I think that's right, Ursula. This if the 3rd season for this plant. It climbed 20ft. up into the bamboo last spring, and put out one flower 'way up there. I carefully pulled it down and wrapped it onto a support, and got one more flower last year. This year it has lots of buds.
That's right, Jim. This one I have is on the south side of my big stand of bamboo, so it stays very warm and is protected. Down side is in summer, the bamboo shades it when the sun is high, so it reaches up and climbs into the bamboo. If I ever get fruit, you can bet it will be up there 30ft. off the ground. Oh well, I usually wait until the passion fruits drop to harvest them anyway. I just hate to miss seeing the flowers. Binoculars or a telephoto, I guess.
