Description
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.[1][2] It can be distinguished from other Cirsium by having branched and many-headed stems.[3]
Distribution
Ecology
Habitat
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.[1][4] Soils include loamy sand and sandy loam.[4]
Phenology
Cirsium nuttallii has been observed flowering April through July with peak inflorescence in June and with white to pink flowers.[1][5]
Seed bank and germination
It produces a large number of seeds and has been observed to self-sow freely.[1][6]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Cirsium nuttallii at Archbold Biological Station:[7]
Apidae: Apis mellifera, Bombus griseocollis
Halictidae: Halictus poeyi
Megachilidae: Lithurgus gibbosus
Use by animals
The seeds are eaten by birds, but avoids herbivory from deer.[8] It is the larval host to the little metalmark butterfly.[9]
Conservation and management
Global Conservation Status: G5.[10]
