Information on Passion Flower Seeds

Overview

Passion flower seeds produce vigorously growing vines, which are native to the tropical areas of the world. They develop inside edible fruits that set in early summer after the first spring flush of blooms, and again in the fall. The seeds are about 6 millimeters (about 1/4 inch) long and are covered with crater-like formations all over its surface.

About Passion Fruit

While all cultivars of passiflora produce edible fruit, the ones that produce crops that are popular among consumers is the Passiflora edulis. The seeds can be found in the 1 1/2- to 3-inch-long fruits, and can be planted to grownew vines. Passion fruit is a major agricultural crop in Brazil, Australia, Hawaii, and South Africa. Passion fruit vines produce fruit from late summer through autumn, especially in southern states.

Weed

In certain states of the U.S., there are passiflora cultivars that have become invasive or weedy. For example, according to the USDI Geological Survey, Passiflora edulis, Passiflora laurifolia, Passiflora ligularis and Passiflora suberosa are invasive in Hawaii, while Passiflora foetida and Passiflora biflora are weeds in Florida. While the majority of the weed passion vines sprout from perennial rootstock, passion vine also spreads through the wild by the seeds in the fruit.

Pollination/Fertilization

Passion flower is insect-pollinated, primarily by bees. The sticky pollen catches on their bodies and is transported as the bees travel from flower to flower. Passion flowers can also be hand-pollinated, though the yellow blooming passion vines are self-sterile. This means that if the flower receives pollen from their own plant, it will not develop into seeds and fruit.

Harvest

Seeds from the ripe fruit can be cleaned, dried and stored for a short time before planting. However, the seeds will not last longer than a year, so they should be planted as quickly as possible. Animals and birds that eat passion fruit clean and transport the seeds in their systems, and deposit them along with their fecal matter for fertilizer, often near bodies of water where they go to drink. This provides the new passion vine with the optimal place to grow.

Planting

Plant seeds in the spring after danger of frost. Plant in partial shade and keep the soil moist through germination. Seeds sprout 10 to 20 days after being sown, and the young plant will grow quickly. Avoid planting seeds near waterways or on slopes leading to waterways, as this provides passion vines the ideal opportunity to travel downstream and sprout as weeds.
