The story
Bambara groundnut is West Africa's own peanut, grown by women farmers from Senegal to Nigeria for 4,000 years on soils too poor for anything else; it buries its pods like a peanut and feeds families through the hungry season.
Planting
Full sun, sandy drained soil, heat, and a 120-day season; sow seed after the soil warms, an inch deep, 8 inches apart.
Growing
Water little; it survives drought that kills cowpeas. Hill soil lightly around the plants. No feeding.
Harvest and use
Dig the whole plant when leaves yellow in late summer; the round pods are boiled fresh or dried for stews and flour.
What to watch for
Wet soil, and the short day length it needs to set pods.
