Iris setosa is a species in the genus Iris, it is also in the subgenus of Limniris and in the Iris series Tripetalae. It is a rhizomatous perennial from a wide range across the Arctic sea, including Alaska, Maine, Canada (including British Columbia, Newfoundland, Quebec and Yukon), Russia (including Siberia), northeastern Asia, China, Korea and southwards to Japan. It has tall branching stems, mid green leaves and violet, purple-blue, violet-blue, blue, to lavender flowers. There are also pink and white forms. It is one of the three Iris species in the Iris flower data set outlined by Ronald Fisher in his 1936 paper "The use of multiple measurements in taxonomic problems" as an example of linear discriminant analysis.
Iris setosa is similar in form to a miniature Japanese Iris, or a dwarf version of iris sibirica but a shorter lived version.
The shallowly rooted, large, branching rhizomes spread over time to create large clumps. The rhizomes are grey-brown, thick, and are covered with old (maroon-brown) fibrous leaf remains (of last seasons leaves).
It has branched stems, which are very variable in height. Ranging from 10 cm (5inches) up to 1 m (3 ft) tall. The larger plants can grow beyond the height of the leaves. The roundish stems are between 1.5–9 cm in diameter with 1 to 3 branches.
It has mid-green leaves, which are grass-like, and lanceolate (sword-shaped). They have a purplish tinged base and the leaves can measure 30–60 cm (12–24 in)long by 0.8-2.5 cm wide.
It has 3-4 flowers per stem (between 6 and 13 for the whole plant, in groups of 3) and it blooms between June and July.
