Cosmos for the Autumn 
May. Good for trellis or for covering any rough 
support. 
Convolvulus minor, properly C. tricolor. 
— A lovely plant about i foot high ; flowers 
blue, shading to a white throat, the blue 
accentuated by yellow stripes passing up from 
the centre. 
Coreopsis tinctoria. — One of the brightest 
of the taller hardy annuals, about 3 feet high, 
with a profusion of Daisy-shaped bloom of a deep 
orange colour with rich mahogany-brown centre. 
A variety called atrosanguineum is of the maho- 
gany colour all over. C. Drummondi, rather 
shorter growing, is a rich yellow. There are 
dwarf varieties of C. tinctoria ; the one named 
Crimson King is less than a foot high and has 
rich red-brown colouring. Sow April to June 
or in September for early blooming. 
Cornflower. See Centaurea. 
Cosmos bipinnatus ; h.h.a. ; 6 feet. — Flowers 
in September and October. The type colour is a 
washy purplish-pink, but there is a good white 
variety which is preferable. A good companion 
to the late Michaelmas Daisies. There is a 
useful dwarf kind, flowering from J uly onwards ; 
of this the white is also the best. When the 
plants are half grown they may be made more 
bushy by being cut back, when they make fresh 
side growth immediately.
