(Helenium autumnale)

Species Description
Description:
Despite its unfortunate name, Common Sneezeweed is a stunning late-season perennial that brightens the landscape with a profusion of daisy-like flowers. Its most iconic feature is its wedge-shaped, yellow petals that are notched at the tips, surrounding a prominent, spherical center disk that looks like a golden pincushion.
Habitat in the ANF
In the Allegheny National Forest, this is a plant of wet, sunny edges. You will rarely find it in the deep shade of the woods; instead, look for it in moist meadows, along the marshy banks of the Allegheny River, and in the "wet ditches" along forest roads. It thrives in soils that stay damp throughout the summer, often standing tall amongst late-blooming asters and goldenrods.
Ecology and the Misunderstood Name
The name "Sneezeweed" is actually a historical misunderstanding. It does not cause hay fever—its pollen is heavy and sticky, designed to be carried by bees rather than the wind (the true culprit for sneezing is usually the inconspicuous Ragweed). The name comes from the traditional practice of drying and grinding the flower heads into a snuff used to induce sneezing, which was believed to rid the body of "evil spirits" or clear the nasal passages during a cold.
Identification
The Petals: Look for the "toothed" tips. Each bright yellow petal (ray floret) is narrow at the base and wide at the end, typically with three distinct teeth at the outer edge.
The "Winged" Stem: A key identifying feature is the stem. Unlike most sunflowers, the leaves of the Sneezeweed actually extend down the stem to form leafy "wings" or ridges that run vertically along the stalk.
The Center: The central disk is nearly spherical and stays yellow or yellowish-green for a long time, eventually turning a darker gold as the season progresses.
The Height: This is a tall, sturdy plant, often reaching 3 to 5 feet, with branching tops that hold dozens of flower heads.
