Thanks to all who have answered so far. I do not know the varietal name, but I suspect 'Black Gamecock' is a possibility. What I really wanted to know is whether it belongs to I. brevicaulis as a varietal or whether it might be a hybrid of some sort. People use the term 'Louisiana Iris' somewhat loosely. As I read it, this group includes several species. Thanks Andrew My guess would be Black Gamecock which shows a lot of Iris brevicaulis influence for a Louisiana hybrid in flower shape and size but is much darker and richer in color such as the photo shows. -- Alani Tallahassee, Florida
