Phaseolus acutifolius. A traditional bean from Ures in central Sonora, sometimes grown on marginal land because of its heat and drought resistance. The locals told us it produces as much if grown in spring (planted March and harvested late June) as summer (planted July-Aug and harvested in November). From our Seed-Bank Collection. Warm season planting Origin: Low Desert, about 1400' elevation Habit: some twining but not a vigorous climber Approx. 6g/50 seeds per packet. Limit 3 packets. *Tepary beans grow best in hot, dry regions with minimal water or irrigation. Overwatering (in any climate) will cause the plants to look very leafy and healthy, but they'll produce few, if any beans. If grown out of region, which is the desert Southwest, results may vary.
