plant sale text: In late summer, Woodland Sunflower produces two-inch flowers borne on upright slender stems. Yellow rays surround a slightly darker yellow central disk. Its handsome green leaves have a sandpaper-like texture. This species is found in open rocky woods and along roadsides. It is quite drought-tolerant, once the plant's root system has gotten established. Over time, this species spreads with creeping rhizomes to form colonies. The seeds of this handsome native sunflower are a great food source for birds.
