Bomarea multiflora is a climbing vine native to the Andes cloud forests of Colombia and Ecuador, belonging to the Alstroemeriaceae family. This species benefits from warm-cold stratification cycles that break dormancy and mimic natural seasonal changes in its high-altitude native habitat. Seeds must have their red sarcotesta layer removed, as this coating inhibits germination; fresh or recently stored seeds often germinate more readily.
Before sowing
For best results, especially with stored seeds: Soak seeds in warm water for 24 hours, then place in moist vermiculite or peat and refrigerate at 4-8°C for approximately 6 weeks. This warm stratification (20-25°C) for 2-4 weeks followed by cold stratification mimics the plant's natural alpine seasonal dormancy and significantly improves germination rates.
Sowing
What to expect
Tips
Seeds must remain moist throughout germination—avoid drying out completely. Keep substrate moist but never waterlogged. Use artificial lighting if natural light is insufficient; bright light is acceptable once germination begins. Open transparent lid every 2-3 days for air circulation to prevent fungal growth. Germination is often erratic and may take 2-3 months; some seeds may wait for spring. Once seedlings develop 3-4 leaves, transplant to 8cm pots individually. Grow on for one year before repotting to larger containers. Species develops tuberous roots early, so handle seedlings carefully during transplanting. Growth is initially slow but accelerates once established in larger containers.
