Aster is a genus in the family Asteraceae that includes 180 flowering perennial species. It formerly contained over 600 species, but genetic and morphologic research in the 1990s proved that many “asters” belong in different genera.
This primarily affected New World species, with all but one being native to Europe and Asia. Species from the Americas have been reclassified in the genera Almutaster, Canadanthus, Doellingeria, Eucephalus, Eurybia, Ionactis, Oligoneuron, Oreostemma, Sericocarpus, and Symphyotrichum. All still belong to the same tribe of Astereae.

These flowering plants typically grow to three or four feet in height, but some species and cultivars have a mounded and compact habit instead. They have various shades of pink, blue, purple, and white blooms.
