Iris typhifolia
Iris typhifolia is a species in the genus Iris, also the subgenus Limniris and in the series Sibiricae. It is a rhizomatous herbaceous perennial, from China. It has slender, twisted leaves, deep green slender hollow stem and 2 violet-blue flowers. It is cultivated as an ornamental plant in temperate regions.
Iris typhifolia should be grown in moist, slightly acidic soil (the pH level should be less than 7.8) with plenty of organic matter. It is tolerant of sandy or clay soils, as long as plenty of organic matter is added before planting.
It prefers positions in full sun but can tolerate part shade (with some hours of sunlight). Although, in non-temperate areas (hot arid areas), they need shade, mulching and extra watering to survive. The iris needs moisture during the growing season (in spring and early summer) to create best blooms. But they don't grow in the water. Although they will tolerate occasional flooding.
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Handling the plant may cause a skin irritation or an allergic reaction.
