Iris potaninii is a species in the genus Iris, it is also in the subgenus of Iris and in the Psammiris section. It is a rhizomatous perennial, from Siberia in Russia, Mongolia and China. It is a dwarf plant, having either subterranean or very small stems, long thin leaves and yellow, or dark violet to purplish blue flowers. It is cultivated as an ornamental plant in temperate regions.
Similar in form to Iris tigridia (within Pseudoregalia section) and Iris bloudowii (another Psammiris section iris), but differs from bloudowii, in having an ob-conical, not prostrate rhizome. It differs from tigridia by having old leaf fibres on the rhizome. It also differs from Iris tigridia in leaf form, Iris potaninii has rounded ended leaves, which do not end in a point.
It has thick, short and tough rhizomes. Under the rhizomes, are thick, fleshy and yellowish, secondary roots. On top of the rhizome, are the curled, fibrous remains of last seasons leaves.
It has linear basal (growing from the base) leaves, which are not pointed at the ends (or obtuse). They can grow up to between 4–18 cm (2–7 in) long and 0.2-0.4 cm wide, at blooming time. The leaves then lengthen, and by the time the iris has seed capsules, they are between 20 cm (8 in) long and 0.3-0.4 cm wide.
It is a dwarf plant, having either subterranean, or very small stems or pedicels. They can reach up to between 5–10 cm (2–4 in) long.
The pedicel (or dwarf stem) has 2 narrow, lanceolate (or oblong-lanceolate,) and (scarious) membranous spathes or bracts (leaves of the flower bud). They are 4–4.5 cm (2–2 in) long and 0.6 cm wide.
The stem (or pedicel) holds 1 terminal (top of stem) flower, between April to May (in Russia), or May to June.
The flowers are 3.5–5 cm (1–2 in) in diameter, come in yellow, or dark violet to purplish blue shades.
