120 THE NEW GARDENING 



each should be set in a small colony among the stones, 

 where they will make bright and sparkling masses of 

 bloom. 



One of the most exquisitely beautiful of the Saxifrages 

 is Boydi, a hybrid raised from the Swiss species aretioides, 

 which has yellow flowers ; and Burseriana, a species 

 with cream flowers from Carniola. Boydi bears its leaves 

 in rosettes, and is covered in spring with a multitude of 

 bright yellow flowers on stems about four inches high. 

 It is a most precious little plant, which the Alpine lover 

 will do well to find a place for. A white form, called 

 Boydi alba, is available, and is pretty, but, there is a good 

 number of white Rockfoils. Boydi crossed back with 

 one of its parents, Burseriana, has given the sub-hybrid 

 Faldonside, which has large cream flowers. The Boydi 

 set bloom in the spring, and form a choice little assort- 

 ment of dainty Saxifrages. Among the other special 

 forms of Rockfoil may be mentioned oppositifolia W. A. 

 Clark, a reddish mauve variety of very deep rich colour. 

 The species itself is British, and has purple flowers in 

 spring ; but it is generally represented in gardens by the 

 larger variety major. Macnabiana crossed with lantos- 

 cana superba has given the beautiful hybrid Dr. Ramsay, 

 an encrusted form which produces a large spray of white 

 flowers dotted with rose in spring. Of the parents, 

 lantoscana is a species from the maritime Alps, with 

 creamy flowers ; but to keep in line with modern botanists 

 it should be described as a form of lingulata. Macnabiana 

 is probably a hybrid. Moschata is a little -known 

 Pyrenean species, and Stormont's variety, with pink 

 flowers on stems about four inches high, may represent 

 it in gardens. These modern Saxifrages love the free air, 

 and to get the vivid and sparkling colours at their richest 

 it is necessary to plant them out and give no protection
