If mine freezes, it comes back from the roots. It climbs by tendrils, so you will have to provide a trellis or wire mesh for it to grow on.

Here is a link that might be useful: Coral vine

Would the coral vine be a good candidate to grow up and into a very large tree or could it be harmful to the tree? It appears to be a dainty vine and the tree I'm thinking about is very old and very huge, but unfortunately very unattractive, so I know it could handle any weight the vine has. Thanks
