A European "weed," common everywhere. In California it grows to an enormous height, sometimes twelve feet, and when in bloom is a beautiful feature of the landscape, covering the fields with a shimmering sheet of pale gold. The leaves are dark-green, smooth or with a few hairs, all with leaf-stalks, the lower leaves large and jagged, cut into leaflets, the upper leaves mostly toothless. The fragrant flowers form long clusters, each flower about three-quarters of an inch across; the small, cylindrical pods stand erect, close to the branching stem. A valuable, antiseptic oil is made from the black, pungent seeds, exported from California by the ton.
