A perennial low-growing, creeping plant, woodsorrel grows in both full sun and shade if there is adequate moisture. Roots form along its stem where nodes contact the soil. Leaves are three heart-shaped leaflets and range from green to purple. Flowers have 5 yellow petals, each about 1/3 inch long on the ends of slender flower stalks. Seed pods are erect, hairy and cylindrical, 1/3 to 1 inch long. Each pod has 10 to 50 seeds, with more than 5000 seeds per plant. Plants can produce seed even when kept mowed to 1/4 inch.
