This question probably only applies if you are in London or Cornwall
as I understand it is not totally hardy....

many thanks if you can help

Dave Poole kindly sent me some seed, and I have got one plant to
survive and flower. It was about 9" high, weedy, and may not come
through the winter. It bears the same sort of relationship to
invasive plants as Ethelred the Unredy did to the Vikings.

However, the books and he refer to it as growing several feet high,
so it may not be representative!
