Liatris aestivalis, also known as the summer gayfeather, is a plant species in the family Asteraceae and genus Liatris. The specific epithet, aestivalis, is derived from Latin and means "pertaining to the summer".[1]

Plants have dark-purple colored flowers in dense heads that are closely grouped together, forming a cylindrical-shaped spike-like collection surrounding the stems. The basal and cauline leaves have one nerve and are linear to linear-lanceolate in shape. It flowers in July and August, sometimes into September. The seed are produced in cypselae fruits that are 4.5 to 6 millimeters long with feathery bristle-like pappi.[2]
