Passionflower is a fast-growing evergreen climber from South America. The flowers emerge in summer and are stunning and exotic. Bowl-shaped, white with blue centers, they bloom repeatedly through the fall. The yellow-orange fruit is edible but not particularly tasty.
This fast-growing vine is one of the most hardy passionflowers, and tolerates many soil types.
It prefers full sun.
Grow it a trellised container, or against a wall in a mixed border.
Also can be grown as indoor plant in coller climate regions.

General propagated from seeds which show widely variable germination rates, from a few weeks to months.
Longer germination times are seen particularly if conditions are not ideal.
It is recommended to soak the seeds for 24-48 hours in warm to the touch water, just prior to planting. Optionally, seeds can be lightly scarified with sand paper to provide some permeation on the seed coat.
Once pretreated, plant seeds 15-20 mm deep in moist, sterile soil. Seeds like bottom heat of +20-22C for faster germination. Cool soils will significantly delay seed germination time if not inhibit germination altogether. Standard room temperature can be too cool for proper germination.
Estimated germination time under optimal conditions: 6 weeks to 6 months.
Once sprouted, the vines usually produce by the first year.
