c., the progeny, of course, being worked 

 again in the same way. 



Species with evergreen leaves : R. Fortunei is a precious Chinese 

 shrub with large sweet-scented flowers in great clusters, ground colour 

 white, with a delicate suspicion of pink throughout. It is hardy and 

 very uncommon. R. Smirnowi is another uncommon species, perfectly 

 hardy and very showy. It forms a sturdy bush, and carries lilac- 

 coloured flowers with wavy margins in compact trusses. R. niveum, a 

 Himalayan species, deserves a sheltered place in the garden for its bold 

 leaves, which in shape resemble those of a laurel, the under sides being 

 covered with a white woolly substance. The flowers are soft lilac, 

 blotched with rosy-lilac. R. Thomsoni and R. campanulatum, also 

 Himalayan species, grow freely and flower well in the neighbourhood of 

 London. Both make an even growth, the first named bearing clusters 

 of rich crimson flowers, and R. campanulatum neat trusses of lilac- 

 coloured blossoms spotted with purple on the upper segments. R. 

 glaucum is dwarf and very beautiful, flowers light purple. R. campylo- 

 carpum is a dainty dwarf species with delicate yellow flowers.
