Wild rocket, Wild arugula arugola-diplotaxis-tenuifolia Wild rocket (Diplotaxis tenuifolia), often sold as arugula, is a perennial leafy brassica with narrow, deeply lobed leaves and a bold peppery flavor. Compared with cultivated arugula (Eruca sativa), it is usually slower from seed, more pungent, and more tolerant of heat and longer days. Plants form a hardy crown and a deeper root system, which supports repeated harvests over a long season. In mild climates it can overwinter reliably and start growing early in spring; in colder areas it may act as a short-lived perennial or need light protection. It also readily flowers if stressed, and the blossoms can be valuable for pollinators and beneficial insects. Growing conditions LightFull sun to partial shade. In hot summers, partial shade keeps leaves more tender. Soil typeWell-drained soil is key. Wild rocket tolerates leaner, sandier soils better than cultivated arugula, but performs best with some organic matter and good drainage. Water requirementModerate. Keep evenly moist during germination and establishment; once rooted it tolerates short dry spells, but consistent moisture gives faster regrowth and less tough leaves. Nutrient requirementLow to moderate. Too much nitrogen can give soft growth and stronger pest pressure; light feeding is usually enough. Back to plant list
