About
Iris bucharica (also Bukhara iris, corn leaf iris and horned iris) is a species of flowering plant in the family Iridaceae. It is a bulbous herbaceous perennial, from temperate Asia, within Afghanistan, Tajikistan and Uzbekistan. It has long blue green leaves, many flowers in spring, in shades of yellow and white.
How to grow it
Iris bucharica is widely cultivated in temperate regions, and in the UK it has gained the Royal Horticultural Society's Award of Garden Merit.
It prefers free draining fertile soils which are neutral or slightly alkaline. The bulbs are planted in late summer or autumn, 5 cm (2.0 in) deep, in gravelly soils in full sun. Like others of its kind it needs 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.
Where it grows
Iris bucharica is native to temperate Central Asia. in north-eastern Afghanistan, Tajikistan and Uzbekistan around Bukhara. It is endemic to the Gissar Range, in the valleys of Surkhan-darya, Kafirnigan, Vakhsh, Ak-su and Kizyl-su rivers. It is found at 5,000–6,000 ft (1,500–1,800 m), in pebble beds and gravelly slopes of the lower mountain zone.
