Permaculture uses
The tuber is a staple food crop in many tropical regions after proper processing to remove calcium oxalate crystals. It can be used in curries, stews, or fried. Some cultivars are less acrid than others. It also has medicinal applications, particularly in traditional medicine for its anti-inflammatory and digestive properties. In permaculture, it serves as a large, productive tuber crop suitable for humid climates.
Permapeople description
Amorphophallus paeoniifolius, also known as elephant yam, is a tropical tuber crop grown primarily in Asia. It produces a large underground corm that is edible after proper preparation to remove toxins.
Botanical description
Amorphophallus paeoniifolius is a tropical tuberous herbaceous plant. It possesses a large, underground corm that can weigh several kilograms. A single petiole emerges from the corm, supporting a highly dissected, umbrella-like leaf that can reach impressive sizes. The inflorescence is a large spadix surrounded by a spathe, similar to other Amorphophallus species. The spathe is typically greenish-purple, and the spadix emits a strong, unpleasant odor to attract pollinators. After pollination, berries develop, turning red when ripe.
Companion planting
Specific companion planting information for Amorphophallus paeoniifolius is limited. However, given its large size and shade-casting ability, consider planting it alongside shade-tolerant crops. Avoid planting it too close to crops that require full sun. Intercropping with legumes could potentially benefit the yam by fixing nitrogen in the soil.
Propagation methods
Propagation is primarily achieved through division of the corm. Small offsets or bulbils that develop around the main corm can be separated and planted. Seed propagation is also possible, although it is a slower process and may not produce plants true to type.
History and traditions
The Elephant Foot Yam has a long history of cultivation in Southeast Asia and the Pacific Islands, dating back centuries. It has been used as a food source during times of famine and plays a role in various traditional ceremonies and festivals. In some cultures, it is believed to have medicinal properties and is used to treat a variety of ailments.
Usage calendar
Planting typically occurs during the early rainy season (e.g., April-May in some regions). The plant grows vegetatively during the wet season. The corm is harvested during the dry season (e.g., November-December), after the foliage has died back. Flowering occurs sporadically, often before leaf emergence.
