Taxonomic notes

Synonyms: Liatris graminifolia; Laciniaria graminifolia (Walter) Kuntze[1]

Varieties: L. graminifolia var. graminifolia; L. graminifolia var. lasia Fernald & Griscom; L. graminifolia var. racemosa (A.P. de Candolle) Venard; L. graminifolia var. typica; L. graminifolia var. dubia (Barton) A. Gray[1]


This species is abundant where it is found.[2]

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


The range of L. pilosa extends from New Jersey, Deleware, and Pennsylvania, then south to South Carolina.[1]



This species is found within well-drained stands of longleaf pine, sandhill slopes, and mixed hardwood-pine flatwoods as well as disturbed areas such as clear-cut slash pine plantations.[2] It has been observed to grow in open light conditions in red, sandy clays.[2]

L. pilosa became absent in response to soil disturbance by heavy silviculture in North Carolina and military training in west Georgia. It has shown resistance to regrowth in reestablished longleaf pinelands that were disturbed by these practices.[3][4]


This species has been observed flowering from September through October and fruiting in October.[2]

Fire ecology

This species grows in areas that are burned,[2] as populations of Liatris pilosa that have been known to persist through repeated annual burns.[5][6]

Conservation, cultivation, and restoration

L. pilosa should avoid soil disturbance by heavy silvilculture and military training to conserve its presence in pine communities.[3][4]
