Plant Description

Coreopsis grandiflora

Double-flowered Coreopsis, possibly Coreopsis grandiflora Sunray in the garden of Robin Diehm in Sydney

Sometimes known as tickseed, Coreopsis is a member of the Asteraceae family of plants, found in prairies and woodland in North and Central America as well as in Mexico. They have brilliant yellow-gold daisy-like flowers, which can be cut for vases. In Sydney, the common form, Coreopsis grandiflora, is actually a weed and can be seen growing wild along railway lines, as it spreads readily by seed. However, I grow an unusual double Coreopsis (ht 50 cm) which has fluffy blooms in the same dazzling golden-yellow hue. It is possibly Coreopsis grandiflora 'Sunray', and this one does not spread by seed. It quickly forms a perennial clump and blooms from spring until autumn, perfect for hot-coloured flower borders. It is best in a sunny, well-drained position. It tolerates drought well, and is also thriving in our farm garden despite very dry conditions. Occasional deadheading will help prolong the flowering period. Regular division of clumps is recommended. It makes a good cut flower.

Postscript: I don't grow this at the moment, but hope to find it again one day.
