 “The Island” is a space in City  
 Park where the Greater New Orleans  
 Iris Society grows and propagates  
 irises as part of SLI’s Species  
 CONVENTION 
 INFORMATION 
 Preservation Project. The club also grows species plants  
 for re-introduction into the wild. In addition, a wide variety  
 of cultivars are grown on the Island—kept for donation  
 and club sales—but the Species Preservation Project  
 has evolved as a  
 major focus of the  
 considerable effort  
 in the roughly one  
 acre plot. Around 100  
 different forms of Iris  
 fulva, giganticaerulea,  
 nelsonii, brevicaulis,  
 and hexagona are  
 entering their second  
 year on the island,  
 mostly growing in  
 seven-gallon pots in  
 retention pools, or  
 “iris paddies,” if you  
 prefer.  
 The design  
 I. nelsonii at City Park 
 of the Species Preservation Project calls for stewards  
 around the country to assume responsibility for growing  
 and maintaining a list of designated species forms. Some  
 irises have been distributed, but because of the availability  
 of space and support, the island has become an informal  
 “ground zero” for the Project. At present, there is no spot  
 in the country where one can see as wide a range of wild  
 Louisiana iris forms. 
 The island is no more than a ten-minute drive from the  
 Sculpture Garden and other tour stops in City Park, but, fair  
 warning, it is primarily a work area, not a manicured garden.  
 The site is pretty enough—sitting on the edge of a lagoon in  
 the park and looking across the water to a newly restored  
 golf course—but much of the immediately surrounding  
 space is used for outdoor storage and much is simply  
 undeveloped. The area in which the irises grow is fenced  
 and not open to the public. With special permission and  
 caveats, however, it will be on the AIS/SLI garden tours. 
 BOTANIC GARDEN IN BATON ROUGE 
 The Louisiana irises in the Botanic Garden in  
 Independence Park in Baton Rouge originated with the  
 efforts of the late Joseph Mertzweiller, a major hybridizer  
 and guiding force in SLI. Mertzweiller conceived of the iris  
 garden and donated the irises at the core of the original  
 planting, most of which survive in a well planned setting  
 that makes them readily accessible to the public. There is  
 no charge for admission to this garden, which also features  
 daylilies, roses, herbs, camellias, crape myrtles, and gingers.  
 Original plans for the garden called for the construction  
 of an “Iris Pavilion.” With admirable long term adherence  
 to the plan and the support of volunteers as well as Baton  
 Rouge Recreation and Parks, the Pavilion now sits in a  
 prominent place in the Garden.  
 The Garden will feature Guest Irises for the Convention  
 and other recent cultivars as well as many of Joe  
 Mertzweiller’s tetraploid and diploid irises. A nice mix of old  
 and new cultivars
