More Details

Cosmos sulphureus is a great colour mix of deep-orange and tangerine flowers in single and double forms. Its stems need searing in boiling water to make the flowers last.

Cosmos flower 14 weeks from sowing, last 10 days in the vase, produce at least two buckets of cut flowers a week from a 1x 1m patch and do so from late June until November – so that'snearly fifty buckets of flowers in one season from a small patch. They are impossible to beat.

Reviewed 19th September 2018 by Caroline Carroll

I don't have a greenhouse so grew these on a windowsill and about ten survived. they were planted quite late and so didn't start flowering until late August, but what a great plant to have now when others have finished. They are a big bush rather than single stalks like other cosmos and just go on and on with regular deadheading. I'd recommend,.
