Blue slender iris (Iris prismatica) is not the typical bearded iris (Iris germanica), though they are related. Blue slender iris grows in marshy areas. This perennial flower is limited to the eastern United States and planting zones 6a to 8b. Plant blue slender iris in full sun to partial shade in damp areas in your landscape such as along a drainage ditch or pond. Space the plants about 12 inches apart. Keep in mind that some people experience skin irritation handling the plant. This flower self-sows.
 
The bloom, which opens between April and July, is blue-violet in color and grows on a stem reaching 12 to 36 inches tall. The leaves resemble tall grass and grow 12 to 24 inches tall.
