It was once though to be part of the Iris subgenus Xiphium.[3] It is sometimes referred to as 'Vartanni Iris',[4] or 'Iris vartani'.[5]

It was first described in 1885 in Gardeners' Chronicle, and an illustration (No.6942) was published in Curtis's Botanical Magazine two years later.[6] It was named by Sir Michael Foster after Dr. Kaloost Vartan from Nazareth.[7] Who discovered the iris while working in Palestine in the foothills around Nazareth, and sent the specimen to Foster for classification. It was originally described as brown in colour, presumably due to deterioration in transportation.

Habit

It has four leaves that are un-equalsided and up to 20 cm tall (when in flower), but that increases to nearly 40 cm later.[8]

It flowers between October and December.[9] The flowers are greyish lilac-white, (or slaty blue [8]) with falls having dark blue veins. The flowers smell of almonds.[6]

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.[10] So it is best grown like other species of iris in an alpine house or bulb frame. It is hardy to USDA Zone 3.[6]

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.[7]

Distribution

It was originally found near the city of Nazareth in Israel.[9] and it was also found in Jordan and Syria.[11] On rocky hillsides.[12] It is found in Golan, Galilee, Mount Carmel, Samarian desert and Judean mountains, various regions of Levantine.[13] But according to Dr Dawud Al-Eisawi's book Field Guide to Wild Flowers of Jordan (1998), it is now thought to be extinct in Jordan.[4][14]

Cultivar

I. vartanii White pearl First found in 1910 in Beersheba and Hebron,[9] it was originally thought to be a white form of I. histrioides. On 21 December 1912, it was described in 'The Garden' magazine of the Royal Horticultural Society, now as a white form of I. vartanii. Then in 1913, it gained Award of Merit by the RHS.[15]

It is sometimes referred to as Iris vartanii var. alba.[9]
