Arugula is grown as a leaf vegetable for its fresh, peppery flavor. Other names include garden rocket, eruca, rocket salad, rucola, rucoli, rugula, and roquette. Indigenous to the Mediterranean region, it has been used as an important salad plant for centuries.
Thriving in cool weather, it can thrive in warm climates with some shade protection. It is equally happy in the garden or a container.
