Symphyotrichum ericoides, commonly called heath aster, is a Missouri native plant that typically occurs in open rocky woods, prairies and along roads and railroads. A bushy, somewhat compact plant with many-branched stems which typically grows 1' to 3' tall. Small, daisy-like flowers (1/2" across) are borne in profusion in spreading, often one-sided, dense sprays (racemes) in late summer to early fall. Ray flowers are usually white, but infrequently blue or pink and center disks are yellow. Distinctive leaves (to 3" long) are narrow (1/4" wide), rigid, linear and heath-like (hence the common name). Good cut flower. Attractive to butterflies.
Genus name comes from the Greek symph meaning coming together and trich meaning hair in possible reference to the flower anthers.
Specific epithet means resembling the genus Erica (heather).
‘Snow Flurry’ is a prostrate heath aster cultivar that typically grows to 4-6” tall and spreads along the ground to form a dense foliage mat. Small, single asters (to 1/2” diameter) with white rays and yellow centers.

Rock gardens where it can be sprawled along ledges and over rocks. Effective ground cover. Borders fronts, cottage gardens, open woodland gardens or wild/naturalized areas.
