What the research guides add
Tepary is the opposite of a fussy bean: it was bred by desert farmers, and the USDA guide is clear about what it tolerates.
- A native annual legume; domesticated plants are bushier than wild vines, up to 12 inches tall and 20 inches across, with seeds about ⅓ inch long in brown, beige, black, mottled or white. (USDA NRCS)
- The flowers can produce viable pollen and set seed at temperatures above 105°F, and the leaflets tilt parallel to the sun’s rays to reduce heat load. (USDA NRCS)
- Roots extend deep and can extract soil moisture that common bean cannot reach; the plants complete their reproductive cycle rapidly, which avoids later drought. (USDA NRCS)
- In the Southwest deserts it is traditionally sown at the start of monsoon rains (mid-June to mid-July), and can be sown earlier with supplemental irrigation. (USDA NRCS)

How this guide is put together
The growing data on this page — sowing windows, pests, diseases, soil and site requirements — comes from named horticultural sources, listed in References below, checked against RHS and Met Office guidance. An automated pipeline assembles that verified data into the page you're reading: it selects which facts to lead with and builds the surrounding prose and layout. It does not invent a date, a source or a number — where a verified value for a field isn't available, the page leaves it out rather than guessing. A person reviews and publishes each page; nothing goes live unverified.
