About

Erigeron () is a large genus of plants in the composite family (Asteraceae). It is placed in the tribe Astereae and is closely related to the Old World asters (Aster) and the true daisies (Bellis). The genus has a cosmopolitan distribution, and the highest diversity occurs in North America.

How to grow it

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).

Where it grows

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. Above-ground biomass of Erigeron in montane meadows decreases with decreased water availability/increased temperatures.
