A description of Liatris chapmanii is provided in The Flora of North America.

L. chapmanii is a perennial species that grows from rounded to elongated corms.[3][4] The leaves are slightly curved, thin, and can be found along the flower stalk. The basal rosette is dense and has a whorled appearance. The puprle flowers are densely clustered along the flower stalk, with the stalk capable of reaching 3 feet tall.[2]


Liatris chapmanii is endemic to the east Gulf Coastal Plain in a narrow belt from southwest Georgia to southeast Louisiana and northwest Florida.[5]



In the Coastal Plain in Florida and Georgia, L. chapmanii can occur in longleaf pine sandhills and pine-oak-palmetto scrubs. It has been found in disturbed areas such as bulldozed pinelands and sandy fields. Soil types include loamy sand and red clay. Associated species include Quercus laevis, Ceratiola, Chrysopsis, Liatris gracilis, L. tenuifolia, Carphephorus odoratissimus, Balduina, Sporobolus, Lyonia, Myrica, Serenoa, Agalinis, and Dicerandra.[6]

Liatris chapmanii is an indicator species for the Panhandle Xeric Sandhills community type as described in Carr et al. (2010).[7]


L. chapmanii has been observed to flower in the month of June and August through October.[6][8] The seeds are produced in cypselae fruits that have feathery bristle-like pappi.[3]

Seed bank and germination

L. chapmanii occurs in pyrogenic scrub and sandhill communities and germination is stimulated by smoke.[9]


The following species were observed visiting flowers of Liatris chapmanii at the Archbold Biological Station:[10]
