Symphyotrichum ericoides, syn. Aster ericoides (common name white aster or heath aster), is a species of flowering plant in the family Asteraceae, native to much of North America, as well as northern Mexico. It has also been introduced to many areas beyond its native range.
Confusingly, plants sold in the horticultural trade labeled as Aster ericoides, the old name of the plant, are almost invariably cultivars or hybrids involving the European garden plants Symphyotrichum dumosum, S. lateriflorum, S. pilosum or S. racemosum, a mistake that has apparently occurred continuously since the 19th century.
Asters are tough plants, though they can be subject to fungal infections, especially if not planted in open, sunny conditions where the soil is not too damp. They are valued in the garden for providing late season flower colour in shades of blue, pink and white. The following cultivars of A. ericoides have gained the Royal Horticultural Society's Award of Garden Merit:-
