HERBACEOUS GARDEN 
beautiful in colour that, although a conifer, it 
must be given a place in the grey garden, but 
not where it can be whipped by the leaves of 
other trees and so stunted in growth ; give it 
a centre place in a border or bed rising from 
a carpet of grey foliage, say of cerastium, 
another useful grey, though spreading like a 
weed in a border. 
Last but not least in value comes the most 
beautiful and most distinct plant of recent 
introduction, Perovskia atriplicifolia , a cloud 
of finest, most slender stems of silvery grey, 
some 2 feet high, branching in all directions 
from the .ground, with bluish-purple flowers 
of small size encrusting them. 
To evade sameness in colour it would be 
easy to arrange some good clumps of pink 
gladiolus with the large grey artichoke, and a 
bed of rosemary, lavender, and monthly roses 
would harmonize well with the rest. A few 
tall spires of lemon-coloured hollyhocks, or the 
woolly grey of the yellow- flowered mullein, 
would look well against the soft background. 
Greys need soft tones with them if colours are 
used. Not rich purples, or crimsons, though 
a splash of orange lilies, croceum or tigrinum, 
would not look amiss. Evening primrose is 
happy in a shady corner ; and white bergamot.
