Solidago canadensis L.
Canada Goldenrod, Canadian Goldenrod, Tall Goldenrod, Giant Goldenrod
Asteraceae (Aster Family)
USDA Symbol: SOCA6
Tall, leafy, finely hairy stem has tiny yellow flower heads on arching branches in a long or flat-topped cluster at top.
This handsome species produces showy displays, usually late in the summer. Although it and other Goldenrods are commonly blamed for hay fever, this discomfort is usually caused by pollen from Ragweed (Ambrosia spp.), which are less conspicuous plants with greenish flowers that bloom at the same time. Missouri Goldenrod (Solidago missouriensis) is similar but usually smaller, with smooth stems.
