32 WALL AND WATER GARDENS 



In an important position in the cool wall will be 

 a good planting of Ramondia pyrenaica. This ex- 

 cellent plant cannot be too highly estimated. Its 

 home in nature is in cool clefts in mountain gorges, 

 where it constantly receives the mountain mists or 

 the spray of the torrent. It is best in the lower part 

 of the wall, but if the wall is of fair height and 

 backed by a cool mass of earth, it is well to have 

 it on the eye level. Near it should be a plant of 

 the same family, Haberlea rhodopensis, smooth-leaved, 

 and with much the same habit of growth and yet of 

 quite different appearance. 



The wall will give an opportunity for succeeding 

 with many Alpine Primulas, some of them difficult 

 in ordinary rock cultivation. Alpine Auriculas and 

 any garden Primroses will be charming in some of 

 the lower joints, and the lovely P. Monroi, or more 

 properly P. involucrata, one of the most dainty of its 

 family, will here do well. Others worth growing in 

 the wall will be P. Allionii, P. ghitinosa, P. marginata^ 

 P. nivalis, and P. viscosa. 



The beautiful Androsaces, good alike in sun and 

 shade, will have their place in the wall. The Hima- 

 layan A. lanuginosa seems to be one of the most 

 willing to grow in English gardens, where its silky 

 rosettes of foliage and pretty heads of pink flowers 

 will fall over the face of the rocks, clothing them in 

 a charming manner (see p. 94). A. Laggeri of the 

 Pyrenees and A. carnea and A. chamcBJasme of the Swiss 

 and Austrian Alps should also have a place. 



Anemone apennina should be planted in the lower
