Tomatillo
Physalis philadelphica
Overview
The tangy, citrusy fruit inside a papery husk that is the essential ingredient in Mexican green salsa (salsa verde). Tomatillos are related to tomatoes but have a distinctly sharp, bright flavor that is completely their own. They are easier to grow than tomatoes, less susceptible to disease, and incredibly productive — but they need at least two plants for cross-pollination.
Growing Conditions
How to Grow Tomatillo
Tomatillo (Physalis philadelphica) is a forb/herb that grows to about 3 feet tall and 2 feet wide.
To grow tomatillo, give it full sun. It is hardy across USDA hardiness zones 4–11. Plant it in well-drained, moderately fertile, warm soil, at a slightly acidic pH of 5.5–7. It does best with even, moderate watering.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Its flowers appear from June through October, offering high value to pollinators. Let a few flowers go by unpicked; the bees will thank you, and so will next season.
Companion Planting & Soil
Tomatillo grows well alongside basil, parsley, carrot, marigold, and nasturtium — but keep it clear of fennel, dill, and walnut.

Uses
In the Kitchen
In the kitchen, tomatillo turns up in more than one form: essential for salsa verde and green enchilada sauce; roasted with peppers for smoky salsas; added to soups, stews, and pozole.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: rich in withanolides with anti-inflammatory properties; good source of vitamins C and K; contains niacin and potassium. These are traditional uses, not medical advice.
Beyond the Garden
Tomatillo earns its keep past the plate, too: easier to grow and more disease-resistant than tomatoes; self-seeding annual that returns in mild climates.
Safety Notes
Unripe fruit and the papery husk should not be eaten. All parts except ripe fruit are toxic (nightshade family).
