The seeds themselves are striking, with their deep black color serving as both visual appeal and a marker of this variety's distinctive character among cowpeas.

These seeds carry real provenance, passed hand to hand from a Native American grower in Bisbee to a truck driver to dedicated seed savers, landing them in the Native Seeds/SEARCH Seed Bank Collection. They're remarkably productive in the low desert environment where they originated, yielding generous harvests without fussiness. Black cowpeas are a staple legume with deep roots in American foodways, and this particular strain holds the story of how seeds survive and travel through the generosity of gardeners and foragers.
Bisbee Black Cowpeas are cooked as a fresh or dried legume, traditionally prepared in soups, stews, and rice dishes throughout the South and Southwest. The dried black seeds hold their shape well during cooking and develop a slightly earthy, satisfying flavor that anchors hearty comfort food. They can be shelled fresh for succotash-style preparations or left to mature fully on the plant for drying and long-term storage, offering flexibility in how and when you harvest.

Direct sow seeds outdoors when soil temperature reaches 70-85°F and all frost danger has passed. Plant seeds about 1 inch deep, spacing them 6-8 inches apart in rows 18-24 inches apart.
Harvest fresh pods when they reach full size but while still tender, typically 60-70 days after planting. For dried cowpeas, allow pods to mature fully on the plant until they brown and dry completely, then shell the black seeds by hand. Store dried seeds in a cool, dry place for year-round use.

“The Bisbee Black Cowpea's story began in Bisbee, Arizona, where a Native American grower cultivated these black-seeded cowpeas adapted to the region's harsh climate. The seeds passed through the hands of a truck driver, who recognized their value and shared them with James Cowan, a member of Native Seeds/SEARCH in Missouri. From there, they entered the NS/S Seed Bank Collection, where they've been preserved and distributed to home gardeners and farmers who understand the importance of maintaining regional varieties. This lineage reflects how heirloom seeds survive not through institutional preservation alone, but through networks of growers willing to save and share.”
