I have been given a small one of these in a pot. Looked up how to care for it. It seems to grow very big, needs a trellis, up to 8meters. But needs to be kept frost free and brought inside in the winter. Kept above 10° at night!
How??
I can plant it in a pot, but have nowhere inside it can fgo, especially if it starts climbing up a trellis.
As you can probably tell, I'm not a gardener...
