Answer: You didn't mention which species of passionflower you have, but I'll assume it's the one most commonly grown as a houseplant -- Passiflora caerulea. This plant likes a rest period during the winter to develop its flowers. During this time, keep your plant in a cool (50 degrees F) location and water it only enough so that the root ball doesn't dry out. It may lose its leaves, but that's ok. Then begin frequent watering and fertilizing in March. Young plants also benefit from being repotted yearly. I hope this helps!
