Amorphophallus paeoniifolius, commonly known as Elephant Foot Yam or Whitespot Giant Arum, is a tropical tuberous perennial native to Island Southeast Asia. Seeds are non-dormant but have poor viability and should be sown fresh immediately after collection. Germination is highly variable, typically occurring between 3 weeks to 8 months at warm temperatures, requiring consistent moisture and warmth.
Before sowing
Seeds are non-dormant and lose viability quickly; sow fresh seeds as soon as possible after harvest
Sowing
What to expect
Tips
Sow fresh seeds immediately as they lose viability quickly. Seal pot in plastic bag to maintain high humidity and consistent moisture. Maintain temperatures between 24-26°C for optimal germination. Use a heat mat for stable warmth. Place in bright, indirect light. Germination can be sporadic—do not discard pots if germination is delayed. Transplant seedlings into individual pots once they develop their first leaves. Seedlings will require greenhouse conditions for at least 2 years before planting out. Avoid waterlogged soil to prevent rot.
