Iris tridentata differs from all other native Iris species of the southeastern United States in having petals (or inner whorl of the perianth) only 1 to 2 cm long, therefore looking like three "teeth" ....hence the species name "tridentata". It is a plant of wetland pine savannas of the Coastal Plain from southeastern North Carolina south to the Florida Panhandle, with rare disjuncts in "coastal plain type" habitats in central Tennessee.
