90 STUDIES IN GARDENING 



will often recover if moved; and this should be done 

 in spring. There is a pretty white variety, and the 

 type appears to hybridize readily, but no valuable 

 hybrids have been obtained yet. 



Dianthus callizonus is, perhaps, only a local variety 

 of D. alpinus, but it is a distinct and even more beau- 

 tiful plant, with glaucous leaves and brilliant pink 

 speckled flowers. It should be treated like D. alpinus 

 and does not seem to be any more difficult. It is still 

 very rare. Dianthus glacialis is too difficult, perhaps, 

 to be worth growing in England. At any rate, it is 

 scarcely ever seen in English gardens. It needs the 

 same culture as D. alpinus, except that it will not 

 endure lime, and must be even more carefully pro- 

 tected from drought in the summer. The true plant 

 is seldom to be obtained in England; and hybrids or 

 other species are usually sold for it. 



D. Freynii is the smallest of all pinks, with little 

 pink flowers. It should be grown like D. neglectus, 

 and is not more difficult. There is a very beautiful 

 minute mountain pink with large white fringed flowers, 

 which is sometimes sold as D. squarrosus. The true 

 D. squarrosus, however, is a much larger plant, of 

 no particular beauty or interest. The present writer 

 is ignorant of the true name of the white pink in ques- 

 tion, and it is seldom seen in English gardens. It has 

 very minute grassy leaves, and the flowers are borne 

 about 2| in. above them. It requires the same cul- 

 ture as D. neglectus, but is easier to grow. There are 

 many more species of pinks, but many of them are
