The thing that's so frustrating is that it used to be widely available. Then I heard that cold weather in Fl wiped out most of it. Glass House Works had it in their catalog, so I ordered one (a year ago), only to be told they had 'lost' the plant...so close, and yet so far away!
Many of the growers I've contacted have never heard of it. I planted it outside as groundcover in SoCal but it died out due to the cold- (it's from SE Asia), but I haven't seen it in over 30 years. I've got a 'snow in summer' asiatic jasmine, with white and pink variation. But now this plant has become an obsession
