CHAPTER XL 



WILD GARDENING ON WALLS OR RUINS. 



TiiEitE are many hundred species 

 of mountain and rock plants 

 which will thrive much better 

 on an old wall, a ruin, a sunk 

 fence, a sloping bank of 

 stone, Avitli earth behind, 

 than they do in the most 

 carefully prepared border, 

 and therefore their culture 

 may be fittingly considered 

 here, particularly, as once 

 established in such positions 

 they increase and take care 

 of themselves unaided. In- 

 deed, many an alpine plant 

 which may have perished 

 in its place in the garden, 

 would, thrive on any old Avail, near at hand, as, for example, 

 the pretty I'yrenean Erinus, the silvery Saxifrages of the 

 Alps, pinks like the Cheddar Pink, established on the walls 



Arenaria balearica, in a hole in wall at 

 Great Tew.
