30 Alpine Plants. 
soil. This plant sometimes comes up some inches 
from its original site. After flowering, top-dress right 
up to the collar of the plant with gritty loam, 
and in autumn top-dress with fine limestone. In 
spring this plant should be examined, as its collar 
is apt to become barred during winter. If, in the 
course of growth, the collar of the plant becomes 
pushed too far forward, it should be supported by 
a stone packed in with a little loam. 
Campanula pulla (E. Europe), 
Does well treated like Campanula pulloides, of 
which it is one parent. 
Campanula X pulloides (Gar. Hyb.). 
Treat like Campanula rupestris, except that a 
little limestone added along with the gritstone is 
beneficial, and that the top-dressing required should 
consist of fine leaf-mould and fine grit clear of dust. 
Campanula rupestris (Hab. °). 
Plant this rare species between stones in a 
sloping crevice, or on a bank over which it can hang, 
in a well-drained, sunny position, facing full south, in 
equal parts of loam and sand, or of loam, grit, and 
leaf-mould. In spring, and again in autumn, top- 
dress with a little fine grit freed from dust worked 
well among the shoots, as the foliage is very woolly. 
If the autumn top-dressing is made with fine carboni- 
ferous limestone, the foliage will be more farinose in 
the following spring. 
Campanula Tommasiniana (Istria). 
Treat like Campanula Waldsteiniana.
