VIIL — A Selection of Ferns. 



The use of ferns might strike the beginner as fanciful, 

 inasmuch as it is a recognised point about the rock- 

 work that it must be in sun, and of ferns that they must 

 be in shade. Given a small, made rockery, occupying 

 only a square rod of ground or thereabouts, fully 

 exposed to sun, ferns may be left out of consideration ; 

 but in those cases where the culture of Alpines extends 

 to a real garden there will be spots at the side of 

 paths approaching the rockery, on shady banks, in 

 dells or under trees, where ferns would grow, and 

 where their cool and shady verdure would be a great 

 charm. 



It is a fact that most ferns love shade and moisture, 

 and the exceptions are few. But those who see them 

 growing in the stony banks and on the roofs of caves 

 in Devonshire and Cornwall know that so long as they 

 receive abundance of humidity they do not need the 

 bed of peat which is supposed to be another of the 

 essentials of their culture. I find many thrive in a few 

 inches of poor soil on a chalk bank where they have 

 only shade to help them.
