Answer: There are about 400 subspecies of Passiflora identified but only about 35 that are commonly grown. Of those, only Passiflora alatocaerulea is root hardy in your gardening region. The plants will grow in full sun to part shade in deep, moist, well-draining soils with a pH level of 6.0 - 8.0. Soil that is too rich will produce abundant foliage and few blooms.
You can take root divisions of your plant to propagate, or save the seeds and plant them. To divide, simply unpot the plant and cut it into divisions, each with roots and vining stems. Repot each division and by Christmas they should each have become established in their new pots.
Good luck in your venture!
