Tepehuan Tomatillo is a frost-tender member of the nightshade family that thrives across hardiness zones 3 through 11, bringing the authentic flavor of Mexican cuisine to gardens across much of North America. This cultivar of Physalis philadelphica produces the characteristic green, paper-husked fruits that define traditional salsa verde, ripening to full flavor when left on the vine until the husk splits open. Starting seeds indoors at 68 to 86 degrees Fahrenheit gives you a head start in cooler regions, with plants ready to harvest once warm weather arrives and frost danger passes.

The Tepehuan Tomatillo delivers reliable harvests across a remarkably wide climate range, from cold-winter zones to subtropical gardens. Its frost-tender nature means you'll need to protect it from freezes, but the reward is abundant production of fruit that reaches peak flavor when the husk naturally splits. The moderate water needs make it manageable even during dry spells, and the neutral soil preference (pH 6.0 to 7.0) fits most garden beds without special amendment.
Tepehuan Tomatillo is grown for its edible fruits, which are the foundation of authentic Mexican salsa verde. The tart, slightly herbal flavor of the unripe green fruit is essential in this classic preparation, where the tomatillos are roasted, blended with cilantro, onion, and chiles to create the iconic sauce. The husked berries can also be used fresh in salsas, cooked down into preserves, or incorporated into various Latin American dishes where their tartness brightens rich or spiced elements.

Start seeds indoors 6 to 8 weeks before your last spring frost date. Sow seeds in sterile seed-starting mix and maintain soil temperature between 68 and 86 degrees Fahrenheit for reliable germination. Keep the soil consistently moist but not waterlogged. Seedlings will emerge in 7 to 14 days and should be grown under bright light to prevent legginess.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days once nighttime temperatures stay above 50 degrees Fahrenheit. Transplant after all danger of frost has passed and soil has warmed to at least 60 degrees Fahrenheit. Space plants 24 to 36 inches apart in rows or clusters, ensuring good air circulation around each plant.
Harvest Tepehuan Tomatillo fruits when the husk splits open and the fruit inside fills out completely, typically 60 to 80 days after transplanting. The ripe fruit will feel slightly soft to gentle pressure and the husk will have turned papery and begun to split naturally. You can twist or gently pull mature fruits from the vine. For salsa verde applications, many growers prefer the tart flavor of fully mature but still-green fruit rather than fully ripe specimens, so taste-test to find your preference. Continue harvesting throughout the season until frost threatens, then pick all remaining fruit regardless of maturity to preserve as much of the crop as possible.
