Stelechocarpus burahol, commonly known as Kepel or Burahol, is a rare tropical fruit tree from the Annonaceae family native to the humid evergreen forests of Java, Indonesia, historically reserved for Javanese royalty. The species exhibits challenging hypogeal germination requiring deep root development before any visible leaf emergence, with the process typically taking 6-12 months or longer. Its distinctively aromatic fruit has made it culturally and botanically significant across Southeast Asia.
Before sowing
Seeds should be extracted from mature fruits and cleaned by washing, then dried under shade before scarification and soaking. Sow seeds as soon as possible after extraction to ensure maximum viability
Sowing
What to expect
Tips
Use deep containers (minimum 40 cm) to accommodate the swollen taproot and ensure drainage. Maintain constant temperature of 26-30°C and high humidity using a transparent pot lid; open lid every 48 hours for air exchange. Use filtered light or fluorescent lighting; avoid direct sunlight. Sow seeds immediately after extraction from mature fruit for highest viability. Expect no visible leaf emergence for 6 months or more; continued moisture and warmth are essential. Keep substrate consistently moist but not waterlogged. At the 3-5-leaf stage, carefully pot up seedlings into fresh substrate. Transplant seedlings when reaching 30-40 cm height. Provide protection from frost and strong winds. Young seedlings benefit from partial shade and high humidity (above 70%) until well established.
