OK, so now that's done well in the heat of San Diego...uh, wait, San Diego isn't actually too hot though is it? Does anyone know of one of this type of passion vine that might be heat tolerant? I mean really heat tolerant?
AZ, with your heat, Susan Brigham or Coral Glow would be your best bets of the long tubed type. I had the Coral Glow when I lived in Escondido. We often had temps over 100 and it did well for me but it must be in the ground to do so.
