Cirsium carolinianum is a North American species of plants in the thistle tribe within the sunflower family. Common name is Carolina thistle or purple thistle or soft thistle or smallhead thistle. The species is native to the central and southern United States, from eastern Texas east to Virginia and the Carolinas, north to the Ohio Valley.
Cirsium carolinianum is a biennial herb up to 180 cm (6 feet) tall, with a relatively short taproot. Leaves have small, thin spines along the edge, much smaller than those of related species. There are usually several flower heads, with pinkish-purple (rarely white) disc florets but no ray florets.
