] of flowering plants in the family Asteraceae. The genus has a cosmopolitan distribution with the highest species diversity in North America, where 173 species occur.

The most widely used common name, fleabane, is shared with related plants in several other genera; another common name is summer starwort. The common name is derived from the belief that the dried plants repelled fleas, whilst the name erigeron is derived from the Greek (eri = early; geron = old man), a reference to the appearance of the white hairs of the fruit soon after flowering.

The species are annuals, biennials or perennials. They are well-branched plants with erect stems, characterized by their numerous white, lavender or pink ray flowers and yellow disc flowers. Some members of this group have no ray flowers. The pappus (= modified calyx, forming a crown) is shorter than in "Aster", and consists of bristles. The ray florets are narrower than in "Aster", but are clearly longer than the involucre (= whorled bracts).

Many species are used as ornamental plants, with numerous named cultivars such as 'Wayne Roderick', 'Charity', 'Dunkelste Aller' and 'Foersters Liebling'.

"Erigeron" species are used as food plants by the larvae of some Lepidoptera species including "Bucculatrix angustata", "Coleophora squamosella" (which feeds exclusively on "E. acris"), "Schinia intermontana", "Schinia obscurata" (both of which also feed exclusively on "Erigeron"), "Schinia sexata" (which feeds exclusively on "E. glabellus") and "Schinia villosa".
