Our mystery seeds from last week were tepary beans, Phaseolus acutifolius.
Tepary bean plants look like any other bean, but they have slightly finer leaves. Even though they look delicate, these hardy tepary beans can grow under the most stressful conditions where most other plants whither away. Their main characteristic is that they are incredibly drought tolerant. Tepary beans only need one rain to germinate. The roots reach deeper into the soil than other beans, so tepary beans can produce fruit with very little moisture. In fact, overwatering inhibits seed production.
The wild types are often light to dark pink.
The beans themselves come in a variety of colors, including brown like these, rust, beige,
white, and as you can see from a nonprofit organization that sells them, Native Seeds, a variety of other colors.
The beans have a low glycemic index and are high in fiber.
Have you ever grown or eaten tepary beans?
