Alcalde Pepper is an early-maturing chile cultivar from the high deserts of Rio Arriba County in northern New Mexico, originally collected in 1999 and now part of Native Seeds/SEARCH's Seed Bank Collection. This half-hardy annual produces 4-inch peppers with a mild-to-medium heat level and a complex, slightly sweet flavor when allowed to mature to red, though the green stage offers a different culinary experience. It thrives in moderate watering conditions and prefers soil with a pH between 6.0 and 6.8, reaching its full potential in warm climates where it can germinate at temperatures between 70 and 85 degrees Fahrenheit.

Born from the high-altitude deserts of northern New Mexico at 6,300 feet elevation, Alcalde Pepper carries the resilience of its native landscape into home gardens. The mild-to-medium heat paired with a subtly sweet undertone creates a flavor profile that works equally well in fresh preparations and cooked dishes. Its early maturity means you'll be harvesting peppers well before the first frost, and the ability to harvest at either the green or fully red stage gives you flexibility in the kitchen and extends your picking window throughout the season.
Alcalde Peppers can be harvested and used at two distinct stages, each with its own culinary character. The green peppers offer a fresh, bright option for roasting, chopping into salsas, or adding to stir-fries and cooked dishes. When left to mature to red, they develop a more complex, slightly sweet flavor that works beautifully in slow-cooked sauces, dried chile preparations, or eaten fresh off the plant. Their mild-to-medium heat makes them approachable for a range of palates while still delivering genuine chile flavor.

Start seeds indoors 6 to 8 weeks before your last spring frost date in warm soil maintained at 70 to 85 degrees Fahrenheit. Keep soil consistently moist but not waterlogged, and provide bright light once seedlings emerge.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days. Transplant outdoors once nighttime temperatures consistently remain above 50 degrees Fahrenheit and space plants 18 inches apart in rows 24 inches apart.
Alcalde Peppers can be harvested at two stages depending on your preference. Pick peppers when they reach 4 inches in length and are still green for a fresh, slightly brighter flavor, or leave them on the plant to mature to red for a more complex, mildly sweet character. Use a clean knife or pruners to harvest, cutting the stem rather than pulling, which can damage the plant. Continue harvesting throughout the growing season to encourage the plant to produce more flowers and fruit.
