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,.
