Upland White GoldenrodSolidago ptarmicoides (Torr. & A. Gray) B. Boivin
This prairie perennial is actually a Goldenrod even though its flowers are white not yellow. It has numerous, small, white daisy-like flowers that attract butterflies, flies, bees, and beetles – many of which are also pollinators. It prefers drier, sandy soils, and is drought tolerant.
