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] HabitIt has a slim bulb (coloured cream) with a long thin neck. Below the bulb are tuberous roots that are white, thin and 6in long.[7] 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 downard-turned rich purple (or deep purple)[10] standards and creamy yellow (or pale yellow[10]) falls.[6] The flowers do not produce any scent.[2] After flowering, it produces seeds, but there is no aril (coating) on the seed.[7] The seeds are cube-shaped.[7] It has deeply channeled[7] mid-green leaves which have a silver edge.[6] Which start growing in early December. By March, they have turned grey near the base, and mid-green at the tops.[8] They reach between 4-8mm wide and grow up to 18 cm long.[10] The leaves when mature hide the stem.[8] The plant reaches a total height of approximately 10–15 cm tall when in bloom.[9] Best grown in the uk, in an alpine house or bulb frame.[6] NativeFound 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,[8] near Kopet Dag mountain range.[10] Which also includes the former Russian state of Turkmenistan.[9][11] References1. ^{{cite web|title=Iris fosteriana Aitch. & Baker | url=http://www.theplantlist.org/tpl/record/kew-321843| publisher=www.theplantlist.org|accessdate=19 August 2014}} 2. ^1 2 3 4 5 {{cite web|first=Michael|last=Foster|year=1945| title=Bulbous Irises| pages=44–45| publisher=Forgotten Books|url=http://www.forgottenbooks.com/readbook_text/Bulbous_Irises_1000909387/49|accessdate=20 August 2014}} 3. ^Ray Desmond (25 Feb 1994) {{Google books|thmPzIltAV8C|Dictionary Of British And Irish Botantists And Horticulturalists Including plant collectors, flower painters and garden designers|page=258}} 4. ^{{cite web| title=Iris fosteriana |url=http://www.ipni.org/ipni/idPlantNameSearch.do?id=438612-1 |publisher=apps.kew.org |accessdate=19 August 2014}} 5. ^{{cite web|title=Iris fosteriana|url=https://www.rhs.org.uk/Plants/9254/Iris-fosteriana/Details |publisher=www.rhs.org.uk|accessdate=19 August 2014}} 6. ^1 2 {{Cite book |year=1996 |editor-last=Brickell |editor-first=Christopher |title=RHS Encyclopedia of Garden Plants |page=522 |publication-place=London |publisher=Dorling Kindersley |isbn=978-0-7513-0436-7 }} 7. ^{{cite book |last1=Cassidy |first1=G.E.| last2=Linnegar |first2=S.|date=1987 |edition=Revised |title= Growing Irises|url= |location=Bromley |publisher=Christopher Helm |pages=145–146 |isbn=0-88192-089-4 }} 8. ^1 2 3 4 5 {{cite web|title=Juno Irises A-I| date=30 March 2014|url=http://www.pacificbulbsociety.org/pbswiki/index.php/JunoIrises| publisher=www.pacificbulbsociety.org|accessdate=20 August 2014}} 9. ^1 2 3 4 {{cite web|title=Iris fosteriana |year=2011|url=http://encyclopaedia.alpinegardensociety.net/plants/Iris/fosteriana/publisher=encyclopaedia.alpinegardensociety.net |accessdate=20 August 2014}} 10. ^{{cite web|first=Marijn |last=van den Brink|title=Iran, Koppe Dag mountains| date=April–May 2009| url=http://photos.v-d-brink.eu/Flora-and-Fauna/Asia/Iran-Koppe-Dag-mountains/i-2NpdLtk |publisher=photos.v-d-brink.eu|accessdate=20 August 2014}} 11. ^Czerepanov, S.
