Goldenrod is one of the last flowers to bloom in the season and are therefore an important food source for pollinators and birds as we go into winter. This plant is named for its bright golden flowers that form in clusters at the top of the plant. Goldenrod spreads aggressively by rhizome so it may not be appropriate for a small perennial garden.
Goldenrod often is blamed for late season allergies. This is not true as their pollen can not become airborne as it is quite large and sticky. Instead ragweed and mold are usually the allergen culprits. In fact, the flowers of goldenrod can be used in a tincture to help allergies by reducing inflammation.
