The group has a special use permit from USFWS to collect these iris through May-2016, thought to be the species known as Dixie Iris (Iris hexagona), one of five "beardless iris" species which are collectively referred to as Louisiana Iris. The species is not common in Brazoria Co., and this population represents the extreme southwestern edge of its native range, which extends along the Gulf Coast from SE Texas to Florida. It favors sunny shallow-marsh areas, and grows thickly together to a height of about 3 to 3.5 feet. The flowers are primarily blue-purple in color, occurring on stems just taller than the sword-like leaves, although rarely the color can be lighter to almost a pure white. Pollinators tend to be native bumblebees, attracted by the yellow throat. Consequently, the species has been identified as useful for the shallow shelf areas of the specially-designed "wet bottom" stormwater retention ponds. A number of locations (patches) have been identified at SBNWR, and future workdays will be used to collect at additional locations for the sake of genetic diversity.
