Peta Muni is a rare cowpea cultivar from the Guarijio people of the Rio Mayo watershed in Sonora, Mexico, where it has been grown for generations in both dry-farmed mountain slopes and irrigated floodplains. This vigorous climbing variety was traditionally variable in appearance, but modern seed stocks show remarkable uniformity. It's a living connection to indigenous Mexican agriculture, preserved through the Native Seeds/SEARCH Seed Bank Collection and worth growing for both its cultural heritage and its enthusiastic vertical growth habit.

Originally called Yori Muni, this cowpea emerges from one of Mexico's most biodiverse regions and carries the agricultural knowledge of the Guarijio people. Its climbing nature makes it a natural choice for trellising, transforming a utilitarian crop into an ornamental garden feature. The uniformity of modern seed stocks means you'll get consistent plants despite the variety's historic tendency toward shape and color variation, offering reliable harvests from a genuine heirloom source.
As a cowpea, Peta Muni produces edible pods and mature seeds used in traditional Mexican cuisine and throughout the cuisines of the American Southwest. The fresh pods can be harvested young for cooking as a green vegetable, while mature, dried seeds are prepared as a protein-rich staple in soups, stews, and bean dishes. The variety's vigor and climbing habit also give it ornamental value in gardens where productive plants double as landscape features.

Direct sow Peta Muni after the last frost date when soil has warmed to at least 60°F, planting seeds near the base of your trellis or support structure. Space plants 4-6 inches apart along the trellis line.
For fresh pods, harvest when they reach 3-4 inches long and are still tender and bright green, typically 60-70 days after planting. Snap pods from the vine by holding the stem and gently pulling the pod downward. For dried seeds, allow pods to mature fully on the vine until they turn brown and papery, then harvest and shell out the seeds for storage. Regular harvesting of young pods encourages continued flowering and production.
Peta Muni's climbing habit means minimal pruning is needed; instead, train vines onto trellising as they grow. Remove any damaged or diseased foliage as it appears, but avoid heavy pruning that would reduce flowering and pod production.

“Peta Muni originates in the Rio Mayo watershed of Sonora, Mexico, where the Guarijio people have cultivated this cowpea as part of their traditional food system. Known locally as Yori Muni, the variety was historically grown across the watershed's varied terrain, adapted to both dry-farmed slopes and irrigated floodplain conditions. Early documentation noted its variable character in shape and color, reflecting the natural diversity of seed-saving populations in indigenous communities. The variety was preserved through Native Seeds/SEARCH's Seed Bank Collection, ensuring that this crucial link to Guarijio agricultural heritage remains available to gardeners and farmers today.”
