Symphyotrichum urophyllum (formerly Aster urophyllus) is a species of flowering plant in the family Asteraceae native to eastern North America, commonly known asarrowleaf aster.[3]
Symphyotrichum urophyllum is a perennial, herbaceous species between 40 and 120 centimeters (1+1⁄4 and 4 feet) tall. Plants are cespitose, with 1–5 erect stems emerging from the same point. The broad, thin, toothed leaves are arrow-shaped, with a broadly winged petiole. The dense, pyramidal inflorescence of composite flowers is distinctive.[4] The ray florets are white and the disc florets are white to cream becoming pink.[3]
Taxonomyedit
Symphyotrichum urophyllum was formerly included in the large genus Aster as Aster urophyllus. However, this broad circumscription of Aster is polyphyletic and the North American asters are now mostly classified in Symphyotrichum and several other genera.[5]
The taxonomic status of this species has been unstable, and it has been treated as Symphyotrichum sagittifolium, a name now considered to be synonymous with Symphyotrichum cordifolium. Most sources now use S. urophyllum to refer to this species.[3][6]
