Usually, passion flower seeds do not store well and will go dormant for up to a year. Therefore, passion flower seeds sprout most easily while they are fresh or straight from the fruit. For seeds being stored a while, you ought to rub one or both sides of the seeds lightly with a piece of fine sandpaper to break dormancy and improve germination. Then, the seeds should be steeped in lukewarm water for about 24 hours. This also helps to check the germination possibility of passion flower seeds because floating seeds are hard to sprout. You had better throw out these seeds.

After break dormancy and improve germination, prepare moist potting mix or peat compost – both should drain well – and press the remaining passion flower seeds into about ¼ inch. Remember cover with ventilated plastic to keep them humid. After two to four weeks, remove the plastic when the seeds begin to sprout. This may take longer for older seeds, from four to eight weeks or even longer.

Another thing you should pay attention to is keeping seedlings out of direct sunlight until passion flower sprouts develop their second set of leaves. Seed-grown plants do not bloom instantly, in some case, you have to wait up to ten years for them to bloom.

Another popular way to propagating passion flower is to root their cuttings. You should stem cuttings during the softwood stage, when they can break off easily when bent. Clip about 4- to 6-inch cuttings just below the node with a sharp pair of pruners. Then, strip off the bottom-most leaves and dip the ends in rooting hormone. Prepare well-draining potting mix or sand and peat mix with the equal amount and stick the cuttings about half an inch into. Cover them with a clear, ventilated plastic bag after water lightly. You may need stick supports.

The way to Propagate Passion Flowers by Layering

Besides rooting vine cuttings and growing seeds, passion flowers can be propagated by layering in late summer. To propagate passion flowers by layering, strip the leaves from a small section of the stem and bend it over. Then, bury the piece of stem partially in the soil and anchor it in place with a small stone if necessary.

The piece should begin rooting within a month providing it get enough water. However, the piece should be kept in place in longer time, throughout fall and winter and then removed from the mother plant in spring for better rooting and developing.
