Arugula Vegetable

Eruca sativa (syn. E. vesicaria subsp. sativa (Miller) Thell., Brassica eruca L.) is an edible annual plant, commonly known as salad rocket, roquette,rucola, rugula, colewort, or, in the United States, arugula. Salad rocket (arugula) is sometimes conflated with Diplotaxis tenuifolia, the perennial wall rocket, another plant of the Brassicaceae family, which in the past was used in the same manner. Salad rocket is a species of Eruca native to the Mediterranean region, from Morocco and Portugal in the west to Lebanon and Turkey in the east. Eruca sativa differs from E. vesicaria in having early deciduous sepals. Some botanists consider it a subspecies of Eruca vesicaria: E. vesicaria subsp. sativa. Still others do not differentiate between the two. The Latin adjective sativa in the plant's binomial is derived from satum, the supine of the verb sero, meaning "to sow", indicating that the seeds of the plant were sown in gardens.
Arugula typically grows on dry, disturbed ground and is also used as a food by the larvae of some moth species, including the Garden Carpet moth. Arugula roots are also susceptible to nematode infestation.
