There is no shortage of accessible information on Louisiana irises today. With search engines such as Google, using the search term "louisiana iris" will turn up many sources. There are several especially good websites that are rich with material on Louisiana irises or have more specific links to that material. A few are listed below.
By no means is all the good information about Louisiana irises available in digital format. Society For Louisiana Irises publications undoubtedly contain the most extensive material, and they in fact are the sources for much of what is found on the web. The Society's book, The Louisiana Iris, 2nd edition, is the definitive reference. The Society also publishes occasional "Special Publications" that focus in depth on topics related to Louisiana irises. Information on the book and other available Society publications can be found on the SLI website listed below.
The Society also publishes the quarterly magazine Fleur de Lis which is mailed to members. It is well worth the price of SLI membership if you want to keep up with the latest on what is happening in the Louisiana iris world. It is a beautiful publication with lots of color pictures to enjoy.
Society For Louisiana Irises. The Society is "the" organization on Louisiana irises, formed in 1941. Originally, it was more of a local organization with membership dominated by people from Louisiana and to some degree Texas. Now the Society is an international organization that reflects the breadth of interest in Louisianas and the huge portion of the globe in which they will grow well.
American Iris Society. AIS is devoted to irises of all types, and the Louisiana iris species are just five of over two-hundred in the world. The Society For Louisiana Irises has joined AIS as one of its sections.
Louisiana Iris Inspiration. The "Inspiration" page of the Zydeco Louisiana Garden Iris website has assembled a wide variety of links on Louisiana iris topics.
Species Iris Group of North America. SIGNA is devoted to growing and study of all the species of irises in the world. Its website contains a Species Database and the group sponsors an annual Seed Exchange. Not all species of iris will grow well along the Gulf Coast, but some will.

The species section of Zydeco Louisiana Iris Garden has pages devoted to each of the five Louisiana iris species. Several other websites have information on the species. A Google search by the species names will turn up quite a few additional sources: Iris hexagona, Iris brevicaulis, Iris fulva, Iris giganticaerulea, and Iris nelsonii.
Many of the nurseries that sell Louisiana irises also provide information on them. The Sources page on this site contains links to the ones that have websites.
