Iris Siberian Caesar's Brother

Iris Siberian Caesar’s Brother

Siberian Iris are very hardy (zone 3). This one is deep purple and blooms in early June here in Wisconsin. It gets about 3 feet tall and can form large clumps up to 3 feet across. When the clumps get large enough that they start dying out in the middle just do some transplants. They are very tough and can take most conditions including poor dry soil and even boggy conditions, but will do best in moist soil and full sun.  Siberian Iris attracts butterflies and they are not favored by deer and rabbits.  There are no bugs or disease to worry about with these plants and they remain attractive well into fall and winter.  Just cut them down in spring.
