Cornflowers need Space 
conservatory. Both the type - coloured purple 
and the white should be grown. 
Celosia plumosa ( The Feathered, not the 
Crested Cockscomb) ; g.a. — Celosia is most com- 
monly represented in gardens by the magenta 
Cockscomb of greenhouses, a plant unbeautiful 
both of form and colour. The feathered kinds, 
in which the flower has the form of an upright 
plume, when the harsh crimson colouring to 
which they naturally incline can be avoided, 
are handsome plants both for garden and green- 
house, in colourings of red and yellow. As they 
begin to show bloom in quite a small state the 
bad ones can be picked out. But they need 
careful growing. Sow towards the end of 
March, keep close to the light, and as they in- 
crease in size give successive shifts. Push on 
in heat, and harden off carefully before putting 
out. As rapid growth is required, they should 
be repotted in rich soil. 
Centaurea cyanus ( Cornflower ) ; h.a. ; 2 to 
3 feet. — A native plant of improved form, pure 
blue, about 3 feet high. Best autumn sown 
outdoors, when, if given space, a single plant will 
branch a yard wide. The dwarfer forms are 
not so good as the tall. There are purple and 
white varieties, but the strong, pure blue and a 
rather lighter blue are the best.

C. Margarita {White), and C. suaveolens
