HERBACEOUS GARDEN 
a foot apart you will get a large mass of well- 
grown branching stuff, instead of one small 
and crowded clump, which would have been 
the case if you had left them undivided as 
they came from the nursery gardens. 
Last autumn I bought two plants of that 
grand new aster Climax, and by dividing into 
little pieces when it arrived, and again in the 
spring, I had three splendid groups of it this 
autumn, groups consisting of three or four 
plants ; and I have even been able to give 
away a clump. 
Asters and phlox are particularly suitable 
for division in this way ; and indeed it is 
imperative to grow them in small pieces, 
planted out annually, to get the best results. 
Delphiniums are best divided in early spring, 
unless on a very warm, sandy soil. 
A plant of anchusa can be increased by 
cutting up the roots into pieces of 2 and 3 
inches long in early spring, and replanting in 
boxes in cold frame, and will give you any 
number of plants. But if left to itself, it will 
die out in a year or two. 
A plant like Santolina incana , grown for its 
grey foliage, only needs pulling apart with the 
fingers, and each twig will grow if firmly
