This new and beautiful annual makes equally as fine a show on the borders 
as the C. bicolor. Where it was raised, or, if introduced, by whom and when 
we cannot tell. Mr. Thomas Bailey furnished us with the figure from his Grace 
the Duke of Devonshire's garden, at Chiswick, and he states that he received it 
from Mr. Knight, King's Road, under the name of Calliopsis sanguinea. 
The 'flowers are liable to vary, some being entirely of that fine deep blood 
colour, which composes the centre of the old C. bicolor (Coreopsis tinctoria), and 
others have a very narrow margin of rich yellow. 
It is perfectly hardy, and, like the C. bicolor, requires the most simple culture, 
the seeds merely requiring to be sown in the open border, and the plants kept free 
from weeds. Common light loam suits it very well. 
The generic name is derived from the Greek word kallistos, most beautiful, 
and opsis, eye, or most beautiful to the eye, alluding to the splendid show made by 
the flowers when expanded. The specific bicolor is given from the two very 
distinct colours of the flowers.
