Velvety Goldenrod
Solidago velutina
Aster family (Asteraceae)

Velvety Goldenrod is one of several Solidago species found in the region; there are about 80 species in North America. Goldenrods are often blamed for allergies but generally their pollen is too heavy to be readily wind-borne and it is other plants pollinating at the same time which people are allergic to.

"Solidago" is from the Latin "solidus" meaning "whole" or "solid," referring to the plant's supposed ability to heal. Linnaeus named this in 1753. "Goldenrod" is a common name applied to all Solidagos.
