Dedicated to the Louisiana Iris


Benny Trahan, Sr.


Charter GNOIS member Benny Trahan, Sr., passed away on December 15, 2021. He was a good friend and an important figure in the Louisiana iris world, notably for the collection and preservation of wild forms of the species.

Benny shared his experiences in two fascinating and highly recommended articles that are available online.

"Wild Louisianas: Still Out There, Still Beautiful, and More Endangered Than Ever"

We need help at our iris nursery!

We are asking our members and friends to give us a hand for a few hours on Thursdays between 9:00 - 11:00 AM. The may be some special Saturday volunteer days from time to time.

There will be tasks at various levels and including some in the shade. There is always weeding to do, but we also will be dividing and labeling pots of irises and propagating new plants from old rhizomes.

Everyone who helps will get a free Louisiana iris rhizome!

Please bring gloves.

Spring bloom great, but virus hampered eventsdivider

The Sculpture Garden and the N.O. Botanical Garden were closed. The irises blooming in the wild were still accessible at places like the Town of Jean Lafitte's Boardwalk, the Northlake Nature Center, and many other spots.

The GNOIS planting in City Park, a working space, was gorgeous. Pictures from the season are frequently posted on Facebook. Follow the GNOIS page to see them and for timely information on activities and other information.

Our spring iris sale was cancelled due to the virus, but plans are being made to hold the sale soon.

Look for details here and on Facebook.

The sale is history, and it was a great success. We are leaving the ad up for now, because clicking on it will take you to pdf files of images of all the sale irises. If you have not seen these irises, you may enjoy downloading the pictures while they are still available. Most will be offered in future sales, but many new ones will be sold also. Stay tuned.
