Taxonomic notes

The specific epithet xerophyllum refers to the habitat this species grows in: well-drained sandy uplands.[1]


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


This species is endemic to Florida and southern Georgia.[1]



In the Coastal Plain in Florida, S. xerophyllum occurs surrounding limestone glades with wiregrass, open barrens, scrub oak-wiregrass sand ridges, pine-turkey oak flats, and interdune swales. It has also can be found in disturbed areas such as sandy parking lots and roadsides. Soils include sandy loam, loamy sand, sand, and loam. It grows in shaded environments.

Associated species include Carex fissa, C. vexans, Chrysopsis linearifolia, Andropogon virginicus, Aristida stricta, Pteridium aquilinum var. subcaudatum, Smilax auriculata and Panicum virgatum.[2]

Sisyrinchium xerophyllum is an indicator species for the Peninsula Xeric Sandhills community type as described in Carr et al. (2010).[3]


Flowers have six blue tepals, yellow bases and usually aristae tips. Flowers March[4] through November and fruits May through November.[2]

Seed dispersal

This species is thought to be dispersed by gravity.[5]

Fire ecology

S. xerophyllum has been observed to be a weak resprouter after fire. It decreases in frequency and abundance post fire.[6]


Sisyrinchium xerophyllum has been observed at the Archbold Biological Station to host sweat bees such as Lasioglossum nymphalis and L. placidensis (family Halictidae), and leafcutting bees from the Megachilidae family such as Anthidiellum perplexum and Megachile brevis pseudobrevis.[7]
