Taxonomic Notes

Synonyms: none.[3]

Varieties: none.[3]

Description

E. vernus is a perennial forb/herb of the Asteraceae family native to North America. [1] Average maximum root depth was found to be 9.5 cm, and average root porosity was found to be 12.5 percent.[4] It also has a long-lived life cycle.[5]

Distribution

E. vernus is found along the southeastern coast of the United States from Louisiana to Virginia.[1] It is considered a southeastern coastal plain endemic species.[6]

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. [7] It has been noted that E. vernus is abundant in areas with hog rooting. [8] It is listed by the USDA Natural Resources Conservation Service as an obligate wetland species that only can be found in wetland habitats.[1] In Florida, E. vernus is considered an indicator species of lower panhandle savannas, and is a common member of panhandle seepage savannas.[9]

Associated species include Sarracenia flava, Rhynchospora oligantha, Aristida stricta, Serenoa repens, Eragrostis refracta, Juncus abortivus, Juncus megacephalus, Juncus debilis, Rhexia virginica, Lachnanthes caroliana, Ludwigia linearis, Hypericum fasciculatum, and others.[7]

Erigeron vernus is an indicator species for the Lower Panhandle Savannas community type as described in Carr et al. (2010).[10]

Phenology

Generally, E. vernus flowers from late March until June.[2] It has been observed flowering January through July and September. [11]


Fire ecology

E. vernus is commonly found in fire-dependent pinelands.[9] It has been considered fire-stimulated. It largely flowers after a recent burn, particularly in pine savanna habitats. [8]

Herbivory and toxicology

E. vernus has poor forage value.[12] This species supports conservation biological control through attracting predatory or parasitoid insects that in turn prey on pest insects.[13]


Conservation, cultivation, and restoration

This species is imperiled in Virginia, and possibly extirpated in Washington D.C.[14]
