Symphyotrichum subulatum (formerly Aster subulatus), commonly known as eastern annual saltmarsh aster or, in Britain and Ireland where it is naturalized, annual saltmarsh aster,[7] is an annual plant in the family Asteraceae native to the eastern United States and the Gulf Coast to Texas.[8] The species grows primarily in coastal salt marshes, although in the Ozarks it occurs as a non-marine weedy variety.[9]
Description
Symphyotrichum subulatum is an annual forb that possesses a single erect stem that can reach up to 1 meter (3 feet 3 inches) in height. The stem, along with its thin green to dark green leaves, are both hairless. The sheathing base-blades of the leaves are ovulate, and the margins are entire.[10]
The top of the stem extends into a raceme inflorescence. The heads open up into bright yellow disc florets that are surrounded by ray florets that vary in color from white to lavender. From Wikipedia, the free encyclopedia
