Native from Maine south to Georgia, Iris prismatica is found growing in bogs and marshes. The narrow upright foliage forms rhizomatous clumps topped with narrow-petaled flowers in early May. Our selection of Iris prismatica is from divisions of a clone from Nash County, NC, having lovely violet-blue flowers with falls (the petals that don't stand upright) that display a nice central white pattern. Iris prismatica is an easy-to-grow, deer-resistant and hummingbird friendly native that should be in all gardens where moisture is adequate. In 5 years, you can expect a 3' wide patch.
