Passionflowers are exotic looking vines that make your heart race. I have grown a number of these beauties, all of which have been in the passiflora species. Most varieties are native to subtropical or tropical regions but there are a few that are cold hardy to Zones 6 and 7. Given that I garden in Zone 5, I grow passionflowers in pots and move them inside when the temperatures start to drop. I prune the vine back to 6” to 8” and then place the pot in a sunny window until after danger of frost in the spring. NOTE: the passiflora species sets its flower buds on new wood, so the time to prune them back is in fall or late winter. Some passionflowers have delicious fruit; others not so much. Passionflowers grow quickly and have dense foliage. Longer-stemmed varieties make great privacy screens for outdoor entertainment areas. Most passionflowers bloom from late spring into fall, with flowers lasting only one day (similar to Daylily and Hibiscus).
