This genus includes several valuable garden plants, notably the Carnations, Cloves, and Pinks (D. Caryophyllus), the Sweet William (D.barbatus), and a, large num-her of valuable alpine species suitable for the rock garden. One of the best-known kinds is D. chinensis (fig. 193), the Indian or Chinese Pink. It is a biennial, 6-12 in. high, with red flowers. There are, however, many forms of it, both single and double, of which the follow ing are the best: albus, white; carneus, flesh pink; fulgens, scarlet crimson; Crimson Belle, deep red; Eastern Queen, deep rose; laciniatus, with jagged petals and single and double forms; Heddeweggi, a fine variety, with tingle and double forms of various colours; im-perialis, a taller variety, with double Mowers that are useful for cutting. A trade is done in the seeds and young plants in spring, the cultural treatment of the latter being the same as for half-hardy annuals like the China Aster, Zinnia, etc.
Amongst the kinds suitable for rock and alpine gardening, and in which a trade is largely done in pot plants, the following dwarf tufted ones are grown in larger or smaller quantities by specialists: acaulis, bright pink; alpestris, bright rose; alpinus, deep rose; arennarius, white with crimson spot at the base; Cassius, rose, the "Cheddar Pink"; callizonus, rich rose purple; carthusianorum, bright rose; deltoides, bright red, the "Maiden pink", of which there is a white variety; dentosus, violet rose; fragrans, white, tinged purple, with a double variety having creamy white flowers; Freyni, rose lilac, very dwarf and tufted; frigidus, pale purple; glacialis, purple; Holtzeri, pink; integer, pure white; Knappi, clear yellow; mon-spessulanus, red or white; neglectus, carmine (fig. 194); petroeus, rose, with a very double form; ramosissimus, purple rose; Seguieri, rose purple; Simsi, pink; sub-acaulis, pink; superbus, pink and white; sylvestris, rose pink; and zonatus, bright rose, dark centre. Most of the above form dwarf tufted masses, and are chiefly appreciated by the owners of large gardens where there is scope for the establishment of rock and alpine gardens.
