''Iris vartanii'' is a species in the genus ''Iris''. It is also part of the sub-genus ''Hermodactyloides'' and Section ''Reticulatae''. It is a bulbous perennial. It was once though to be part of the ''Iris'' sub-genus ''Xiphium''. It is sometimes referred to as 'Vartanni Iris', 〔 Moira McCrossan, Hugh Taylor 〕 or 'Iris vartani'. It was first described in 1885 in Gardeners' Chronicle, and an illustration (No.6942) was published in Curtis's Botanical Magazine two years later.〔 Walters, Stuart Max (Editor)〕 It was named by Sir Michael Foster after Dr. Vartan from Nazareth. ==Habit== It has four leaves that are un-equalsided and up to 20cm tall (when in flower), but that increases to nearly 40cm later. It flowers between October and December.〔 Lynch, Richard〕 The flowers are greyish lilac-white, (or slaty blue 〔) with falls having dark blue veins. The flowers smell of almonds.〔 Due to its early flowering (during winter), the leaves can be damaged (by snow and ice) so much that the plant does not form healthy bulbs for the next year. So it is best grown like other species of iris in an alpine house or bulb frame. It is hardy to USDA Zone 3.〔 Like other members of the reticulata group (including Iris danfordiae), it has the habit of the main bulb splitting into many bulblets, that can take many years (between 2-3 years) to reach flowering size again.〔 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 vartanii」の詳細全文を読む スポンサード リンク
