Hi there,
I'd like to try this vine, it's really pretty. Everythng I have read says it can be invasive but I don't think this will be so where I live in a dry zone 9b. I have rooted suckers from my mock orange bush (very fragrant) I think you would like, it's a very green tropical looking, but not tropical plant.

Do you still have a start of the variegated porcelain vine?
I have just taken cuttings from a variegated lace cap hydrangea and a green leafed lacecap hydrangea - they are not rooted, but, I could send 2 or 3 of each.
I have a large clerodendrom thomsoniae that I could take cuttings from. They root easily in water.
