Plant Description
Sneezeweed is an erect, upright, clump-forming, fibrous-rooted, perennial wildflower with stout green winged stems and shallow fibrous roots. The plant normally grows about 2 to 5 feet in height and 2 to 3 feet in width. The plant is found growing in wet meadows, marshes, rich thickets, meadows, shores, moist calcareous soils, wet openings, edges, along rivers, streams and ponds, mesic hardwoods floodplains, sandy alluvial dikes, drainage ditches, pine flat wood depressions, wet woodlands, wet roadsides, moist soil of limestone bluffs, moist black land prairies, fens, forests, seepage areas, soil prairies, railroads, poorly drained pastures and abandoned fields. The plant prefers loamy or silty soils that are high in organic matter. Plants can thrive in wet or evenly moist soil but will tolerate a bit of drought after establishment.
Stem
Stems are erect or ascending, winged, and branched above the middle. Above the middle the stems are moderately to densely covered with short, spreading to ascending, somewhat curled hairs. They are also moderately covered with yellow, stalk less or impressed glands. Below the middle the stem is sparsely to moderately hairy.
Leaves
Stem leaves are alternate, stalk less, numerous, and spread outward. The leaves are longest at the middle of the stem, becoming slightly smaller as they ascend the stem. The upper and lower surfaces are sometimes hairless but are usually moderately to densely covered with short, mostly spreading, sometimes curved hairs. They are also densely dotted with yellow, stalk less or impressed glands. Middle and upper stem leaves are 1½ inches to 6 inches long and 3 ⁄16 inches to 2 inches wide. Basal and lower leaves are somewhat smaller than middle stem leaves. Basal leaves are lance-shaped, inversely lance-shaped, or inversely egg-shaped, and are sometimes cut with shallow, rounded lobes (pinnatifid). Lower and middle stem leaves are inversely egg-shaped to inversely lance-shaped. They are tapered at the base and angled or taper to a sharp point at the tip. The base of the leaf blade continues down the stem as a narrow, green wing. The margins are either untoothed or are toothed often only above the middle of the blade. Upper stem leaves are inversely lance-shaped to lance-shaped but otherwise similar to middle stem leaves. Basal and lower stem leaves are absent or withered by flowering time.
Flower
The inflorescence is 2 to 25 flower heads in open, leafy, branched, panicle-like clusters at the end of the stems and branches. Each cluster is on a ¾ inches to 3 inches long, sparsely to moderately hairy stalk. The whorl of 15 to 21 green bracts at the base of the flower head (involucre) is globe-shaped, 5 ⁄16 inches to ⅝ inches long, and ⅜ inches to ⅝ inches in diameter. The bracts of the involucre (phyllaries) are in 2 series. The outer phyllaries are fused at the base.
Each flower head is 1 inch to 2½ inches in diameter. There are 8 to 21 ray florets and 200 to 400 or more disk florets. The ray florets are yellow, ⅜ inches to 1 inch long and ⅛ inches to ⅜ inches wide and double notched at the tip. They are narrow at the base and taper evenly to a broad tip. The disk florets are yellow to brownish and form a large, globe-shaped, sometimes somewhat flattened disk. Flower stalks are finely hairy and slightly swollen at the base of the flower. Flowers appear over a lengthy late summer to autumn (sometimes to first frost) bloom as indicated by species name. Flowering normally takes place in between August to October.
Fruit
Fertile flowers are followed by dry, one-seeded, 1 ⁄16 inches long seed capsule (cypsela) with a tuft of 5 to 7 short bristles (pappus) attached to the end. Seeds are finely hairy but lack a tuft of hairs at the tip.

Other Facts
- The chemicals in sneezeweed can poison livestock, particularly sheep.
- The sesquiterpene lactone helenalin found in sneezeweed has insecticidal properties and has been found to be poisonous to fish and dogs.
- The plant is toxic to livestock.
- Helenium means tenderness and tears.

- The plant is poisonous to ruminants.
- Contact with the plant might cause dermatitis in sensitive people.
- It may cause sneezing and skin rash.
