It is a rhizomatous herbaceous perennial, from Asia, including north east India, Nepal, Tibet, Bhutan, Burma and in China. It has grey-green leaves, long and thin green stem and violet, to dark blue, to blue or reddish purple flowers. ==Description== ''Iris clarkei'' is unique among the members of the ''Iris sibiricae'' group, as it has a solid stem and not hollow.〔〔〔〔 It has a creeping habit that eventually forms a loose colony of plants.〔〔〔 The rhizomes are slender and cylindric in form and sometimes clothed with the fibrous remains of the leaves from last season.〔〔 It has grey-green leaves, that are glossy or glaucous on one side and dull on the other side.〔〔〔 They are also linear, sword-shaped (lanceolate) and can grow to between 30–60 cm (10–24 in) long and between 0.8–2 cm (1/3-1/2 in) wide.〔〔〔〔〔 The slender leaves begin to droop, the larger they get.〔 It has a green, cylindrical, flowering stem or scape which is about 5mm wide, and can grow up to between 45–60 cm (17-24 inches) long,〔〔〔〔〔〔〔〔〔 or very rarely 90 cm (3 ft) long.〔〔 It has between 2-3 branches, with normally 2 flowers at the end of the branches.〔〔〔〔〔〔〔 It blooms between late spring and early summer,〔〔 between May and July.〔〔〔 The flowers appear well above the leaves.〔 The flowers come in a range of shades of blue. From violet,〔〔〔〔〔 to dark blue,〔〔 to blue,〔〔〔〔 to a reddish purple colour.〔〔〔〔 The flowers are between 5–10 cm (2–4 in) in diameter.〔〔〔 It has 2 pairs of petals, 3 large sepals (outer petals) known as the falls and 3 - 4 smaller petals known as the standards. The falls are larger, drooping, pendant shaped (in botany terms - obovate) and have a large white/yellow signal patch with violet or dark blue veining.〔〔〔〔〔〔〔〔〔〔 The standards are smaller, narrower (oblanceolate), plain coloured, upright, and usually horizontal.〔〔〔〔〔〔 It has a green perianth tube (about 5 cm long and 1 cm wide), slender green pedicel (about 2-3.5 cm long), milky white anther and blue style branches (about 4.5 cm long).〔〔 Between August and September (after flowering), it has an oblong shaped (with 3-angled sides and 6 ridges/veins) seed capsule, which is 3.5–5 cm (1-2 inch) long and 1.2-2.5 cm (0.5-1 inch) wide.〔〔 Inside, are dark brown, semi-circular, flat, disc-like seeds.〔〔〔 The seeds are similar in form to ''Iris delavayi'' 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 clarkei」の詳細全文を読む スポンサード リンク
