Passionflower ( P. caerulea ) is a rampant grower once established. It is rarely the best variety for pot cultivation after a couple of years or so.
Given the right site and planted in the ground with room to spread, it will reward you with flowers all thru summer and into Autumn.
My passion flower climber growing perfectly well till 3 days ago has started wilting. Did anyone discover what the root cause was?
I am simply guessing, but I think it is very like clematis wilt,and since we have had hot humid weather followed by a lot of rain, I think that a fungus has taken hold. I have cut mine down to the ground and hope it will recover. Fingers crossed...
