Helenium autumnale is a North American species of poisonous[3] flowering plants in the family Asteraceae.

In late summer and fall, one plant can produce as many as 100 yellow flower heads in a branching array.

[9] This plant is widespread across much of the United States and Canada, from Northwest Territories as far south as far northern California, Arizona, Louisiana, and Florida.

The dried nearly mature flower heads are used in a powdered form as a snuff to treat colds and headaches.

[1] The plant owes its name to the use of its dried leaves in snuff, the inhaling of which causes sneezing—supposedly casting out evil spirits.
