Nothing heralds the coming Autumn for me like the very beautiful and showy yellow flowers of Goldenrod (Solidago canadensis, Solidago spp.). Although, Goldenrod, in all her golden glory, is the scapegoat for fall allergies, it is actually the common Ragweed (Ambrosia artemisifolia) with its inconspicuous green inflorescence also blooming at this time that is usually to blame. Goldenrod has very little pollen and what pollen it does have is very dense and sticky in order to be carried off by insects that visit. Ragweed on the other hand, makes a profusion of pollen that is distributed on the wind. Solidago canadensis is a Native perennial that spreads rapidly through its rhizomes. Often found in dense stands, there are approximately 60 species of Goldenrod in the Northern Hemisphere found in all states except Hawaii, Louisiana, Georgia, South Carolina, and Florida. Goldenrod is also found in nearly all of the Canadian provinces. Goldenrod is found in moist meadows, near waterways, and prairies in locations with full or part sun. It ranges in height from 1 to 7 feet with bright flowers arranged in drooping panicles.
