Symphyotrichum parviflorum (formerly Symphyotrichum subulatum var. parviflorum) is an annual and herbaceous plant commonly known as southwestern annual saltmarsh aster. [4] It is native to Mexico, the Caribbean, most of Central America, Ecuador, and the southwestern United States.
Southwestern annual saltmarsh aster usually flowers from July through November, but sometimes into January. It has white, sometimes pink, ray florets surrounding yellow disk florets. As the plant is drying after pollination, each ray floret curls into 1 to 2 coils. [5]
The basionym of Symphyotrichum parviflorum is Aster parviflorus, and it was first described by Christian Gottfried Daniel Nees von Esenbeck ("Nees") in 1818. [3] It also has been called Symphyotrichum expansum [2] and Symphyotrichum subulatum var. parviflorum. [5]
Symphyotrichum parviflorum is native to Mexico, the Caribbean, most of Central America, Ecuador, and the southwestern United States. It is an introduced species in central Europe. [1] Flora of North America reports an introduction of the species in Hawaii and Japan. It grows in marshy habitats and roadsides at 0–1100 meters (0–3609 feet) (sometimes up to 4000 m (13000 ft)), and it is often considered weedy. [5]
As of December 2021 [update] , NatureServe gives no global status rank to this plant. It does rank it as Critically Imperiled in Nevada. [6]
