Iris tigridia is a species in the genus Iris, it is also in the subgenus of Iris and in the Pseudoregelia section. It is a rhizomatous perennial, from Kazakhstan, Russia, Mongolia and China. It has dark green or greyish green, grass-like leaves, a short slender stem and a single (or rarely 2) flowers that are either violet, dark blue, blue-purple, dark purple, mauve, lilac, lavender, or light purple. It is cultivated as an ornamental plant in temperate regions.
It has small compact rhizomes. Which are brown, yellow or white, fibrous. Underneath the rhizome are numerous fleshy, secondary roots, which are between 3 – 4 mm wide. On top of the rhizome are the dense, brown, or dark brown, fibrous remains of last seasons leaves. It creates small tufted plants.
It has dark green, or greyish green leaves, that can grow up to between 5–30 cm (2–12 in) long, and between 1.5 and 6 mm wide. At the time of flowering, they are 5–13 cm (2–5 in) long, and between 1.5 and 2 mm wide. They then elongate to the final height of up to 30 cm tall. They are grass-like, they can be erect and linear, or slightly curved. They do not have a midvein, but have an acuminate apex (pointed) tip. This form separates them from Iris potaninii. In mild temperate areas, they are evergreen (lasting through the winter).
It has a slender stem, that can grow up to between 3–15 cm (1–6 in) tall. Sometimes, the stem seems to only just appear above ground.
The stem has 2, yellow-green, (scarious) membranous, spathes (leaves of the flower bud). They are lanceolate and between 3–4 cm (1–2 in) long, with a pointed tip.
The stems hold 1, (or rarely 2,) terminal (top of stem) flowers, blooming between April and May, normally in May.
The flowers are 3.5–5 cm (1–2 in) in diameter, come in shades of violet, dark blue, blue-purple, dark purple, mauve, lilac, lavender, or light purple. The flowers have darker spots, veining or mottling.
Like other irises, 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'. The falls are obovate, and 3–4 cm (1–2 in) long, and 1-1.5 cm wide. It has in the centre of the petal, is a white patch, and a beard, with blue-white, or white hairs, tipped with yellow, or yellow hairs. The erect, or tilting outwards, standards are oblanceolate, and 2.5–3 cm (1–1 in) long and 0.4-0.7 cm wide. They are darker shade than the falls.
