176 ALPINE FLOWERS AND ROCK GARDENS. 



rose, are generally grown in preference to it. All form 

 cushions of dense green foliage. 



Trifurcata has somewhat larger flower stems than 

 the preceding, and may therefore be used for cutting. 

 The flowers are white, produced in the spring. Cerato- 

 phyllUy the stagshorn Rockfoil, so called owing to the 

 form of the foliage, is a popular form of trifurcata. 



Wallacei (Camposii). — ^This has much larger flowers 

 than the other short-stemmed Mossy Saxifrages, 

 and is much in request. It is white, and blooms in 

 spring. It is a splendid sort. 



The following are some of the best in the encrusted 

 section. They produce pretty silvery rosettes, and 

 long, slender panicles of bloom. They do not, of course, 

 spread as fast as the mossy section, still, they grow 

 quite freely in a dry sunny position. They are at their 

 best in gritty loam between stones. 



Aizoon. — Cream flowers spotted with red produced 

 in panicles six to ten inches long in June. There 

 are many varieties, amongst the best being Carinthiaca, 

 white ; La Graviana, white flowers on red stems ; 

 Malyi^ white ; and Sturmiana, cream, dwarf habit. 



Cotyledon. — Produces beautiful white sprays in 

 May. The variety pyramidalis bears lovely plumes, 

 and is much better than the species. Both are about 

 eighteen inches high. 



Hostii. — White flowers on reddish stems nine to 

 twelve inches high, produced in May. 



Lingulata. — Long sprays of white flowers in May, 

 produced very freely from silvery rosettes. Lantoscana 

 (see photograph) and superba are good forms of it.
