The Garden of British Wild Flowers. 191 



Geum and its interesting varieties, both species 

 very pretty for rockwork and borders. 



Next we have the mountain S. stellaris and 

 S. nivalis, and the yellow marsh S. Hirculus, 

 and the yellow S. aizoides, which fringes the 

 rills and streams on the hills and -mountains in 

 Scotland, and the north of England and Ireland, 

 all interesting and worthy of a trial — but far 

 surpassed by the purple Saxifraga oppositifolia, 

 which opens its vivid purplish-rose flowers soon 

 after the snow melts on its native rocks in the 

 Scotch Highlands, and as far north, among the 

 higher mountains of Europe, Russian and Central 

 Asia, as the Arctic circle. It bears garden culture 

 well, either as a pot plant in the cold frame or pit, 

 on the rockwork, or in patches in the front of a 

 border. In planting this it would be well to exca- 

 vate holes a couple of feet deep, filling them again 

 with a mixture of broken stone and earth, so that 

 when the roots descended among these evaporation* 

 preventing stones, they might find a good substitute 

 for that moisture and that nutriment which they 

 enjoy among the dibris and in the chinks of their 

 native rocks. The purple saxifrage should be 

 planted in- the full sun. 



This caution is the more necessary in conse-.
