Very few annuals have as many varying growth habits as lambsquarters. Along roadsides it may reach a sprawling three or four feet in height, while in lawns seed production starts at only a few inches. Leaves are wide at the base, irregularly toothed along the margins and taper to a blunt or rounded tip. On the upper branches, they are long and narrow. Seeds are formed in spike-like clusters at the top of the plant and in the axils of the leaves. The most distinctive characteristic of lambsquarters is the white, mealy appearance of the pale green leaves.
