Chocolate cosmos

[carly]

So I have a chocolate cosmos..... I have a nice big container for it and I know it cannot tolerate low temperatures so will plan on bringing it in from greenhouse over winter. I have been told it should re-flower the following year. How long can I keep this plant going? And any special instructions for its care etc? Tia

Treat it like a dahlia but it's less hardy.

If it survives you can take cuttings in spring like dahlia or divide tuber.
