''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'〔(【引用サイトリンク】 url=http://www.digdropdone.com/bulbs/iris-iris-bucharica.html )〕〔(【引用サイトリンク】 url=http://www.hgtvgardens.com/flowers-and-plants/corn-leaf-iris-iris-bucharica )〕 or 'Horned iris'.〔〔(【引用サイトリンク】 url=http://www.yonemura.co.jp/zukan-f/naiyou/iris-buch0.htm )〕 It is pronounced 'bukh-AR-ee-kuh' and named after the city of 'Bukhara' in Uzbekistan, Russia.〔John Weathers〕 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'.〔(【引用サイトリンク】url=http://www.wiki.irises.org/bin/view/Spec/SpecBucharica )〕 It was then published as ''Iros bucharica'' in The Gardeners' Chronicle by Foster in 1902.〔(【引用サイトリンク】 url=http://www.ipni.org/ipni/idPlantNameSearch.do?id=438440-1 )〕 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. This plant has gained the Royal Horticultural Society's Award of Garden Merit.〔(【引用サイトリンク】 url=http://apps.rhs.org.uk/plantselector/plant?plantid=1034 )〕〔(【引用サイトリンク】 url=http://www.rhs.org.uk/Plants/9218/Iris-bucharica-Foster/Details )〕 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.〔 ''Iris orchioides'' hybridizes freely with 'Iris bucharica' to create a large golden flowered hybrid.〔 It is deer resistant.〔 ==Habit== Iris bucharica has a yellowish white bulb〔 (about 2 cm in diameter) with thin fleshy roots.〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 It grows up to between 20 and 40 cm (12-16 inches) high.〔〔〔〔〔 It has lanceolate (lance-like) leaves,〔 which are blue-green below and glossy green (on the reverse).〔〔 They reach up to 3.5 cm wide and grow up to 20 cm long.〔〔 The leaves are scattered up the flower stems.〔 Each stem produces up to 7 flowers in spring,〔〔 March〔 or April.〔〔 They bloom in order from the top of the stem, going downwards.〔 They are not scented.〔 The perianth tube is about 4.5–5 cm long.〔〔 The flowers have white (or creamy white)〔 standards with yellow falls.〔〔〔 The falls sometimes have brown markings and a deep yellow crest.〔〔 The flowers are about 2.5 inches across.〔 Pure yellow forms are occasionally wrongly labelled as ''I. orchioides'' (a different species).〔(【引用サイトリンク】 url=http://www.pacificbulbsociety.org/pbswiki/index.php/JunoIrises )〕 It has semi-circular stigmas, with whitish anthers and pollen.〔 Iris bucharica, Iris orchioides and Iris warleyensis all have cubiform seeds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Iris bucharica」の詳細全文を読む スポンサード リンク
