Passiflora edulis 'Red Flamenco' is a vigorous hybrid cultivar valued for its large crops of sweet, purplish-red fruits with excellent flavor and intense fragrance. Native to South America, this evergreen climbing vine thrives in warm climates and is cold-tolerant enough to survive brief light frosts. Seeds have a hard outer coat that requires pre-treatment to achieve good germination rates and uniform sprouting.
Before sowing
Scarification followed by warm water soaking is most effective. Seed freshness is critical; fresh seeds germinate in 10-20 days while older seeds may take months. Remove all pulp residue before treatment to prevent fungal growth.

What to expect
Tips
For best results: (1) Use fresh seeds extracted from ripe fruit—these germinate in 10-20 days versus months for stored seeds; (2) Maintain consistent warmth at 22-29°C using a heat mat if needed; (3) Scarify seeds gently to avoid damaging the embryo; (4) Keep soil moist but not waterlogged to prevent fungal issues; (5) Do not let seedlings dry out completely; (6) Use transparent covers to maintain humidity during germination; (7) Once germinated, provide 6-8 hours of indirect sunlight daily; (8) Transplant seedlings into larger pots when they develop 2-3 true leaves; (9) Provide strong support structure (trellis, fence) early as vines grow vigorously.
