plant sale text: Unlike its goldenrod relatives with yellow flowers, this unusual goldenrod species has white flowers! White prairie-goldenrod is native to dry, rocky woodlands and prairies across central and eastern North America. Its abundant white daisy-like flowers bloom in late summer into fall on top of sturdy upright stems with narrow, willow-like leaves. This species is extremely hardy and tolerant of drought and poor soils, and it thrives in average to dry, well-drained sandy or rocky soils in full sun. It is a unique addition to the fall garden and combines well with asters and other late-blooming perennials.
