The species is native to the southeastern United States, the coastal plain in Virginia, Georgia, and the Carolinas.[2]Cirsium repandum is a biennial or perennial herb up to 80 cm (32 inches) tall. Leaves have small, narrow spines along the edges. Flower heads are sometimes produced one at a time, sometimes in small groups, each head with light purple disc florets but no ray florets. The species grows in sandy soils on sand hills or in pine barrens.[3] References1. ^The Plant List, Cirsium repandum Michx. {{Taxonbar|from=Q15596033}}{{Cynareae-stub}}2. ^Biota of North America Program 2014 county distribution map 3. ^Flora of North America, Sand-hill or coastal-plain thistle 3 : Cirsium|Flora of the Southeastern United States|Plants described in 1803 |
