Iris bucharica is a species in the genus Iris, it is also in the subgenus of Scorpiris. It is a bulbous perennial. It is also commonly known as 'Bukhara iris' or 'Corn Leaf Iris' or 'Horned iris'.
It was illustrated in the Curtis's Botanical Magazine, Tab. 7111 on 1 April 1890, and was incorrectly described by Baker as a specimen of 'Iris orchioides'. It was then published as Iros bucharica in The Gardeners' Chronicle by Foster in 1902. Michael Foster got the bulbs from the UK bulb merchant 'Van Tubergen' (also based in Harlem, Netherlands). It was also published in 'Flora and Sylva' in 1905.
It was introduced into the UK in 1902.
It is best cultivated in free draining fertile soils which are neutral or slightly alkaline, in full sun. The bulbs should be planted in late summer or in the autumn, but only about 5 cm deep (2-3 inches) It can grow in gravelly soils in full sun. They prefer to have a period of warmth and dryness during the summer, to prevent the fleshy roots from rotting away. This is normally after the foliage dies back in late June or early July.
It is widely cultivated in temperate regions. It is hardy to USDA Zones 5-9 or 4-8, or 4-9. But it can be grown in a pot in a greenhouse. Providing it is kept dry in summer and left out in the autumn rains.
It is thought to be fairly easy to grow and will increase (by bulblets), very quickly. This means it will naturalise quickly if growing conditions are favourable. Creating drifts in borders or rock gardens They should be lifted and divided every 3–4 years, to prevent over crowding.
It can be grown from seed as well, but this will take several years before the bulbs are big enough to produce flowers.
It is deer resistant.
with thin fleshy roots.
