Apios americana (American groundnut)

Quantity

This is a native plant. Tubers are edible raw or roasted with a pleasant flavour likened to roasted sweet potatoes, They can be dried and ground into flour to use as a thickener or mixed with other flours in baking. Tubers are very high in protein (17% crude protein); more than 3 times that found in potatoes. They only gain a reasonable size after 2-3 years. Best managed as a permaculture colony, harvesting portions of the tuber-chains each year. Pods of Apios are only edible when still young (green, smallish). The plant is a legume and fixes nitrogen in the soil, therefore doesn't necessarily require fertilizer, but as it is a heavy feeder, a little organic fertilizer will help it. Tubers can be harvested at any time of the year but are at their best in the autumn and will store until at least the spring.
