Taxonomic notes
Synonyms: Carduus nuttallii (A.P. de Candolle) Pollard.[1]
Varieties: none.[1]
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.[2][3] It can be distinguished from other Cirsium by having branched and many-headed stems.[4]
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.[2][5]
Cirsium nuttallii is an indicator species for the Calcareous Savannas community type as described in Carr et al. (2010).[6]
Phenology
Cirsium nuttallii has been observed flowering April through July with peak inflorescence in June and with white to pink flowers.[2][7]
Seed bank and germination
It produces a large number of seeds and has been observed to self-sow freely.[2][8]
Pollination
Cirsium nuttallii has been observed at the Archbold Biological Station to host bees from the Apidae family such as Apis mellifera and Bombus griseocollis, sweat bees such as Halictus poeyi (family Halictidae), and leafcutting bees such as Lithurgus gibbosus (family Megachilidae).[9]
Herbivory and toxicology
The seeds are eaten by birds, but avoids herbivory from deer.[10] It is the larval host to the little metalmark butterfly.[11]
Conservation, cultivation, and restoration
Global Conservation Status: G5.[12]
Cultural use
The leaves and stems can be cooked, so keeping it as a potherb is a possibility.[13]
