Canada Goldenrod

Solidago canadensis L.

The flowers of Canada Goldenrod are important nectar and pollen sources for insects, including bees, flies, wasps, and butterflies. Canada Goldenrod is incapable of pollinating itself, a task usually carried out by visiting insects. The plants and their seeds provide food for finches and other birds, and foraging animals (e.g. sheep, cattle, deer, horses). They have also been used by Indigenous people for medicinal and other purposes.

Physical Appearance:

The solitary, hairy stems of this perennial grow 30 to 214 cm tall. Its lance-shaped leaves have finely-toothed margins and hairy undersides.

The single-seeded fruits have a bristly top to aid in wind-dispersal.
