Also known as bushy aster, rice button aster is a perennial herbaceous wildflower. Like other Symphyotrichum species, it is a profuse bloomer. Its flowers are small (3/8- to 3/4-inch in diameter) and borne in terminal panicles. Ray florets vary in color from white to pink to lavender. Disk florets are yellow to reddish and may fade as the flower ages. Bracts are smooth and whitish. Leaves are linear, sessile and alternately arranged. Stems are slim and branched. 

Rice button aster occurs naturally in sandhills, pine flatwoods and hammocks. It blooms primarily in September through December, although it has been known to bloom throughout the year. Rice button aster attracts many pollinators, particularly butterflies and native bees. It is the larval host plant for the pearl crescent butterfly.
