 the rocky heights. 



There is also a class of shrub of trailing character 

 that is most useful for leading from those of stiffer 

 growth on the higher ground, to the lower regions 

 where there will be more flowery plants. The low 

 growing Cotoneasters, Savin, and Muhlenbeckia, are 

 some of the best of these, and Heaths of many kinds 

 from the tall Tree Heath of the Mediterranean to 

 the low-growing and early-blooming Erica carnea.

 well exceed the usefulness of the white Menziesia, 

 for it is not only a neat dark green tuft in winter, 

 but in all the summer months and even into autumn 

 it bears its large Heath-bells in good quantity. 



These dwarf shrubs should be planted so as to

 above, following and accentuating the stratified lines 

 in which the stones are laid. If they are planted just 

 above the stones they will fall naturally into their 

 places. 



It will also add greatly to the feeling of general
