Noteworthy Characteristics

Symphyotrichum puniceum, commonly called glossy-leaf aster, is a Missouri native that typically occurs in the swampy ground of spring-fed meadows in the eastern Ozark region. An erect, tall-growing species which grows to a height of 4-8'. Small but abundant flowers (to 1.5" across) with light violet blue to purple rays and yellow center disks appear in leafy clusters in autumn. Glossy, lance-shaped leaves clasp the stems. A late blooming aster that still looks fresh at time of first frost. Attractive to butterflies.

Genus name comes from the Greek symph meaning coming together and trich meaning hair in possible reference to the flower anthers.


No serious insect or disease problems.
