Symphyotrichum patens, commonly known as late purple aster or spreading aster, is a perennial wildflower found in the eastern United States.[1][2]
Description
Sympyotrichum patens is a small (up to ~1m height) herbaceous plant with a spreading growth form. The leaves are ovate to oblong, clasping the pubescent stem.[2][3] The flowers are relatively small, less than 3 cm (1.2 in) in diameter, with light blue to violet petals and yellow centers.[3] It flowers between August and October.[3]
Taxonomy
The genus Symphyotrichum includes some 90 species that are often highly similar.[4] The title of a review of the Symphyotrichum patens complex begins with "Another review..." as a nod to the complexity of the topic.[5] The species was first formally described as Aster patens in 1789.[6] It was transferred to the genus Symphyotrichum in 1995 by Guy L. Nesom.[7] It is closely related to Symphyotrichum georgianum and Symphyotrichum phlogifolium.[5]
Several varieties have been named:[8][5]
- Symphyotrichum patens var. patens
- Symphyotrichum patens var. gracile (Hook.) G.L.Nesom
- Symphyotrichum patens var. patentissimum (Lindl.) G.L.Nesom
- Symphyotrichum patens var. terranigrum J.J.N. Campbell & W.R.Seymour
Distribution and habitat
A widely distributed species, S. patens can be found from southern Maine south and west to East Texas.[1] Plants are typically found in sunny to mostly sunny sites, including open woodlands.[9] Relatively little appears to be known about the species' ecology, with most literature being checklists that include S. patens.
