BLUE GARDENS 
*53 
(blue grass), which would enhance its “ gris 
de Flandres ” colouring. 
Veronica s pic at a ^ Pentstemon glaber (rather 
tender, but lovely), and Catananche ccerulea must 
be noted. Lupinus polyphyllus , centaurea, 
dark blue aconites, Geranium pratense , and 
dark blue tradescantia, if kept together and 
perhaps separated from the other blues by 
some grey-foliaged artemisia, would make a 
dark, purple-toned effect, but must not be 
near any of the cobalt blues, such as Commelina 
ccelestis ; for though the flowers of the latter 
close about 5 p.m., they are most vivid in 
colour. But Commelina ccelestis is a charming 
plant, and blooms till the frost, or the gardener, 
cuts it down. 
If a poor dry corner has to be planted, get 
some of the wild chicory, which loves chalk, 
and whose sky-blue flowers baffle description. 
A never-to-be-forgotten memory is that of 
this lovely wild thing, growing from among 
the tombs of the Capulets in Verona. 
One or two of the Michaelmas daisies are 
very blue, such as Robert Parker and amellus, 
and bloom too late to clash with other things ; 
while the early blue Wilson primroses would 
need to be kept away by themselves, as they 
so often become slaty or even purple in tone.
