Iris siberica Linné synonyms: Iris praestans lamarck; Iris angustifolia Gilberti; Iris stricta Moench; Iris maritima Miller; Iris atracoerulea Lynch; Iris erirhiza Pospichal; Iris acuta Willdenow; Iris trigonocarpa A. Br.; Iris triflora Redouté.

As one would assume, due to the many synonyms for Iris siberica, it has a very wide and varied distribution. It is found from northern Europe in the East to Siberia in the West and into parts of Asia. Similar to I. sanguinea, it is distinguished by having dried bud bracts at bloom time, generally 3-5 blossoms, narrower falls and an inflorescence longer than the leaves. The seed capsule is rounder and not more than twice as long as wide. Height varies between 24"/60 cm and 48"/120 cm. Chromosome count 2n=28. Flowers are mid to mid-dark blue with a white signal veined in blue. The throat is gold-yellow, also veined in dark blue. Standards are upright, falls are narrow at the hafts widening to a spatulate and pendant end.
