Since it is a C. persicum type I would not expect it to survive outdoors anywhere where it got more than a light touch of frost. Certainly they do not survive outdoors here where we get -2 or -3 c., on a regular basis throughout Winter and often even much much lower.

Thank you Owdboggy. It is as I expected....I will stick with the tried and tested hardy forms and forgo the bright scarlet flowers. Christrpc

However if you plant them in a small trough and can bring them into a front porch or similar when it is frosty they do very well. I buy a pack of six from our local nursery and sometimes even manage to get them through two winters...

Thank you moon growe. we have a conservatory but I have difficulty in keeping the tender ones doing really well after their initial year. They are lovely though. Christrpc
