It is a rhizomatous perennial, from the grassy mountainsides of Turkestan (now known as ). It has long green leaves, which are slightly purple at the base, long slender stem, the flowers are blue, ranging from sky-blue to lavender blue and blue purple. It also has orange or yellow beards. It is cultivated as an ornamental plant in temperate regions. ==Description== It has a stout,〔〔Christopher Brickell (Editor)〕〔British Iris Society (1997) 〕 or thick rhizome.〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 That produces many long, slender, fleshy secondary stolons, which travel through the ground searching for minerals to feed the plant.〔(【引用サイトリンク】url=http://irisbotanique.over-blog.com/categorie-0.html&usg=ALkJrhh70LNmXSsW7XWSPOAq9g9rjg4IpQ )〕〔(【引用サイトリンク】url=http://www.hillkeep.ca/bulbs%20iris.htm#Iris hoogiana )〕 They can be between long.〔 It also uses the stolons to form colonies of plants and spread over an area.〔 When the plant is dormant, (autumn and winter) it is very similar in form to ''Iris stolonifera.''〔 It has glaucous green,〔〔 or mid green,〔(【引用サイトリンク】url=http://www.backyardgardener.com/plantname/pda_fe37.html )〕 or bright green leaves.〔 That have a slight tinge of (or are stained,〔) purple at the base of the leaf.〔〔〔(【引用サイトリンク】url=http://www.greenfingers.com/gardenbase/plant/view.asp?id=39243 )〕 They are sword-shaped,〔〔(【引用サイトリンク】url=http://flowerlib.ru/books/item/f00/s00/z0000035/st026.shtml )〕 or ensate,〔 and slightly curved.〔〔 They can grow up to between long,〔〔〔 and between 1–2 cm wide.〔〔〔 The leaves begin to fade and die after, the plant has flowered.〔 It has stems that can grow up to between tall.〔(【引用サイトリンク】url=http://apps.rhs.org.uk/agm/Award3.asp?ID=9271 )〕 They are normally taller than the foliage,〔 and can also have a slight purple tinge.〔 The stem has green spathes or bracts (leaves of the flower bud),〔〔 that are long and 2 cm wide.〔 They have a membranous margin, which is tinged with purple,〔 or red.〔 The unbranched,〔 stems hold 2 or 3 terminal (top of stem) flowers,〔〔〔 blooming late spring,〔〔 or early summer,〔〔 between April and May,〔 or between May and June.〔〔 In the United States, it flowers in mid to southern states between early April to early May and it also flowers in mid to northern states between late April to early June.〔Allan M. Armitage 〕 The scented flowers,〔〔 are in diameter.〔〔〔 They come in shades of blue,〔〔(【引用サイトリンク】url=http://www.pacificbulbsociety.org/pbswiki/index.php/ArilIrises )〕 from sky-blue,〔 mid-blue,〔 grey-blue,〔〔〔Donald Wyman〕 lilac-blue,〔〔〔 lavender,〔〔〔 to blue-purple,〔 or lilac violet.〔 There is occasionally a white,〔〔〔 or very pale blue form. But they are not very vigorous and poorly lived.〔 It has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'.〔 The pendant shaped falls are long,〔 and 3 cm wide.〔 They are wide on the haft (the bend of the petal), and then becomes thinner along the blade (the tip of the petal).〔〔〔 They have a dense, orange,〔〔〔 golden yellow,〔〔〔 or yellow beard.〔〔〔 The beard is longer than ''Iris korolkowii's'' beard.〔 The obovate shaped,〔 standards are long,.〔〔 They widen gradually to from haft to a rounded apex.〔〔〔 It has a 2.5 cm long perianth tube,〔〔〔 which is green with a purple tinge.〔〔 It has short pedicels (flower stalks),〔〔〔 and oblong shaped styles,〔 which are 2.5 cm long,〔 and similar in colour to the flower petals.〔 It has semi-ovate,〔 or triangular crests,〔 and long anthers, with white,〔 or cream coloured pollen.〔 It has an oblong, 2.5 cm long ovary.〔 After the iris has flowered, in May,〔 it produces a long and narrow seed capsule,〔〔〔 which is pointed at the tip.〔〔〔 It dehisced (splits open) laterally (side to side).〔 Inside are pyriform (pear shaped), brown seeds.〔〔 They are rugulose and have a white aril (appendage).〔〔 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 hoogiana」の詳細全文を読む スポンサード リンク
