Liatris squarrosa, commonly called the scaly blazingstar, is an herbaceous perennial plant native to eastern and central North America, with most populations in the Southeastern United States. It is a somewhat conservative species, often found in dry or rocky areas of native prairie and savanna vegetation. It produces purple flowerheads in the summer.
