Arugula
Eruca vesicaria subsp. sativa
Overview
A peppery, fast-growing salad green that has been cultivated since Roman times as both food and aphrodisiac. Arugula's distinctive mustardy bite comes from glucosinolates, the same cancer-fighting compounds found in broccoli. It bolts quickly in heat but thrives as a cool-season crop and readily self-seeds for continuous harvests.
Growing Conditions
How to Grow Arugula
Arugula (Eruca vesicaria subsp. sativa) is an annual forb/herb that grows to about 12 inches tall and 8 inches wide.
To grow arugula, give it full sun, though it tolerates a little shade. It is hardy across USDA hardiness zones 3–11. Plant it in moist, fertile, well-drained soil, at a slightly acidic pH of 6–7. 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 May through August, offering moderate value to pollinators. An annual gives everything in a single season; enjoy it while it lasts.
Companion Planting & Soil
Arugula grows well alongside carrot, beet, onion, dill, and lettuce — but keep it clear of strawberry.

Uses
In the Kitchen
In the kitchen, arugula turns up in more than one form: fresh in salads, sandwiches, and as pizza topping; blended into pesto as an alternative to basil; wilted into pasta and grain bowls.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: rich in glucosinolates with anti-cancer properties; high in vitamin K for bone health; contains nitrates that support cardiovascular function. These are traditional uses, not medical advice.
Beyond the Garden
Arugula earns its keep past the plate, too: quick-growing catch crop between slower vegetables; flowers attract beneficial pollinators.
