Clematis nepulensis

Oooh, lovely!! :)) Me very very jealous!

That's pretty...
is this the first time you've had this in flower ?

No TT this flowers every year, not meant to be hardy but it's survived these last winters, but, but, it's Cornwall. Hate to keep saying it. I do think if given a protected corner & plenty of mulch, fleece, etc. around its bottom you may keep it. Of course it does flower in the winter so you don't realy want to lose its top growth.

Glad to see it is surviving so well for you :o)))
