170 ALPINE FLOWERS AND ROCK GARDENS 



association with Gentiana brachyphylla, and in another 

 with G. acaulis. It is a native of Britain, and has deep 

 lilac flowers with a yellow eye, borne on a stem six 

 inches to a foot high in summer. There is a larger 

 form called Wareiy and a white variety called alba. 

 Scotica, which bears purple, yellow-eyed flowers in early 

 summer, is another variety. It is the Scotch Bird's 

 Eye. These like moist, cool soil. If grown on a dry 

 rockery mix leaf mould and chips of sandstone with the 

 soil. There is a stemless form of farinosa called 

 acaulis. 



Forresti is a modern Chinese species that is likely to 

 become very popular. The strong stems rise twelve 

 to fifteen inches high, and bear deep yellow or orange 

 flowers, very sweet. 



Floribunda and its varieties hardly come within our 

 range, although they are beautiful, as they are green- 

 house plants. The same remarks apply to Kewensis, 

 which is a hybrid between floribunda and verticillata. 



Integrifolia is a gem for the rockery, as it forms 

 dense low tufts, and bears its purplish rose flowers in 

 great abundance in late spring. It is a native of the 

 European Alps. It is the subject of one of the coloured 

 plates and appears in another with Ranunculus alpestris. 

 This Primrose is sometimes grown under the name of 

 Candolleana. It is an easy plant to grow, thriving in 

 sandy loam, with hme. 



Alpina (rhetica) is a May bloomer, with purple 

 flowers, growing six to eight inches high. It is shown 

 in one of the coloured plates in association with 

 viscosa.
