Eupatorieae is a tribe of over 2000 species of plants in the aster family. Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere. Well-known members are Stevia rebaudiana, a number of medicinal plants (Eupatorium), and a variety of late summer to autumn blooming garden flowers, including Ageratum (flossflower), Conoclinium (mistflower), and Liatris.
Heterotheca, are North American plants in the sunflower family.
Eurybia spinulosa, commonly called the Apalachicola aster or pinewoods aster, is a perennial herb in the composite family.

Conoclinium coelestinum, the blue mistflower, is a North American species of herbaceous perennial flowering plant in the sunflower family. It was formerly classified in the genus Eupatorium, but phylogenetic analyses in the late 20th century research indicated that that genus should be split, and the species was reclassified in Conoclinium.
Bidens aurea is a North American species of flowering plant in the daisy family. It is widespread across much of Mexico and found also in Arizona and Guatemala. The species is also naturalized in parts of Europe and South America.
