Baby arugula refers to the young, tender leaves of arugula (Eruca vesicaria). Some varieties and salad mixes also include baby wild arugula (Diplotaxis tenuifolia), a closely related species with narrower, more deeply lobed leaves and a more robust peppery flavor. Both belong to the Brassicaceae (cruciferous) family and provide many of the same health-promoting compounds, including glucosinolates, vitamin K1, folate, lutein, and naturally occurring nitrate.

Baby arugula has a delicate texture and mild peppery flavor, while baby wild arugula offers a more robust, spicy, and slightly bitter taste. Either variety—or a blend of both—adds freshness and complexity to salads, sandwiches, wraps, grain bowls, pizzas, pasta dishes, and pesto.
