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.[3]
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. [4] It has been noted that E. vernus is abundant in areas with hog rooting. [5] 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.[6]
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.[4]
Phenology
Generally, E. vernus flowers from late March until June.[2] It has been observed flowering January through July and September. [7]
Fire ecology
E. vernus is commonly found in fire-dependent pinelands.[6] It has been considered fire-stimulated. It largely flowers after a recent burn, particularly in pine savanna habitats. [5]
Use by animals
E. vernus has poor forage value.[8] This species supports conservation biological control through attracting predatory or parasitoid insects that in turn prey on pest insects.[9]
Conservation and Management
This species is imperiled in Virginia, and possibly extirpated in Washington D.C.[10]
