Louisiana irises constitute a unique group in the iris family. Among all the iris, Louisiana's have exceptional variety in color and in form.
They exhibit an incredibly broad range of color and are considered very significant in providing the color red to the iris spectrum.
An equally wide variety of forms, when combined with the color range, make for truly great horticultural opportunities.
Louisiana irises belong to the subsection Apogon (without beard or beardless), series Hexagonae of the genus Iris. They are derived from five species, most of which are indigenous to a limited area of south Louisiana and the Gulf Coast marsh areas between Texas and Florida. Two species, Iris brevicaulis and I. fulva, extend the range northward up the Mississippi Valley. Iris hexagona inhabits the southern Atlantic and Gulf Coasts, but by far, the greatest concentration is in the state of Louisiana, hence the name Louisiana Irises.
The genesis of the Society for Louisiana Irises began in 1941, when a small group of dedicated South Louisiana growers and collectors came together in with the intention of preserving and promoting interest in this captivating native plant. In the decades that followed, plant breeders took the original species and developed the beautiful hybrid Lousiaiana iris of today. The Society for Louisiana Irises continues to promote the use of Louisiana irises both in the garden and the landscape and the preservation of the native species in their natural habitat.
