Similar species (if any): The bracts of Liatris aspera with their cup shaped form in 4 to 5 layers, greenish-white in color, and with an irregular edge help to distinguish this species from other Liatris species in the state. In Wisconsin, Liatris spicata (Marsh Blazing-star, Dense Gay-feather) is a species of special concern, and Liatris punctata (Dotted Blazing-star, Dotted Gay-feather) is listed as an endangered species. Liatris aspera and Liatris pycnostachya (Prairie Blazing-star, Thick-spike Gay-feather) are the two most widely distributed Liatris species in Wisconsin. The latter species has redish-pink bracts.
