Noteworthy Characteristics
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).
