|Natural range of Erigeron quercifolius from USDA NRCS Plants Database.|
Common name: Oakleaf fleabane
The common name, oakleaf fleabane, is due to the basal leaves being lobed like some oaks.
A description of Erigeron quercifolius is provided in w4 The Flora of North America.
E. quercifolius can be a winter annual, biennial or short live perennial, depending on environmental conditions. Basal leaves have a deeply notched marith yellow-green leaves that are rough to the touch. Flower stalks emerge from the center of the basal rosette and can reach about 12-24 inches tall by early summer. The flower heads are small and are composed of many thin, ray petals surrounding a rounded yellow disc. Flowers can be blue, white or pink.
E. quercifolius can be found in wetland depressions, wet pinelands, dry turkey-oak pinelands, pine flatwoods, moist open hammocks, and peaty soils of cypress-gum swamps. It is a quick to colonize openings and disturbed areas such as roadsides, vacant lots, open fields, and drainage ditches. Soils include loamy sand, peaty soil, and shell rock.  Associated species include Helenium pinnatifidum, Parietaria praetermissa, Micromeria brownei, Spermacoce assurgens, Galium hispidulum, Vicia floridana, Commelina diffusa, Rumex verticillatus, Galium tinctorium, Boehmeria cylindrica, and Saururus cernuus.
