This rabbit-ear iris loves a good swim

Iris laevigata, also known as rabbit-ear iris, is an herbaceous perennial. It flowers in early summer, producing dark purple, violet or blue flowers that compliment the long, sword-like green leaves. I. laevigata should be grown in shallow water on the border of a pond or in a marshy area. It prefers a sunny or partially shady spot if it’s to thrive. Rabbit-ear iris is relatively slow growing, and is, therefore, not invasive of ponds. If no pond is available, it can be grown in a small aquatic environment within a container.
