The native Wild Lettuce is common in our area. It prefers full or partial sun and moist to slightly moist conditions. Habitats include black soil prairies, openings in woodlands, savannas, pastures and neglected areas. This biennial is usually unbranched and 3-8' tall. The alternate leaves are up to 10" long and 3" across. The largest leaves have deep pinnate lobes. The small dandelion-like flowers occur in a narrow panicle up to 2' long at the apex of the plant. Each flower is about 1/2" across, consisting of 12-25 ray florets that are yellow or slightly reddish orange (and no disk florets).
