Solidago bicolor (white goldenrod)

White goldenrod is a wildflower in the aster family that flowers from late summer into the fall with a distinctive combination of white and yellow flowers. It has elongated spikes of short-stalked flower heads with white to yellowish-white rays surrounding a yellow central disk atop a hairy, grayish stem. This plant is the only goldenrod in the eastern United States with white ray flowers. Does well in full sun or partial shade and adapts to clay, loam, sandy or shallow rocky soils. Prefers good drainage. Extremely tolerant of dry soil. Generally low-maintenance once established. Grows to 1–3' tall.

Produces nectar that attracts butterflies, native bees, honey bees, and other pollinators. Songbirds eat the seeds. Members of the Solidago genus support a variety of specialized bees. This plant is a host plant for wavy-lined emerald moth  larvae.
