Iris spuria subsp. carthaliniae is a species in the genus Iris, it is also in the subgenus of Limniris and in the series Spuriae. It is a subspecies of Iris spuria, a rhizomatous perennial plant, from the Caucasus region, it is a tall iris with sky blue or white flowers. It was originally described by Fomin, as a separate species before Brian Mathew in 1981, added it to Iris spuria as one of its many subspecies. It is cultivated as an ornamental plant in temperate regions.
It has a thick, creeping, horizontal, branched rhizome. The creeping habit creates large clumps of plants. It has linear, flat, lanceolate, lacuminate (ending in a point), leaves. These can grow up to between 70–95 cm (28–37 in) long and 10–18 mm wide. The leaves are generally either equal to the flowering stem or longer than it.
It has a sightly compressed, stem (or peduncle), that grows up to between 50–100 cm (20–39 in) long. It has small, green, leathery ovate or lanceolate, spathes (leaves of the flower bud). They have a white membranous edging. The stems hold between 3-5 terminal (top of stem) flowers, on unequal pedicels, in summer, between June and July, or between May and June (in the US and Britain).
The lightly fragranced flowers, are can be up 7–9 cm (3–4 in) in diameter, and come in shades of sky blue, light blue, or white. 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 long and narrow falls have a reflexed, elliptical, almost round blade, with a yellow central stripe or blaze, which leads along the long thin claw (section closest to the stem). They also have dark veining. They are 5–7.5 cm (2–3 in) long. The erect, upright standards, are slightly ruffled, oblanceolate and single coloured. Over the falls, are the style branches, which are slightly shorter than the claw of falls. They have a 2 lobed end (or notched end), and a defined crest or ridge leading to the stem. They have a cylindric perianth tube (which about two-fifths the length of ovary), light purple anthers and a cylindrical ovary with 6 ribs.
