The Louisiana Iris

Louisiana Irises are increasingly recognized as native plants well adapted to garden culture.  They also make fine water garden or rain garden plants and love aquatic or bog conditions. While sometimes referred to as water irises, their only real requirement is to stay damp and not dry out.  

Louisiana iris cultivars grow well across the country and the color range is the widest of all the iris groups.  Hybrids are derived from five North American species: I. brevicaulis, I. giganticaerulea,  I. fulva, I. nelsonii, and I. hexagona.  Fulva and brevicaulis occur naturally as far up the Mississippi Valley as the Great Lakes, which largely accounts for the cold hardiness of hybrid cultivars.

What You'll Find On This Site

This site is designed as a hub for resources on Louisiana irises.  It offers a wide range of information, pictures, recommendations and links on "Louisianas," as these irises are called. Take a look.

Zydeco Louisiana Iris Garden formerly sold the hybrid introductions of Patrick O'Connor of Metairie, Louisiana, as well as irises from many other hybridizers.  This Gallery previously was a catalog but now serves as a source of information on individual cultivars.  Beginning in 2014, many O'Connor irises will be available from Louisiana Iris Gardens.

  • The 2013 season is over.  It was the last in which Zydeco will have a catalog. All the extra time I anticipated after retirement from my "real" job did not materialize, and I am cutting way back to enjoy growing and hybridizing.
  • The Zydeco website will stay up as a source of information on Louisiana irises.
  • In the future, Louisiana Iris Gardens will handle my introductions.  Take a look at their catalog when it is updated next spring.   Louisiana Iris Gardens can also be found on Facebook.
  • The Society For Louisiana Irises will be holding its 2014 National Convention in New Orleans.  There are lots of great places to see Louisiana irises here.  Take a look at the Convention website.
