Notes:  Siberian Iris is a low maintenance plant which has roots that grow deep into the ground allowing it to tolerate a wide range of soil conditions. It prefers full sun but will also grow in part shade.  Its elegant violet blue blooms last only 1-2 days but the grass like foliage will stay green into the fall.  Siberian Iris attracts butterflies and is resistant to deer.  It works well as a specimen or in mass plantings.
