Etymology
The specific name amellus is first used in the Georgics (Book IV, 271–280), a poem of the Latin poet Publius Vergilius Maro (70 BCE – 19 BCE), but the etymology is obscure and uncertain.
The English common name derives from the flowers being in bloom during Michaelmas (the Feast of St. Michael the archangel).

Description
Aster amellus reaches on average a height of 20–50 centimetres (7.9–19.7 in). The stem is erect and branched, the leaves are dark green. The basal leaves are obovate and petiolated, the cauline ones are alternate and sessile, increasingly narrower and lanceolate. The flowers are lilac. The flowering period extends from July through October. The hermaphroditic flowers are either self-fertilized (autogamy) or pollinated by insects (entomogamy). The seeds are an achene that ripens in October.
