Best Passionflowers for pots in northern climates
What Passifloras grow and bloom the best in pots indoors most of the year and outdoors for 3-4 months during summer? I have tried several kinds and have only had success with P. x belotii, which I am very impressed with. Passiflora x belotii blooms nearly all year indoors and outdoors. I have grown several others but eventually tossed them out. P. caerulea grew like crazy for several years and never bloomed, P. coccinea never grew at all and eventually died, and P. "Incense" grew very well but only had 2-4 flowers a year. I would love to grow more kinds of passionflowers but don't want to waste my time (and limited space) trying to grow ones that won't perform.
