Siberian iris or Siberian flag, is a rhizomatous perennial with long leaves, tall stems, holding numerous violet-blue to blue, and occasionally white flowers. These seeds are for the rare white coloured flowers.

Iris sibirica is native to Europe and Central Asia, and has been naturalized in various states of North America including in Canada Ontario, and in the USA Connecticut, Maine, Massachusetts, New York, Pennsylvania, Virginia and California. Siberian Iris is considered vulnerable or rare in many countries. 

It is found in nature growing in damp woodlands, wet meadows, grasslands or pastures, along lakes, and beside streams, and ditches beside roadsides. They can also be used within a Herbaceous border. The iris can also be used in mixed plantings with grasses and other perennials to create naturalized gardens and meadows. They also do well at waterside locations beside pools, ponds or streams, and are ideal bog garden plants. 

It prefers positions in full sun in most areas, but can tolerate part shade. Especially in very hot, arid regions, they will need some shade.

They are sturdy plants and do not need to be staked.

The iris will tolerate temperatures down to -20 °C (-4 °F). It is hardy to USDA Zone 2–8, and if the plants are mulched in winter they can withstand zone 1.
