Cosmea (half hardy annual) COSMOS

Cosmea is a popular annual which is easily recognised by its slender shape, delicate ferny foliage and large flowers which look like single Dahlias. Grow it in pots or flower beds for cutting or for a summer-long display outdoors. Stake tall varieties and remove dead blooms to prolong the flowering season.

VARIETIES: Most garden Cosmeas are varieties of C. bipin-natus. The usual choice is ‘Sensation Mixed’ – 3 ft tall with white, pink or red flowers. The red-and-white patterned ‘Candy Stripe’ is more eye-catching. The varieties of C. sulphureus have bright flowers and wider leaves. Choose from ‘Sunset’ (3 ft. orange, semi-double), ‘Klondyke’ (2 ft. orange, double) or the new dwarf ‘Sunny Gold’ (1 ft. orange, double).

SITE AND SOIL: Any well-drained garden soil, but light or medium land is preferred. Choose a sunny spot.

PLANT DETAILS: Height 1-3 ft.

Spacing: 1.5 ft.

Flowering period: July-October.

PROPAGATION: Follow the Half Hardy Annual technique . In mild districts sow seeds outdoors in May.


Flowering period: for nearly all annuals and biennials lies somewhere between the beginning of June and the end of October. However, by careful selection you can have flowers in theannual bed or borderalmost all year round. For each month there is a list of annuals and biennials which can be expected to be in full bloom – remember that some of these plants may come into flower earlier and can continue to bloom for many weeks afterwards.
