It was named after Michael Foster (a known British Iris expert) by Dr Aitchison, and found in Pendjeh, Turkmenistan. [2] [3]

First described in transactions of the Linnean Society of London in April 1888 and then published by John Gilbert Baker in Botanical Magazine in 1892. [4]

Iris fosteriana is an accepted name by the RHS. [5]

It has many similarities with other iris species in the Xiphium. [2]

Habit

It has a slim bulb (coloured cream) with a long thin neck. Below the bulb are tuberous roots that are white, thin and 6in long. [6] The fragile roots mean that the bulb does not take transplanting very well. [2]

In Spring, (March in the UK [2] ) it has 1 or 2 long tubed flowers that are 4–5 cm (1.5 or 2in) wide with downward-turned rich purple (or deep purple) [7] standards and creamy yellow (or pale yellow [7] ) falls. [8] The flowers do not produce any scent. [2] After flowering, it produces seeds, but there is no aril (coating) on the seed. [6] The seeds are cube-shaped. [9]

It has deeply channeled [6] mid-green leaves which have a silver edge. [8] Which start growing in early December. By March, they have turned grey near the base, and mid-green at the tops. [6] They reach between 4-8mm wide and grow up to 18 cm long. [7] The leaves when mature hide the stem. [6]

The plant reaches a total height of approximately 10–15 cm tall when in bloom. [7]

Best grown in the uk, in an alpine house or bulb frame. [8]

Native

Found in the sandy soils of Gulran, Afghanistan, at an altitude of about 4,000 feet. [2] It is also found on the dry steppes (750-2000m above sea level) of North East Iran, [6] near Kopet Dag mountain range. [10] Which also includes the former Russian state of Turkmenistan. [7] [11]
