DESCRIPTIVE LIST OF THE BEST KINDS 251 



Erythroniums have flowered in the early summer, and 

 have died down, leaving the ground bare. Another 

 member of the family is the Cloudberry (R. Chamaemorus), 

 with large white flowers on leafy stems in summer, five 

 to seven lobed leaves, and orange-yellow fruits. It is 

 a common plant on the moors of northern England, but 

 is somewhat difficult to establish in the south. R. pedatus 

 creeps about like a Strawberry, and also has white flowers, 

 succeeded by bright red fruits. It comes from North 

 America and grows very freely. R. Xanthocarpus, a 

 Chinese species, is of a dwarf sub-shrubby habit, spreading 

 about by means of underground stems. It also has white 

 flowers followed by yellow fruits. 



Saponaria (Soap wort). Several of the Saponarias 

 which belong to the Pink family (Caryophyllaceae), 

 and are native chiefly of Southern Europe, are showy 

 rock-garden flowers. Well-drained sandy loam suits 

 them well, and they like a sunny position. They should 

 be placed high up in the rock garden, so that their 

 trailing stems may have plenty of rock face or bank 

 over which to fall. Perfect drainage, so essential to 

 their welfare, is thus also secured. Saponaria ocymoides, 

 found wild on the Swiss Alps, bears rose-pink flowers 

 very freely in May and June. There are several varieties, 

 alba, splendens, and others. S. caespitosa, from the 

 Pyrenees, is a dainty little tufted plant yielding rose- 

 coloured blooms in July ; but it is less hardy than 

 S. ocymoides. S. Boissieri, of garden origin, is said to 

 be a hybrid between S. ocymoides and S. caespitosa.
