Swamp Sunflower. Golden daisy-like blooms open on this native wildflower in fall and linger until frost. Swamp sunflower blooms best in full sun but can grow in part shade, although plants will be lanky. This perennial grows 36 to 72 inches tall and wide and thrives in moist soil but can survive in well-drained soil, provided you water occasionally. Plants are hardy in Zones 6 to 9, but readily seen to Zone 3.
