Helenium autumnale (Common sneezeweed)
Helenium autumnale, often called common sneezeweed or autumn sneezeweed, is a species that turns stream banks and marsh edges into a sea of golden yellow when in bloom late summer into fall. The flowers have a distinctive button-like appearance, with notable round golden colored disks.
Despite its name, the plant does not trigger sneezing; the name comes from the historical use of its dried leaves in powdered snuff to induce sneezing. This plant thrives in consistently moist soils and can grow 3 to 5 feet tall, forming dense, upright clumps that add structure and late-season color to wetland edges, rain gardens, and moist pollinator gardens. Because of its upright habit and long blooming period, it is also suitable for cut flower use and for adding vertical interest to native garden beds.
Ecologically, Helenium support a wide variety of native pollinators, including bees, butterflies, and syrphid flies. It is especially valuable for providing nectar and pollen during the late season, when fewer native plants are in bloom. Additionally, Helenium support several specialist bees.
Deer and rabbits tend to avoid Helenium, making it a resilient option in landscapes with browsing pressure.
