I've always wanted a red one ( This year I think I'll get one) I have plenty of this one which blooms quite a bit ( passiflora incarna?) I have a big one that went from my trellis to across my fence which was about 10ft. Blooms very nicely summer/fall and the hummingbirds love it!
My red passion flower bloomed profusely last summer. I just gave it a couple shovelful of compost and always kept it well watered. It gets afternoon shades. It died back in our mild winter and it's coming back already. This is mid February, we're not safe from cold snap just yet so I'm going to protect it. Hope my experience will gets yours to bloom this summer. They're quite a sight when in bloom. They look like my red tropical water lilies.
