Description

Solidago bicolor, or White Goldenrod, is a herbaceous perennial wildlflower in the Asteraceae family. It flowers in late summer into the fall and displays an elongated spike of short-stalked flower heads with white to yellowish-white rays surrounding a yellow central disk atop a hairy, grayish stem. This is the only species of Solidago with white rays found on the east coast.

White Goldenrod grows well in dry, often poor, soil, in full sun to partial shade, and seems to prefer soil with a heavy clay content. It tolerates drought. Goldenrod species are sometimes blamed for hay fever, but the irritating pollen is actually a product of ragweed (Ambrosia species), whose pollen is airborn when goldenrod is in flower.

The White Goldenrod flowers produce nectar that attracts butterflies, native bees, honey bees and other pollinators. Songbirds eat the seeds.  Members of the genus Solidago support the following specialized bees: Andrena (Callandrena s.l.) asterisAndrena (Callandrena s.l.) braccataAndrena (Cnemidandrena) hirticinctaAndrena (Cnemidandrena) nubeculaAndrena (Callandrena s.l.) simplexPerdita (Perdita) octomaculataMelissodes (Eumelissodes) fumosusColletes simulansand Colletes solidaginis.

Because this genus includes up to 120 species, most of which display small yellow flowers, this plant can be confused with others of its genus Solidago spp.
