The native Tall Beggar's Ticks is uncommon in our area. It prefers full sun to light shade, moist conditions and soil with sufficient organic material to retain moisture. Habitats include openings in moist woodlands, woodland borders, thickets and meadows in floodplain areas, marshes and seasonal wetlands. This annual is 2-3½' tall, branching occasionally in the upper half. The compound leaves are usually odd-pinnate, consisting of 3 or 5 leaflets. The leaflets are up to 3" long and 1" across, lance-shaped, coarsely toothed, with rather long and pointed tips. Some of the upper stems terminate in individual flowers ¾–1" across on long stalks; some stalks may have 1-2 additional flowers smaller in size. The flowers have numerous disk florets that have dull yellow corollas with bases surrounded by 11-20 green leafy bracts. The brown seed heads have 2-pronged burs with tiny barbs pointing downward.
