Similar species (if any): Liatris aspera (Rough Blazingstar) and Liatris pycnostachya are the two most widely distributed Liatris species in Wisconsin. They can be distinguished from one another by the appearance of the bracts. L. aspera has bracts with a cup-shaped form, greenish-white in color, and with an irregular edge, whereas L. pycnostachya has bracts with a redish-pink color. The dense flowering spike of L. pycnostachya can aid in the identification of this species. 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, with the latter species having a rather limited range in the state.
