Landscape: a strong standing, adaptable plant that provides bright yellow flowers for the fall season. It is an important source of nectar for butterflies and bees in autumn.
Comments: Synonym for stiff goldenrod is Oligoneuron rigidum. William Ellery Channing poetically wrote,
"I see golden-rod shine bright, as sun-showers at the birth of day,
A golden plume of yellow light, that robs the day-god's splendid ray"
Etymology: The epithet name rigidum is Latin for "rigid" because of the stiff nature of the plant. The genus, solidago, comes from the Latin word, solida meaning "whole" and ago meaning "to make".
