Tepary Bean

Integral to indigenous cultures of the Sonoran Desert, the tepary bean holds significance as a traditional food source and is known by various indigenous names such as "Pawi," "Escomite," and "Yori mui." It continues to be celebrated in regional cuisines and is gaining recognition in specialty food markets.

• The tepary bean can mature with as little as 250 mm of annual rainfall, showcasing exceptional drought tolerance.
• Its seeds store well when dried, maintaining a shelf life comparable to other pulses.
• Modern cultivars were developed in the late 20th century to enhance yield and adaptability.
• It is prized for a nutty flavor and firm texture, with a low glycemic index beneficial for health-conscious diets.
• Regional names include the Spanish "frijol tepari" and indigenous terms reflecting its cultural roots.

Tepary bean plants grow as semi-vining annuals with slender stems and trifoliate leaves. Their pods range from 5 to 10 centimeters long, each containing several small, oval seeds that come in white, tan, brown, or black hues. The plant exhibits strong drought tolerance and resistance to certain fungal pathogens, though it is susceptible to root rot in humid conditions. Seeds store well when dried, ensuring longevity comparable to other pulses.

Consumed primarily in dried form, tepary beans are valued for their nutty flavor and firm texture. They feature in traditional southwestern U.S. and Mexican dishes such as stews and soups. Nutritionally, they offer high protein and fiber content with a low glycemic index, appealing to health-conscious consumers. While commercial availability remains limited, specialty producers in their native regions are expanding access to dried beans and related products.

While the tepary bean is largely maintained as landrace varieties, modern cultivars have been developed by the USDA and the University of Arizona in the late 20th century to improve adaptability and yield under drought conditions. Specific cultivar names are less commonly referenced, reflecting its traditional and regional cultivation history.

Tepary beans require well-drained soils and perform best in hot, dry environments with minimal irrigation. They can mature with as little as 250 mm of rainfall annually. Avoiding humid conditions is important to reduce susceptibility to root rot. Their semi-vining habit may benefit from support or trellising, though they can also be grown in bushier forms.

Dried tepary beans store effectively for long periods when kept in cool, dry conditions. Proper drying before storage is essential to maintain seed viability and prevent spoilage. Their shelf life is comparable to other dried pulses, making them suitable for long-term pantry storage.
