Plant notes
This plant produced many clusters of small golden flowers. Plants filled in well and flowered throughout September. In addition to beneficial insects, many insects were seen at this plant, including locust borer. This was the fifth most attractive late season plant to natural enemies, with four times as many natural enemies as the grass control.
Habitat
This plant grows in full sun to partial sun, and fairly dry to very wet locations. It is naturally occurring in wet prairies, fens, shore meadows, and on low ground along rivers and around lakes.
Cultivation and management
This goldenrod can be grown from seed (It flowers in the second or third year.) or plug material (flowers in first or second year). We saw no evidence of deer or other vertebrate browsing on this species.
