Iron and Clay Cowpeas are heat- and drought-tolerant legumes. They are adapted to a range of soils and seem to be relatively pest-free. Like all cowpeas, they can also be consumed by humans in the form of snap beans and dry beans. Iron and Clay have a long season of vegetative growth before flowering and will make vines that will run along the ground or climb up other plants, if given the chance. Seeding rate was 54 pounds per acre.
