About Nabalus crepidineus (Michx.) DC.
Nabalus crepidineus (Michx.) DC. is a perennial flowering plant that can grow up to 3 m (9.8 ft) tall. It produces white, sometimes yellow, flowers in late summer and autumn. The species is most easily observed in spring, when it can form large colonies of sterile basal rosettes. These rosettes are typically ephemeral, with proportionally very few persisting beyond mid-summer into the flowering period. Molecular and morphological evidence shows that Nabalus crepidineus and its North American relatives are best placed in a separate genus from Prenanthes. This classification became widely adopted during the 2010s. In terms of range, this plant grows from western New York west to the southeastern tip of Minnesota, and south to Arkansas and Tennessee. While it is widespread, it is considered infrequent across its entire range. In Arkansas, this species is found in 12 counties, most of which are located in the Arkansas Ozarks.
