Iris narbutii is a species in the genus Iris, it is also in the subgenus of Scorpiris. It is a bulbous perennial. It is sometimes misspelt as 'Iris narbuti'.[2][3]

It was first published as 'Juno Narbutii' by Olga Fedtschenko in 'Izvestiya Imperatorskago Obscestva Ljubitelej Estestvoznanija, Antropologii i Etnografii, Sostojascago pri (Imperatorskom) Moskovskom Universitete' in 1902.[4] It was later published as 'Iris Narbutii' by Boris Fedtschenko in Bull. Jard. Bot. St. Petersb. Vol.V page157 in 1905.[5]

Iris narbutii is now an accepted name by the RHS.[6]

It is listed in 1995 in 'Vascular plants of Russia and adjacent states (the former USSR)' by Czerepanov, S. K.[7]

It may have been named after 'Narbuta Beg'(1774-1798), a grandson of 'Abd al-Karim' (Khanate of Kokand) of the Fergana Valley, Central Asia, where the iris was found.[8]

It can be seen growing in the 'Le Grand Clos Botanique Garden' in Bourgueil, France.[9]

It can be cultivated in pots,[10] or in well drained soils in sunshine (like other Juno irises).[11]

Habit

Iris narbutii has a brown bulb with papery tunic,[10] the bulb is approx. 2 centimetres (0.79 in) in diameter.[12] It has thickened roots,[5] which look similar to fat short pointed tubers.[13]

One of the shorter Juno irises, similar to Iris Lepthoriza,[10] only growing to a height of 5–10 cm (2.0–3.9 in).[5][11][14][15]

It blooms in early-mid spring,[12] flowering between January to April depending on the weather conditions.[5][10][11] It has 1 or 2 scentless flowers per bulb stem.[5][12][14]

The flowers come in a range of shades between greenish-yellow to pale violet.[10][11][14] The green-purple perianth tube is about 4–5 cm (1.6–2.0 in) long.[5][12] It has standards (3.5–5 cm or 1.4–2.0 in) that hang downwards.[11][15][16] It has falls that start upright, but then the blade bends downwards, with a dark violet blotch at the tip. They have a raised white crest surrounded by a yellow zone/area.[10][11][14][15][16] The yellow zone can sometimes have a dark purple ring around it.[12]

It has whitish pollen.[5]

The thin, channelled dark green leaves emerge before the flowers, they are 5–25 mm wide (close to the base of the plant).[5][11][12] They gradually narrow to an apex (falcate-like, lanceolate)[10] and have a very visible white edging/margin.[5]

Native

Iris narbutii is from Central Asia.[14][16] Originally found on the slopes of Syr-Darya river valley.[5][15]

It is found on the rocky, gravelly slopes of the mountains of western Tien Shan and southern Pamir Mountains.[12] Also seen near to Samarkand and Tashkent.[5]

Olga Fedtschenko had speculated that the plants from west Tien Shan, could be a separate species, due to their paler colour.[5]

In Chulbair Mountains, Uzbekistan, it is a threatened species and close to extinction.[10]

Known hybrids

In Russia, Vvedenskii had noted several natural hybrids including; J. narbutii x J maracandica (near Jizzak, Uzbekistan), J. narbutii x J. Orchioides and J. narbutii x J. subdecolorata (near Darbaza, Kazakhstan).[12]
