Aster family (Asteraceae). White heath aster is a hardy perennial with an extensive root system of rhizomes and stolons. This bushy plant grows to be 0.5 to 1 m tall and can have a 30 cm spread. Leaves are narrow (1cm wide) and linear (7 cm long), resembling the leaves of heather. At the time of flowering, most leaves drop except for those directly beneath the flower head. The remaining leaves are reduced to bracts. One plant can produce up to 100 flower heads. Ray flowers are white-to-pink, center disc flowers are yellowish-to-purple. Seeds are achenes that have tufts of white bristles to help them blow away with the wind. Flowering takes place August through November.
