A description of Cirsium nuttallii is provided in The Flora of North America.
C. nuttallii is a biennial species that develops a deep taproot and basal rosette the first year, then shoots up a single, erect, glabrous stem. It can be distinguished from other Cirsium by having branched and many-headed stems.
In the Coastal Plain in Florida and Georgia, C. nuttallii can be found in loamy sand of pine savannas, Hymenachne depressions, and freshwater marsh banks. It will grow in sunny, open and disturbed habitats such as roadsides, railroad tracks, pastures, levees, highways, and upland fallow fields. Soils include loamy sand and sandy loam.
