I was given a Passiflora vine about 4yrs. ago. I am not aware of which one it is. The zone here is 7b. The vine usually dies back from cold to within 4-5feet of the ground. I have it in a south facing location, protected. It grows atleast 10-12ft in summer, but have yet to see a bloom.

Have restricted water, fertilizer, trying to see what might work to get it to bloom.

I have a few less hardy ones that I keep in pots through out the winter and they perform very well for me.

Any assistance appreciated.
