What does sneezeweed mean?
Sneezeweed is a North American common name for flowering perennials in the genus Helenium, most famously Helenium autumnale, a tall plant bearing yellow, daisy-like flowers in late summer and autumn. The name preserves an unusual historical use: dried plant material was made into an inhalable powder or snuff that provoked sneezing. Although garden references often use the name specifically for Helenium autumnale, it can apply more broadly to related species. In present-day writing, sneezeweed is chiefly encountered in botanical descriptions, native-plant gardening, and discussions of traditional uses. Its name may initially sound like a reference to garden weeds or to a plant associated with allergies, but it does not ordinarily describe a weed or imply that merely touching the plant causes sneezing. The word is therefore both a useful botanical label and a reminder of how common names often preserve obsolete everyday practices.

Sneezeweed was once used as sneezing powder—so its name was practically a piece of advice.
