Arugula is an annual, small, fast-growing plant belonging to the Brassicaceae family and is popular for its edible leaves, which have a slightly spicy taste. Although the plant originates from the Mediterranean, today, it is common in most countries of the world, where it is used to prepare many dishes, including salads and soups.
Eruca vesicaria is easily identified by its oblong, dark green-toothed leaves that grow on slender stems that can grow up to 23 in (60 cm) tall. The flowers bloom in summer, are yellow-white with purple lines, and are up to 4 cm (1.6 inches) in size. The fruits are small pods up to 1.2 in (3 cm) long, with a somewhat flattened shape and edible seeds arranged in several rows, which are also used in cooking.
