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]
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. [11]
The species' full scientific name is Symphyotrichum subulatum (Michx.) G.L.Nesom. As of December 2021 [update], three varieties of S. subulatum were accepted by Plants of the World Online (POWO), with S. subulatum var. subulatum as the autonym: [3]
The varieties S. subulatum var. ligulatum (Shinners) S.D.Sundb. and S. s. var. parviflorum (Nees) S.D.Sundb., as of December 2021 [update], are accepted at the species level by POWO as Symphyotrichum divaricatum (Nutt.) G.L.Nesom [12] and Symphyotrichum expansum (Poepp. ex Spreng.) G.L.Nesom, [13] respectively. As of December 2021 [update], S. s. var. parviflorum (Nees) S.D.Sundb. is accepted at the species level by Catalogue of Life (COL) as Symphyotrichum parviflorum. [14]
Symphyotrichum subulatum is a terrestrial species that will typically grow among grasses of any kind. [10] It is found in salt marshes, pond margins, sloughs, swamps, crop field margins, lawns, and roadsides. It is thought to be especially prevalent in these areas because of a tolerance to saline soils and mowing. [15] It is native to the eastern and Gulf Coast areas of the United States. It is also common across Mexico, the West Indies, Bermuda, Central America, and South America, depending on variety. [11]
According to the Lady Bird Johnson Wildflower Center, eastern annual saltmarsh aster can be planted to attract butterflies and has value for native bees. [16]
