I now
have (another) one! Got it free from the local Council. So pleased it appears to have settled in and is growing. I want it to cover this hole in the fence-covering foliage. This is a purple one.
They are also called 'Happy Wanderer', 'False Sarsparilla', 'Coral Vine', and 'Purple Vine Lilac'.
I have sent away to ebay for the pink and the white varieties.
Some pics to anticipate!
