Seedling
3-4 weeksTender young plants with 2-4 true leaves, delicate stems emerging from soil
Keep soil consistently moist but not saturated. Provide bright indirect light. Harden off transplants before moving outdoors. Protect from frost.
Vegetative Growth
6-10 weeksRapid vine expansion with heart-shaped leaves developing along stems, tendrils forming for climbing
Provide sturdy support structure or trellis. Water regularly during dry periods. Remove damaged or diseased foliage. Light fertilizing with balanced formula can support growth.
Flowering
8-12 weeks, with repeated bloom cyclesProduction of spectacular 2-3 inch flowers with white and purple corona filaments, prominent central structures, and fragrant blooms
Continue regular watering and support vine growth. Flowers are self-fertile. Do not over-fertilize or excess foliage will develop at expense of blooms. Enjoy multiple flushes of flowers from mid-summer to frost.
Fruiting
4-6 weeks after floweringSmall yellow-green egg-shaped fruits develop after flowers fade, reaching 1-1.5 inches in length
Fruits are edible with granadilla-like flavor when fully mature (yellowish). Allow fruits to fully ripen on vine for best flavor. Support heavy fruit-laden branches if needed.
Dormancy
3-4 months (November-March in northern zones)In colder zones (5-7), vines die back to ground after frost; roots survive winter underground and resprout in spring
Cut back dead foliage to ground level after first hard freeze. Mulch around base with 2-3 inches of compost or leaves for winter protection. In warmer zones, vines may remain semi-evergreen.

Harvest Tips
Flowers are enjoyed for their ornamental beauty primarily. Fruits can be harvested when fully yellow/orange, typically 4-6 weeks after flowering. Pick fruits gently or allow them to drop naturally when ripe. For medicinal use, harvest leaves and stems just before flowering peaks in mid to late summer, dry in bundles in shade, and store in airtight containers. Make tea by steeping 1-2 teaspoons of dried herb in 8 oz hot water for 5-10 minutes.

- 🌱 Gulf Fritillary butterflies have evolved a special relationship with passionvines—they lay eggs exclusively on Passiflora species, and the caterpillars sequester toxic plant compounds to make themselves poisonous to predators.
