Description

E. vernus is a perennial forb/herb of the Asteraceae family native to North America. [1]

Distribution

E. vernus is found along the southeastern coast of the United States from Louisiana to Virginia. [1]

Ecology

Habitat

E. vernus proliferates in wet savannas, seepages, and interdunal swales. [2] Specimens have been collected from edge of pond, dry loamy sands, wet pine flatwoods, hardwood swamp, peaty ditch, cypress swamp, prairie, hillside bog, and disturbed areas such as next to a track field and roadside ditches. [3] It has been noted that E. vernus is abundant in areas with hog rooting. [4] It is listed by the USDA Natural Resources Conservation Service as an obligate wetland species that only can be found in wetland habitats.[1]

Phenology

Generally, E. vernus flowers from late March until June.[2] It has been observed flowering January through July and September. [5]

Fire ecology

E. vernus has been considered fire-stimulated. It largely flowers after a recent burn, particularly in pine savanna habitats. [4]

Use by animals

E. vernus has poor forage value.[6] This species supports conservation biological control through attracting predatory or parasitoid insects that in turn prey on pest insects.[7]
