Moctezuma Bean is a white tepary bean with a fascinating origin story: it was collected in 1976 directly from Moctezuma Market in the Moctezuma watershed of Sonora, Mexico, and has been preserved through Native Seeds/SEARCH's seed bank ever since. This vining variety thrives in hot, arid climates and earned recognition for its exceptional productivity in Tucson trials. As a member of the Phaseolus acutifolius species, it represents an ancient crop perfectly adapted to desert conditions and well worth growing if you have the heat and space to let it climb.

This bean was rescued from a market in Mexico and kept alive by seed savers for nearly 50 years, making it a direct link to traditional Sonoran agriculture. The 1976 collection at Moctezuma Market gives it genuine historical weight; it's not just another bean, but a specific moment in time preserved in seed form. It performed exceptionally well in Tucson growing trials, proving its reliability in hot climates where many other beans struggle.
As a dry bean, Moctezuma Bean is harvested fully mature and used in traditional Sonoran cooking. The dried beans can be cooked for soups, stews, and refried bean preparations. Given its tepary heritage, it likely handles drought stress during growth, making it valuable not just as food but as a demonstration of how traditional crops adapt to challenging climates.

Direct sow seeds into the garden once soil has warmed thoroughly and all danger of frost has passed. Tepary beans germinate and grow best in warm soil conditions.
Allow pods to mature fully on the vine until they dry and turn brown or papery. Harvest when pods are completely dry and seeds rattle inside; this typically occurs well after fresh-eating stage. Shell beans by hand once fully dry and store the white seeds for later cooking or replanting.
As a vining bean, Moctezuma Bean benefits from training onto trellises or poles rather than pruning. Guide young vines onto support structures as they emerge, allowing them to climb naturally. Minimal pruning is needed; focus on removing any dead or diseased growth if it occurs.

“Moctezuma Bean has a precise and humble origin: in 1976, Native Seeds/SEARCH collected this white tepary from Moctezuma Market in the Moctezuma watershed region of Sonora, Mexico. The variety was then preserved in NS/S's Seed-Bank Collection, where it has remained available to gardeners and growers ever since. This isn't a bean with centuries of family lore, but rather a modern example of seed rescue work: someone recognized its value in a marketplace, collected it, and ensured it wouldn't disappear. The 2020 growing trials in Tucson demonstrated its continued vigor, showing that nearly 45 years after collection, this bean remains productive and reliable.”
