The culinary leek, A. porrum L., is a horticultural derivative of A. ampeloprasum. It differs in its more cylindric bulb, stouter stem, broader leaves, milder odour and taste, and its biennial life-cycle. It is frequently grown in domestic and commercial gardens and may persist shortly in and around these areas.
