Siberian Irises bloom late spring to early summer. The beardless iris flowers come in a rainbow of purples, off purples, yellows, and whites, with both single and double flower forms. Once established, Siberian Irises are totally care free.

I have a stand of Siberians that came with my house. Last fall I divided and replanted them. Initially it looked like I'd lost most of them, but they came back well and have filled in the section. They did not bloom this year, but I'm pleased with their progress.
