Common name: Oakleaf fleabane

Taxonomic notes

Synonyms: none.[1]

Varieties: none.[1]

The common name, oakleaf fleabane, is due to the basal leaves being lobed like some oaks.[2]


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.[2] Flowers can be blue, white or pink.[3]


Erigeron quercifolius exists across the southeastern Coastal Plain region, but is primarily found in peninsular Florida with disjunct populations in the Bahamas.[4]



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. [2][5] 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. [5]


It has an inferior ovary[6] and flowers March through October. [5] Fruits are achenes[6]. In north Florida peak inflorescence has been observed in April.[7]


Erigeron quercifolius has been observed at the Archbold Biological Station to be visited by bees from the Apidae family such as Apis mellifera, Bombus impatiens and Epeolus pusillus, plasterer bees from the Colletidae family such as Colletes mandibularis, sweat bees from the Halictidae family such as Halictus poeyi, Lasioglossum tamiamensis, wasps from the Leucospididae family such as Leucospis robertsoni, L. slossonae, leafcutting bees from the Megachilidae family such as Coelioxys germana, Dianthidium floridiense, Dolichostelis louisae, Heriades leavitti, Megachile albitarsis, M. parallela and M. petulans, thread-waisted wasps such as Bicyrtes capnoptera (family Sphecidae) and wasps from the Vespidae family such as Euodynerus hidalgo and Pachodynerus erynnis.[8] Additionally, E. quercifolius has been observed to host ground-nesting bees from the Andrenidae family such as Andrena atlantica, Perdita boltoniae and P. nubila, bees such as Ceratina cockerelli (family Apidae), plasterer bees such as Hylaeus confluens (family Colletidae), and leafcutting bees such as Heriades leavitti (family Megachilidae).[9]

Herbivory and toxicology

It attracts predatory and parasitoid insects that will prey on pest insects. It is a host to thrips and aphids.[10]

Conservation, cultivation, and restoration

Cultural use

It is claimed that burning the foliage will chase away fleas and other pests.[11]
