Helenium is a genus of annuals and herbaceous perennial plants in the family Asteraceae, native to the Americas.

A number of these species (particularly Helenium autumnale) have the common name sneezeweed, based on the former use of their dried leaves in making snuff.

Genus level properties: most conspicuously globe-like disk-shaped flowers, rays three-lobed at tip.

Annual species are easily grown from seed, and perennials should be divided every year in order to retain their vigor.
