    Refer to the Iris Encyclopedia page for culture of Japanese Iris. Irises (Iris) (see below)

    Excerpt from "Cultivation Of Japanese, Bog, Water and Species Beardless Irises" by Polly Kinsman. "Most of the water irises can be grown in or near a pond, but in areas that freeze they cannot have their rhizomes under water as it will suffocate the plant."
