This is a wild flower of Eastern North America, and one of the few native iris species in garden cultivation. Although happiest at the waterside, or actually growing in shallow water, plants will also perform well under average border conditions. Clumps of tall sword-like leaves are produced, bearing medium-sized flowers with bright violet-blue, ruffled petals. Might actually begin to naturalize in waterside areas that are to its liking. In smaller water features, consider growing this in large pots submerged to the rim. Clumps are easily divided in the autumn. CAUTION: Harmful if eaten.
USDA Zones: 2-9
