Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. For many years the irises we grew in our yards were Siberian, Dutch, German or Japanese irises. Now, however, with the new interest in native plants, it’s easy to find North American species that are ethically collected and propagated. For damp areas or in a good irrigated garden soil, Louisiana irises are ideal. These are vigorous plants with no pests or disease problems, they are even deer resistant should would be beautiful at the edge of a pond.
