Gardeners' Notes:

Positive LeslieT On Mar 15, 2010, LeslieT from Bellaire, TX wrote:

I've tried a number of passion vines, native and different cultivars; this is the ONLY one that hasn't seeded everywhere in my Houston-area garden. Some fancy cultivars rarely bloomed. P. Allardii bloomed almost constantly in my garden. For over five years I enjoyed it in two places with not a single seedling popping up. This cold winter appears to have killed it; there's no sign it's coming back from its roots although I would love it if it would. I'd originally purchased it from Kartuz Greenhouse which is sold out of them.

Negative because I don't want it. It was here when we bought the house. It just won't die. We've cut it down, put plastic over it, we don't even water it and it always finds a way. The flowers are pretty - looks like an alien flower. It's viney and in Virginia beach, in my back yard, it just keeps going on.
