Cirsium texanum is a species of plants in the tribe Cardueae within the family Asteraceae found in North America. Common names include Texas thistle, Texas purple thistle or southern thistle.[2] The species is native to northern Mexico (Coahuila, Durango, Nuevo León, San Luis Potosí, Tamaulipas) and the southern Great Plains of the south-central United States (primarily Texas, Oklahoma, and eastern New Mexico with additional populations in Louisiana, Arkansas, and Missouri).[3][4]
Cirsium texanum 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.[2]
