Description from Prairie Moon Nursery: The large and numerous daisy-like, yellow flowers of Helenium autumnale can provide welcome color in late summer and autumn when many other blossoms have disappeared. Sneezeweed prefers full to partial sun and wet to wet-medium soils. Despite its common name, it presents no problems for most allergy sufferers. Its pollen is distributed by insects, not wind. Sneezeweed is one of the host plants of the Dainty Sulphur.
*Sneezeweed does not derive its common name from the effects of its pollen. It was crushed to make a snuff that promoted sneezing. (Ontario Native Plants 2002)
