Tepary Bean (Phaseolus acutifolius)
What is the Tepary Bean?
The Tepary Bean is an ancient bean variety from the legume family (*Fabaceae*) and belongs to the genus *Phaseolus*. Its botanical name is Phaseolus acutifolius, referring to its pointed leaves. It originates from the hot, arid regions of northern Mexico and the south-western United States and is particularly well adapted to drought and poor soils.
Origin & History
The Tepary Bean has been cultivated for centuries by indigenous peoples such as the Tohono O'odham, Pima and Mixtec communities – always in places where other cultivated beans could not survive. Its ability to thrive under extreme drought makes it highly relevant again today: as a climate bean for modern, resource-conserving cultivation.
Special Characteristics
- Extremely drought-tolerant – ideal for poor, sandy soils and hot sites
- Very high in protein – a valuable source of protein for the diet
- Short growing season – matures quickly, often in just 60–75 days
- Sturdy bush bean – grows low, compact and without plant support
- Various seed colours – including black, white, beige or speckled
- Versatile – delicious boiled, roasted or soaked
Tepary Beans in the Garden
In cultivation, Tepary Beans prove easy-care and undemanding. They prefer full-sun, warm sites with well-draining soil. Particularly advantageous: they need very little water and no plant support. This makes them the ideal choice for dry sites, climate-resilient gardens or self-sufficiency gardens with limited irrigation options.
