Growing notes
- Exceptional late-season bee forage — a critical autumn nectar source as other meadow plants finish
- Larval host plant for numerous specialist insect species
- Does NOT cause hay fever — the culprit at goldenrod’s flowering time is wind-pollinated ragweed (Ambrosia) flowering at the same time, goldenrod pollen is heavy and insect-carried
