Description
Diplotaxis tenuifolia, commonly known as wild rocket, is a perennial herb with narrow, deeply serrated leaves and a sharper, more peppery flavor than the annual garden rocket. It forms dense clumps over several years and reliably regrows after cutting, making it a productive perennial for small gardens or balcony pots. Small yellow cross-shaped flowers appear from early summer to autumn, attracting wild bees. Young leaves are harvested continuously; older foliage becomes increasingly sharp and is better suited for seasoning than fresh salad.
Care instructions
Wild rocket prefers a sunny to partially shaded spot with well-draining, somewhat lean soil. Water moderately and allow the soil to dry slightly between waterings; excess moisture harms the roots more than brief dryness. Regularly trim the outer leaves a few centimeters above the soil to encourage new growth and keep the plant compact. Remove flower stems early if milder leaves are desired; otherwise the flavor will become noticeably sharper over time. As a perennial, it tolerates mild winters outdoors and regrows from the roots each spring.
