Erigeron vernus is a North American species of flowering plant in the family Asteraceae known by the common name early white-top fleabane. [3] It is native to the southeastern United States from Virginia to Louisiana. [4] It is found most commonly in habitat types such as interdunal swales, wet savannas, cypress swamps, among others. [5] It acts as an indicator species in the savannas of the Florida Panhandle. [6]

Erigeron vernus grows in moist locations in flatwoods and savannahs, and sometimes in ditches and by roadsides. It is a biennial or perennial herb up to 50 centimeters (20 inches) tall, producing rhizomes and a woody underground caudex. The inflorescence is made up of 1–25 flower heads in flat-topped arrays. Each head contains 25–40 white ray florets surrounding numerous yellow disc florets. [3] [7]
