Overview

Solidago is a very large genus of perennial, herbaceous, flowering plants called goldenrods. It has a worldwide distribution, occuring on every continent except Antarctica. There are about 100 species of goldenrod worldwide, at least 77 in North America north of Mexico, and 16 in Minnesota. Most are native to North America, 8 are native in Mexico, 4 in South America, and 6 to 10 in Europe and Asia. Most are found in prairies and other open areas, a few are woodland species.

Goldenrods have an undeserved reputation for causing hay fever because they are showy and grow in the same locations and in close proximity to ragweeds.

Description

Goldenrods have composite flower heads with short ray florets and short disk florets. Most rise from underground creeping stems; have leafy, erect or ascending stems; and have yellow corollas.
