The Zia Pueblo Chile Pepper is a traditional landrace Capsicum annuum native to Zia Pueblo in northern New Mexico. It is known for its sweet flavor that develops bitter-sweet notes when ripe and heat levels averaging around 20,500 SHU, making it one of the hotter native New Mexico chiles. Grown at high elevations around 5,500 feet, these peppers are valued for roasting, stuffing, and drying.

The Zia Pueblo Chile Pepper is an ancient landrace variety developed over centuries by farmers at Zia Pueblo, a Keres-speaking community near the Jemez River in northern New Mexico. Seeds were collected in the mid-1990s from an elder farmer by Native Seeds/SEARCH and later evaluated in New Mexico State University trials. The pods measure approximately 3 to 5 inches long and 0.8 to 1.5 inches wide, starting green and ripening to a bright red with medium-thin flesh. Plants grow 2 to 3 feet tall or more in a productive, indeterminate, vine-like habit and mature early in high-desert conditions. Flavor is sweet and pleasant when green, becoming richer with a distinctive bitter-sweet complexity as the fruit ripens red. It is the hottest of the northern New Mexico landraces, with Scoville Heat Units averaging 20,547 across multi-year trials (ranging 15,756–25,329 SHU), significantly higher than commercial types like Sandia. Culinary uses include roasting and stuffing while green, frying, or drying into flavorful powder and flakes when red. It thrives in full sun and well-drained soil at elevations around 5,500 feet, showing good adaptation to arid, high-desert environments.
