Goldenrods are keystone species in our region and offer excellent late-season forage for pollinators as well as being host plants for many insect larvae*. There are many different forms of goldenrods that can grow in various conditions. To know them is to love them.

Goldenrods have gotten bad publicity for causing allergies, however, they do not. The wind-pollinated ragweeds (Ambrosia species) that bloom at the same time, but are much less showy, are the cause of hay fever. Goldenrod pollen is large and sticky in order to adhere to visiting insects and therefore cannot become airborne.

*Here is a very general list of the insects that utilize our beautiful goldenrods: Butterflies, Moths, Beetles, Carpenter bees, Sweat bees, Plasterer bees, (The North Carolina Extension Gardeners Plant Toolbox has an extensive list of Goldenrod-supported specialized bees. Check it out!), Sphecid wasps, Vespid wasps, Tachnid flies, Flesh flies, Blow flies, Muscid flies, the Gall-formers such as Epiblema scudderiana, Asteromyia carbonifera, Gnorimoschema gallae solidaginis, and Procecidochares atra, all of which are native to Maine (such an interesting group - look for the galls in the late fall and early winter when they are easy to spot on the dried up stems).
