Wild arugula consists of small, jagged leaves, averaging 7 to 20 centimeters in length, that grow in bunches surrounding slender, upright stalks with bright yellow flowers. The leaves are elongated, dark green, narrow, and deeply lobed with lightly serrated edges. The surface also bears prominent veining that connects into the central, pale green stem. Wild arugula has a crisp consistency with an intense, pungent flavor containing sweet and bitter notes of pepper, nuts, horseradish, and pine. It is important to note that the sharp, zingy taste of Wild arugula is more robust than common arugula and should be used sparingly in culinary dishes.
