Parsley-piert is a small and inconspicuous annual plant. The stem is sometimes prostrate, but usually erect, and much branched from the base. It is rarely more than 4 inches high. The leaves are of a dusky green color and wedge-shaped with deeply cut lobes. The whole leaf is less than 1/2 inch wide, narrowed into a short foot-stalk with leafy stipules, sheathing and cleaving to the footstalk. Slender, scattered hairs cover the entire plant. The pale green, small and stalkless flowers are crowded together in tufts. The plant is in bloom from May to August.
