Hartwrightia is a genus of North American flowering plants in the tribe Eupatorieae of the family Asteraceae.

[6] Hartwrightia is classified in the subtribe Liatrinae of the tribe Eupatorieae, along with, for example, Liatris, Carphephorus, and Garberia.

[7] Molecular data, while placing Hartwrightia firmly within subtribe Liatrinae, give mixed results regarding its closest relative.

It is found in open areas, for example in pine flatlands,[9] but is not tolerant of grazing or solid forest cover.

[1] The seed is a sticky achene without the large pappus which would suggest wind dispersal, so it is presumed to be transmitted by animals.
