Getting back to the question of a hardy future, I have a variegated magellanica which has survived outside for 5 or 6 years despite winters down to -25C. It's in a well drained spot in fertile soil and gets full sun in spring and then is shaded in summer.
It can be late getting going again after a very hard winter but it does survive and I dare say if I gave it more TLC would recover faster.
Reading this has given me enthusiasm. I think I will give it a go.I think that all the fuchsias I have have already been pinched out so I will have to start by taking a cutting and hope it roots.
Why has fuchsia become future in my post? Mystery.
I have some more tender fuschias a friend gave me and I've overwintered those under a skylight in an attic that doesn't get below -5C and they're looking very sad. i think we'll have to have a chat about being positive.
Good hardy Varieties: Army Nurse, Celia Smedley, Chillerton Beauty, Dollar Princess, Falklands, Phyllis and Snowcap to name a few. These are the ones I would not be without.
Very easy to do Bunny - I make them all the time for people - will post a photo of mine when it's up and running.
There is a photo of mine somewhere on this site from last year.
