136 ROCK GARDENING FOR AMATEURS 



the summer and autumn. Increased by seeds, division, 

 or cuttings. 



D. fragmns (Fragrant Pink). An easy rockery Pink 

 from the Caucasus, needing sandy loam and grit. It 

 forms a compact plant, and produces pretty, white, 

 fringed, and fragrant flowers freely. It likes sun and a 

 light soil. Increased by seeds or cuttings. 



D. graniticus (Granite Pink). A glorified form of the 

 Maiden Pink, though rather taller, and with bigger flowers 

 of rose colour, with a darker zone. It blooms from June 

 onwards. It thrives in a sunny place and gritty soil, and 

 is easily propagated from seeds, by division or cuttings. 



D. hybridus (Mule Pink). This name covers the many 

 forms of Mule Pinks, which are exceedingly varied. Some 

 think them too artificial-looking for the rockery, as a 

 number of them have double flowers. Most Mule Pinks 

 are bright, however, and some live a long time without 

 much attention. Others, again, require to be propagated 

 from cuttings almost every summer. The most brilliant 

 is Napoleon III., with glowing crimson flowers ; it often 

 fails to produce growths suitable for cuttings. As soon 

 as it has done flowering the flower stem should be cut 

 down to encourage fresh shoots. It is advisable to obtain 

 two plants of most of the Mule Pinks : one of them 

 should not be allowed to flower, so that it may yield 

 cuttings. Atkinsoni is good ; Salmon, excellent, and 

 Fiirst Bismarck, Fettes Mount, Marie Pare, Emilie Pare, 

 and others will well repay cultivation. They should 

 have sun and a gritty soil. Increased by cuttings.
