the sunnier the spot the better. Soldanellas 

 alpina and minima, dainty little bell-like fringed 

 flowers, require a moist peaty soil and partial 

 shade. The Silenes flourish in any light, loamy 

 soil, as will Scutellaria alpina, Tiarella cordifolia 

 (foam-flower), and the creeping Veronicas. 

 Viola cucullata succeeds best in a moist spot in 

 peat and loam. Wahlenbergia serpyllifolia grows 

 well in sandy loam in a sunny situation.
