Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow . Louisiana irises have been the subject of major breeding efforts – some natural occurring and others the results of human crosses between several native America iris species. Sadly, their natural habitat – the bogs of Louisiana – has been dramatically reduced in size. The good news is you can help ensure their survival by adding them to your garden. Although they’ll grow happily in a foot of water they’ll do fine
