About

Iris pumila, sometimes known as pygmy iris or dwarf iris, probably originated as a natural hybrid between Iris pseudopumila Boissier & Heldreich and I. attica Tineo. It ranges from Austria through eastern Europe and the Balkans, in Eurasian steppe in Ukraine, southern Russia into southern Siberia and northern Kazakhstan, and the Caucasus into Turkey.

Iris pumila is distinguished by single blooms held 10–20 cm above ground level on a lengthened perianth tube, with the ovary almost resting on the rhizome on a very short stem. The flower is protected by two spathes, both of which are round in cross-section. Flower color is variable: yellow and purple or violet are the most common, but blue, cream, white, and blended colors are also frequently found. Most forms have a darker spot on the falls.
