A friend of my Dad's gave me a cutting of this scrambling vine from his garden in Cornwall. He had no idea what it is and nor do I. It hasn't flowered so I think it's foilage only & it is somewhat tender. The good news is... it grows like a weed - since spring it grew from 2 inches to about 5ft. Cuttings take really easily - no skill at all required! So If current batch of cuttings survive the winter, will have some to share next year. Grateful for any possible names or pointers in the right direction. Cheers all.
