Description

A fast-growing vine with semi-lobed leaves. Vines may grow many feet in a single season.

Hardiness

Exact hardiness unknown. Probably hardy to frosts and some sources claim hardiness as low as 15-20F.

Growing Environment

Grow in full sun or part shade. Water regularly. Once established it is extremely fast-growing.

Propagation

By seeds, which can take weeks to a few months to sprout. Seeds should be planted in warm soil and soaked for 24-48 hours in warm water prior to planting. Giberrelic acid treatments helps as well. Also propagated by stem cuttings.

Germination Info

It is recommended to pretreat Passiflora seeds before planting. They contain a hard seed coat and are very slow to sprout. There are various pretreatment methods, but the simplest is 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 1/2-1" deep in moist, sterile soil. Keep soil temperature consistent at 70-85F, with some day/variation in this range. 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. Some seeds can take up to 12 months to sprout.

Uses

Grown as an ornamental for its pretty flowers.

Native Range

Native to the Americas. It also grows wild in parts of Southern Florida.
