Pigeon pea is a nitrogen-fixing, perennial shrub, growing to 4 m in height, that produces green or dry seed in seasonally dry climates. Pigeon peas are adaptable to many soil types and are used as a dry pea, green vegetable, fodder, fuelwood, green manure or cover crop.

'Black' pigeon peas have historically grown very well at ECHO Florida. They produce black seeds and like other pigeon peas are perennial shrubs that produce green or dried beans in seasonally dry climates.
