Showy Goldenrod

Solidago nemoralis Ait.

Showy Goldenrod is abundant and widespread on the Canadian prairies. It is an important plant because it provides nectar and pollen to a wide range of insects. This species is common on dry, sandy soils. Contrary to popular belief, Goldenrod does not cause hay fever because its pollen is not wind dispersed.
