94 PRESENT-DAY GARDENING 



Dianthus alpinus. This species belongs to the low- 

 growing type, and it is one of the prettiest of them. The 

 flowers are large for the size of the plant ; they are rose- 

 coloured, with blotches or spots of deep red. The petals 

 are notched, as are those of most of the species. 



D. arbusculus (Shrubby Chinese Pink). I have not 

 seen this in flower, but it is described in Nicholson's 

 Dictionary of Gardening, and it is figured in the Botanical 

 Register, Plate 1086. It is stated to be half-hardy only, 

 and was introduced from China for the Royal Horticultural 

 Society, in 1824, by D. Perks. It is said to flower freely 

 from July to October. The flowers are semi-double and 

 large, of a delicate, rich-purplish colour ; they are produced 

 in terminal panicles. 



D. arenarius (the Sand Pink). This species is figured 

 in the Botanical Magazine, Tab. 2038, and seems to have 

 been in cultivation for a long time. It has been described 

 as having purple flowers, but the variety illustrated in the 

 Bot. Mag. is white, with a faint greenish spot in the 

 centre, and covered with short, dark-purple hairs. The 

 petals are deeply divided into narrow lobes. 



D. carthusianorum (Carthusian Pink). This is a very 

 distinct and pretty species. It grows freely on any chalky 

 soil. The flowers are collected into a close head, twelve 

 or more together, on stems a foot to eighteen inches high. 

 It does not grow in all gardens so freely as some species. 

 It is figured in the Bot. Mag., Tab. 2039. Except in the 

 pink colour of the flowers, it does not differ materially from 

 D. atrorubens, or D. capitatus. 



D. carneus. This species forms a neat plant, and 

 flowers in any rock garden on the chalk in summer.
