Description
A giant aroid that grows an enormous, single pinnate leaf on a thick, fleshy stalk from a huge, bowl-shaped tuber, about 30 cm (1 ft.) in diameter. When the leaf wilts in Winter or the dry season and the plant goes into dormancy, the tuber can be dug up and stored dry. Before a new leaf is produced, mature plants can sprout a giant, maroon inflorescence that is truly a spectacular sight, but emits a rather unpleasant smell. This giant aroid has been cultivated for centuries in the Indopacific region for the edible tuber and its native origins are obscured today.
Germination Guide
🌍 Island Southeast Asia, from India to New Guinea and Northern Australia
Difficult
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.

Growing 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.
