Variety History

Rocket (Eruca sativa) has been cultivated since Roman times — it appears in Virgil and Pliny. It was traditionally used as both a salad green and an aphrodisiac. The name "rocket" comes from the Latin "eruca."

Regional Context

Arugula is a PNW rockstar in spring and fall. Our cool weather produces mild, tender leaves. Direct sow as soon as soil can be worked (February with row cover). Two main windows: March-May and September-November. It self-sows enthusiastically — once you grow arugula, you will always have arugula.

Growing Technique

Direct sow in early spring (March) and again in late summer (September). Arugula germinates in cool soil and grows fast — 21 days for baby greens, 40 days for mature. Sow 1/4" deep, scatter seeds (9-16 per sq ft). Keep moist — drought stress makes leaves intensely peppery. Harvest by cutting outer leaves or whole rosettes. Arugula bolts quickly in heat and long days — spring plantings are done by late May. Fall plantings overwinter under row cover. Succession sow every 2-3 weeks for continuous harvest. The flowers are edible too — peppery-sweet, beautiful on salads.

Watch For

  • Bolting is the main issue — once day length exceeds 14 hours, arugula triggers flowering. Plant in partial shade to extend the spring season. Flea beetles love arugula — floating row cover or accept tiny holes. Slugs also love it — bait at planting. Over-mature leaves become tough and overwhelmingly spicy.
