Alibertia patinoi, commonly known as borojó, is a dioecious tropical rainforest tree native to the Chocó-Darién moist forests ecoregion of northwestern Colombia and Ecuador. Seeds are recalcitrant with no dormancy, exhibiting rapid germination (mean time of 13.4 days) under warm, humid conditions characteristic of its natural tropical forest understory habitat. The species is adapted to shaded conditions and exhibits low germination requirements.

What to expect
Tips
Seeds are highly susceptible to rot if substrate becomes waterlogged; maintain high humidity (85%+) without saturation. Place seedlings in bright, filtered light without direct sunlight exposure. Use freshly harvested seeds with 44% moisture content for optimal viability (up to 97% germination rate). Keep substrate consistently moist but well-draining. Never allow seeds to dry out as they are recalcitrant. Gradual acclimatization to outdoor conditions essential before transplanting. Optimal germination occurs at 25-28°C with constant high humidity.
