It is biennial or periennial, and spreads primarily by seed.[3] It grows from 1 to 4.5 feet tall, and is found in mesic deciduous woodlands.[3] The whitish-green flowers with sepals longer than petals, appearing late spring or early summer and lasting for approximately three weeks, are green and bur-like.[3][4] The bur-like fruit each split into 2 seeds.[3][4] The species ranges throughout the eastern United States (excluding Maine), extending north into Quebec and Ontario, and west into Texas and Wyoming.
