Elephant Foot Yam
Amorphophallus paeoniifolius
Elephant foot yam is a tropical perennial grown for its large starchy corm, which can reach 50 cm across and 9 kg after three years, plus cooked young leaves and stems. The raw corm is toxic - calcium oxalate crystals puncture the mouth and tongue - so thorough cooking or full drying is required before it is eaten. Reaching a harvest takes three full growing seasons rather than one, and cultivated forms of the same corm also make a substantial pig feed.
