Siberian irises are outstanding perennial landscape plants. They are among the hardiest and easiest to grow of all perennials. Most bloom around the same time as peonies and many bloom in wonderful rich shades of blue and violet adding another color dimension to the peony plantings. Their broad sturdy grass like foliage adds a strong vertical element that remains attractive throughout the growing season.

Siberians are well adapted to a wide range of growing conditions in Zone 3-9, but like peonies, they need a cold dormant period to perform well. They grow and bloom well when planted in full sun. However, they will tolerate shade for less than half a day. Bloom will be directly proportional to the amount of sun received.
