Often overlooked and misunderstood, goldenrods play an invaluable role in our local ecosystems. These golden-yellow perennials are ecological powerhouses that deserve a prominent place in our gardens and landscapes. With 22 different species of goldenrod (Solidago) native to Michigan alone, it's time to shed misconceptions and embrace this keystone species for the biodiversity hero it is.
Goldenrod is a critical component of local ecosystems in Ann Arbor and beyond. Solidago species support at least 135 species of caterpillars and hundreds of pollinators, providing essential food sources for a variety of insects. These insects, in turn, are critical food sources for native birds and other wildlife species.
One of the most pervasive misconceptions about goldenrod is its alleged role in causing seasonal allergies. While it's true that goldenrod blooms coincide with allergy season, it is not the source of hay fever misery. The real culprit is ragweed, which releases lightweight pollen that easily becomes airborne and causes allergic reactions. Goldenrod pollen is heavy and sticky, making it unlikely to be an airborne allergen.
Goldenrods are among the hardiest native wildflowers in North America, making them an excellent choice for gardeners of all skill levels. The rich diversity of native goldenrod species in Michigan ensures there is a goldenrod for every growing condition from shade to sun and wet to dry soil. Their stunning yellow flowers bloom in late summer to fall, providing a much-needed splash of color during a period when many other plants have finished their blooming cycles. This extended blooming period also ensures a continuous supply of nectar and pollen for late-season pollinators. Even in fall and winter goldenrods provide for wildlife, with many songbirds eating the showy seedheads.
Next time you consider adding new plants to your garden, remember goldenrod. This often-misunderstood wildflower is not a weed but a valuable ally in promoting biodiversity and sustaining wildlife.
For those interested in adding this plant to your gardens, we will have several species of Goldenrod available at our Native Plant Sale on August 17 and 18th at Matthaei Botanical Gardens.
