Passiflora caerulea

Passiflora caerulea, the blue passionflower, bluecrown passionflower or common passion flower, is a species of flowering plant native to South America. It has been introduced elsewhere. It is a vigorous, deciduous or semi-evergreen tendril vine growing to 10 m or more.

It can easily grow 20 feet or more a year. Prune the vines in the early spring to control growth, promote lush foliage, and increase flower and fruit production. The vine's flowers, which bloom for only one day, do not need to be deadheaded.

caerulea, has edible Passion fruit. They are edible when ripe (going from green to orange yellow) but are usually insipid though some are tastier than others. Note Always let any Passion fruit drop rather than trying to pull them off. Some Passion fruit are toxic, even some of the edible ones may be when unripe.
