It has thick, branching, dark brown rhizomes, that are 1.5–2 cm in diameter.[2] This branching habit creates dense clumps of plants.[3][4] [5]

It has greyish green, linear, smooth, sword-shaped, leaves.[6] They can grow up to 25–50 cm (10–20 in) long and 6-13mm wide.[2][6]

It has erect, slightly inclined, unbranched stems, that can grow up to 50–76 cm (20–30 in) tall.[2][4][7]

The stems have lanceolate spathes (leaves of the flower bud), that are 5.5–8 cm (2–3 in) long.[2]

The stems hold between 3–5 terminal (top of stem) flowers, between June and July.[3][4][6] The fragrant flowers,[3][4][5] can be up 6–8 cm (2–3 in) in diameter,[6] and are very varied in colour. Varying between dark purple,[5] pale purple,[4][3][5] light lilac,[7] pale blue and off-white.[2]

It has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals, known as the 'standards'.[8] The narrow falls have an elliptical blade, measuring 20–25 mm long and 12–16 mm wide. With a bright yellow or orange central signal.[2][7]

The erect standards are lanceolate with yellow claws (section of petal close to the stem).[2]

It has style branch which have a yellow carinate (ridge).[2]

It has a 7-10mm long perianth tube, yellow anthers and winged ovary.[2]

After the iris has flowered, it produces an oblong-cylindrical, seed capsule, between August and September.[3][2][5] It has 6 pairs of converging, winged edges.[3][2][5] Inside the capsule, are light brown semi-circular seeds.[3][5]

It is written in Russian Cyrillic script as Ирис ложноненастоящий.[9]
