You know that summer will soon be over when the Goldenrod flowers appear. Goldenrod has clusters of bright yellow flowers (shaped like a spike or a pyramid) at the top of a tall stalk with long, narrow green leaves. The plant's height varies from a few inches to over 6 ft, but 2-3 ft is common.
Goldenrod grows across North America.
Did you know? Goldenrod doesn't cause hay fever as the pollen is slightly sticky and can't blow on the wind.
