Sympyotrichum patens is a perennial and herbaceous flowering plant usually between 10 and 100 centimeters (14 and 3+14 feet) tall.[5] It has a spreading growth form, and the leaves are ovate to oblong and clasp the pubescent stem.[5][6] The flowers are relatively small, less than 3 centimeters (1+14 inches) in diameter, with light blue to violet ray florets and yellow disk florets. It flowers between August and October.[6]

Taxonomy

[edit]

The title of a review of the Symphyotrichum patens complex begins with "Another review..." as a nod to the complexity of the topic.[3] The species was first formally described and named Aster patens by Swedish botanist Jonas Carlsson Dryander and published by Scottish botanist William Aiton in 1789.[7] It was transferred to the genus Symphyotrichum in 1995 by American botanist Guy L. Nesom.[8] It is closely related to Symphyotrichum georgianum and Symphyotrichum phlogifolium.[3]

Several varieties have been named, with the basionym as Symphyotrichum patens var. patens:
