Description

Japanese Roof Iris (Iris tectorum) is a rhizomatous perennial iris species with attractive clusters of wide fan-like foliage. It is native of China and Korea, with lavender-blue, bluish-violet, purple-blue, blue-lilac or sky blue flowers. Although flowers are attractive, this plant is grown just as much for its foliage. It prefers to grow in rich, well-drained, forest soil in part shade. This plant will grow in thin soils on top of rock outcroppings provided that moisture is available; Iris tectorum is commonly called 'roof iris' because it was grown in the thatch of Chinese and Japanese houses. Mostly used in Kansas gardens as an accent or curiosity plant.
