I bought this last month and planted it in the garden. Should I pot it up and keep it over winter in the cold greenhouse. It was said to be a perenial and hardy but I have also read that these are more often grown as annuals. I would like to keep it if possible.

Thank you Verdun. I will do that and keep my fingers crossed.....
Oh, thanks for posting this. I bought one a few weeks ago, didn't realise it was more of an annual. Planted it outside and was planning on leaving it there. Anyone else grown one.

I live in west central Scotland - not where that photo is...
