Erigeron (/ɨˈrɪdʒərɒn/)[2] is a large genus of plants in the daisy family.[3] It is sometimes confused with other closely related genera, Aster and the true daisy Bellis. The genus has a cosmopolitan distribution in dry, mountainous areas and grassland, with the highest diversity in North America.[4][5][3][6][7]
Contents
Etymology[edit]
The most widely used common name, fleabane, is shared with related plants in several other genera. It is derived from the belief that the dried plants repelled fleas.[citation needed] The generic 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.[8] The Ancient Greek word γέρων is masculine,[9] so that specific epithets should have masculine endings (e.g. glaucus). However, authors have incorrectly used neuter endings (e.g. glaucum), as Augustin Pyramus de Candolle did in his 1836 account of the genus.[10]
Description[edit]
The species may be annuals, biennials or perennials. They are well-branched 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).
Cultivation[edit]
Many species are used as ornamental plants, with numerous named cultivars such as 'Wayne Roderick', 'Charity', 'Foersters Liebling' and 'Dunkelste aller' ("The darkest of all" with semi-double, deep violet flower heads).[11]
Ecology[edit]
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.
