Iris spuria subsp. maritima is a species of the genus Iris, part of a subgenus series known as Iris subg. Limniris and in the series Iris ser. Spuriae. It is a subspecies of Iris spuria, a beardless, rhizomatous perennial plant, from coastal regions Europe and north Africa with deep blue-violet flowers.
It is cultivated as an ornamental plant in temperate regions.
It has a rhizome, which is undescribed.
It has basal leaves, that can be described as evergreen (staying on the plant even during very cold winters). They are between 6mm to 2cm wide. They can grow as tall as the flowering stem at blooming time, but they then can grow taller after blooming period is over.
It has a stem that grows between 20–70 cm (8–28 in) tall.
The stem has several green, narrow and tapering spathes (leaves of the flower bud). They entirely cover the stem. The leaves are generally up to 8 cm long, and longer than the internodes.
The stems hold 2-4 terminal (top of stem) flowers, between Spring and Summer, between April and July.
It has scented, flowers that come in shades of blue-violet, purple, violet, or deep blue.
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 have a deflexed, rounded blade, 3–8 cm (1–3 in) long, with a yellow, cream or white centre that is heavily veined with purple or blue-violet. Behind the blade, it has a longer law (part of the petal closest to the stem) with a greenish stripe.
Unlike other spuria plants from Slovakia, the flowers have conspicuous distinctive veining on the blade, the enlarged end portions of the falls. The standards are erect, lanceolate, narrowly obovate and 3–6 cm (1–2 in) long.
It has a violet stigmata, that has 2 acute and erect lobes. It also has a ovary with narrow peak.
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. It has a chromosome count: 2n=38.
