Dear PBS, Iris laevigata is one of the MOST HARDY of all Iris species I grow it in Kansas City in tubs that stay outdoors all year even down to single digits (F) when the containers are frozen solid in ice.They never NEVER fail to bloom. It is also the MOST WATER LOVING of all Iris species. These do best if partially or all submerged in water all year long. They suffer if allowed to dry at all. The most active hybridizer of Iris laevigata is Chad Harris, owner of Mt. Pleasant Iris Farm. I urge anyone interested in adding these selections to their garden to look at his listing of available cultivars. http://mtpleasantiris.com/catalog-mt-pleasant-iris… If planted properly in water they are trouble free and very rewarding.
