Iris sintenisii is a small, clump-forming rhizomatous perennial iris with grass-like leaves and violet-blue flowers, grown in rock gardens and troughs. The key to growing it is well-drained soil that stays moist in the growing season but never waterlogged.
Iris sintenisii is a species in the genus Iris, in the subgenus Limniris and in series Spuriae, with tall thin stems, violet-blue flowers and long grass-like leaves. It is a rhizomatous perennial plant, from grass meadows (including steppe) parts of Europe, Russia, and Turkey. It is cultivated as an ornamental plant in temperate regions.
It is hardy to between USDA Zone 5a (−28.8 °C (−20 °F)) to USDA Zone 9b (−3.8 °C (25 °F)). It is also in European Zone H2. It can tolerate temperatures as low as −18 °C. It is hardy in the UK, although within Russia, it is not hardy in St Petersburg, but thrives in the Botanical Garden of Stavropol.
It prefers to grow in well-drained soils, that do not dry out during the summer. The shallow roots do not like intense summer heat, which dries out the soil. They are tolerant of soils containing limestone. They can grow in neutral to alkaline soils (with a pH level of between 6.6 and 8.5).
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.
Iris sintenisii is native to temperate regions of Asia Minor, eastern Europe and south eastern Europe.
