Nabalus crepidineus, commonly called the nodding rattlesnakeroot, [1] is a species of flowering plant in the family Asteraceae. It is native to the United States, where it is found in the Midwest and Upland South regions. [2] Its natural habitat is in bottomland and mesic forests, and along streambanks. [3]
It is a perennial flowering plant growing up to 3 m (9.8 ft) tall. It produces white (sometimes yellow) flowers in late summer and autumn. [4] [3] It is most easily seen in the spring, where it can forms large colonies of sterile basal rosettes. These rosettes are typically epehemeral, with proportionally very few persisting beyond mid-summer into the flowering period. [3]
Molecular and morphological evidence indicates that Nabalus crepidineus and its North American relatives are best treated in a separate genus from Prenanthes. This treatment became widely adopted in the 2010s. [5] [6]
This plant occurs from western New York west to southeastern tip of Minnesota, south to Arkansas and Tennessee. [2] Although widespread, it is considered infrequent throughout its range. [7]
In Arkansas, this species occurs in 12 counties, mostly in the Arkansas Ozarks. [8]
