Field notes

Aster is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 170 species, all but one of which are restricted to Eurasia; many species formerly in Aster are now in other genera of the tribe Astereae. Aster amellus is the type species of the genus and the family Asteraceae.

The name Aster comes from the Ancient Greek word ἀστήρ (astḗr), meaning 'star', referring to the shape of the flower head. Many species, varieties, and hybrids, sometimes known as Michaelmas daisies for their late blooming, are popular as garden plants because of their attractive and colourful flowers. Aster species are used as food plants by the larvae of a number of Lepidoptera species.
