"Helianthus divaricatus", commonly known as the woodland sunflower, is a perennial herb in the composite family. It is native to eastern North America, from Ontario and Quebec in the north, south to Florida and west to Oklahoma and Iowa. It commonly occurs in dry, relatively open sites. The woodland aster is similar to "Helianthus hirsutus", but the former has hairless stems that are often glaucous, sessile leaves (i.e. they lack a leaf stalk), and smaller reproductive organs. The showy yellow flowers emerge in summer through early fall.Citation
