Deeply lobed and coarsely toothed towards the base of the plant, up to 12 inches long and to 6 inches wide, gradually becoming smaller, smooth-edged and unlobed at the top. No leaf stem at the stalk. Leaves taper to points at both ends and the edges are somewhat wavy.
Notes:The unusual leaves of this plant make it pretty easy to identify even when it isn't in bloom. Also, nearly all references I've come across say the flowers of Wild Lettuce are yellow, but the plants that I found had distinctly pink petals, though they turned yellow towards the center.
