The story
Fava beans fed the Mediterranean and Middle East for 8,000 years, before common beans arrived from America; Egypt's ful medames and Rome's spring fava with pecorino are both older than the empire. It grows in cold weather and fixes nitrogen.
Planting
Full sun, any soil; sow seed directly in late winter or early spring in cold climates, in autumn in mild ones, 2 inches deep, 6 inches apart.
Growing
Water in dry spells; no feeding. Pinch the growing tip when flowering starts to deter black aphids. Stake in windy sites.
Harvest and use
Pick small pods whole, or shell plump pods in late spring; pop the beans from their skins after blanching. Dig the roots in to feed the soil.
What to watch for
Black bean aphid, chocolate spot in wet weather, and heat, which ends it.
