Simmond’s aster (Symphyotrichum simmondsii) is endemic to the Southeast coastal plain and while recorded from the Carolinas to Alabama, it is most prevalent throughout peninsular Florida. Occupying various habitats from moist to dry, it forms colonies via long underground rhizomes and typically blooms from October through January.

Small flowers are composed of 18–38 pale lavender to lilac rayflorets and 24–37 disk florets that turn reddish with maturity. Leaves are oblanceolate, scabrous and arranged alternately. Stems are rigid and range from sparsely scabrellous to glabrous. (Click here for a detailed botanical description)
