A description of Sisyrinchium nashii is provided in The Flora of North America.


Sisyrinchium nashii exists throughout the southeastern coastal plain, but is found primarily in peninsular Florida with disjunct populations in the Bahamas.[1]



In the Coastal Plain in Florida and Georgia, S. nashii occurs in limestone glades, longleaf pine/scrub oak communities, longleaf pine/wiregrass flats, slashpine woodlands bordering a tidal marsh, Cyrilla-Cliftonia thickets, and xeric oak/saw palmetto scrubs. Soil types include loamy sand, sand, and sandy loam.[2]

Associated species include Sarracenia minor, Calopogon, Schoenus nigricans, Sporobolus vaginiflorus, Dichanthelium commutatum, Polygala boykinii, and Echinacea purpurea.[2]


Sisyrinchium nashii flowers March through April[3] and fruits April through May.[2]

Fire ecology

S. nashii has been observed growing in frequently burned longleaf pine/wiregrass communities.[2] Populations have been known to persist through repeated annual burning.[4]


Sisyrinchium nashii was observed at the Archbold Biological Station to host sweat bees such as Lasioglossum coreopsis (family Halictidae).[5]

Conservation, cultivation, and restoration

Cultural use

Historically, this species was used by the Miccosukee Indians as an analgesic and for moving sickness.[6]
