Diplotaxis tenuifolia is a species of flowering plant in the mustard family known by the common name perennial wall-rocket. This plant is native to Europe and Western Asia. It can be found throughout much of the temperate world where it has naturalized.
This is an erect mustard-like plant with branching stems that may exceed half a meter in height. It grows in clumps on the ground in a variety of habitats and is a common weed of roadsides and disturbed areas. It has long leaves which may be lobed or not. The foliage is aromatic when crushed. Atop the branches of the stem are bright yellow flowers with four rounded petals each about a centimeter long. The fruit is a straight, flat silique up to five centimeters long.
Perennial wall rocket, wild rocket, sand rocket, Lincoln weed, white rocket; seeds sometimes marketed as "wild Italian arugula" or "sylvetta arugula".
Baby leaf rocket is cultivated worldwide as a salad leaf. There are two species which are commercially cultivated an annual (Eruca sativa Mill.) and a perennial (Diplotaxis tenuifolia (L.) DC.). These leaves are usually mixed with other baby leaf crops to form a mesclum style salad. These crops have become popular due to their distinctive taste and texture in salads. Popularity of baby leaf crops has increased greatly in recent years as they are perceived as being convenient and nutritious.
