How to grow and care for Passiflora

Passionflower propagation can be achieved by seed or stem cuttings in spring, or by layering in late summer. Propagating Passion Flower Seeds Passion flower seeds germinate best when fresh or directly from the fruit. They do not store well and will usually be dormant for up to a year. To break dormancy and improve germination of seeds that have been stored for a while, you can simply take a piece of fine sandpaper and lightly rub one or both sides of the seeds. Then soak the seeds in lukewarm water for about 24 hours. Throw out any seeds that float, as they are no good. AD Press the remaining seeds about ¼ inch (0.5 cm) into moist potting mix or peat compost – whatever you use should drain well. Cover with vented plastic to retain moisture and remove when germination begins in two to four weeks. (Note: Older seeds can take anywhere from four to eight weeks or even longer to germinate.) Keep the plants out of direct sunlight until they develop their second set of leaves. Don’t expect instant blooms with seed-grown plants. Some passion flower species can take up to ten years to flower. How to Root Passion Flower Cuttings Stem cuttings are normally taken during the conifer stage, when they can easily break off when bent. Use a pair of sharp pruners and cut off about cuttings just below the node. Peel off the bottom leaves and tendrils, then dip the ends in rooting hormone. Stick the cuttings about half an inch (1 cm) into well-draining potting mix or an equal mix of sand and peat. Water lightly, then cover with a clear, vented plastic bag. Include stitch support if needed. Place the cuttings in a shady place, keep them warm and moist. You should notice new growth within a month, at which point you can gently pull the cuttings to test for root establishment. Once significant root formation has occurred, they can be transplanted to their permanent locations.
