The group that consists of the Louisiana Irises has been termed Hexagonae. Hexagonae is made up of 5 species: Iris hexagona, Iris fulva, Iris brevicaulis, Iris giganticaerulea, and Iris nelsonii.

Louisiana Irises are herbaceous perennial plants that grow to be approximately 2-3 feet in height. They produce underground rhizomes that serve as storage organs and as mechanisms for vegetative reproduction. Leaves are green, basal, and sword shaped.

The flowers are beardless and distinctly triangular in shape when viewed from above (three petals, three stamens, three pistils etc.). Flowers are very colorful, ranging from blues to pinks to yellow.

Louisiana irises can grow in shallow waters and along water edges.
