)) Iris grossheimii is a species in the genus Iris, it is also in the subgenus of Iris and in the Oncocyclus section. It is a rhizomatous perennial, from the Caucasus mountains of Georgia, Armenia and Azerbaijan.
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.[2] It has a chromosome count: 2n=20,[3][4] it was counted in 1977,[5] (published in 1980), by Avishai & Zohary.[6]
It is occasionally misspelt with one 'i' at the end,[7] and as Iris grossheimiana (mainly in Russia).[8][9]
The Latin specific epithet grossheimii refers to Alexander Grossheim (1888-1948, who was a Ukrainian botanist).
It was first described by Yury Nikolaevich Voronov (or Woronow) and then published by Alexander Grossheim in Fl. Kavkaza (Flora of the Caucasus) Vol.1 on page 255 in 1928.[1][10][11]
It is thought to be a hybrid cross between Iris lineolata and Iria lycotis.[3][4][12]
'Iris grossheimii' is listed in the Catalogue of Life,[13] and it was verified by United States Department of Agriculture and the Agricultural Research Service on 4 April 2003, then changed on 11 December 2014.[11]
It is native to temperate Asia.[11]
It is an endemic of the Caucasus,Cite error: A <ref> tag is missing the closing </ref> (see the help page).
In general, Oncocyclus Irises need minimal summer rainfall and dry winters. In temperate areas (such as the Europe and America) they are only suitable for growing by specialist iris growers, within a bulb frame or greenhouse.[14]
Irises can generally be propagated by division,[15] or by seed growing. Irises generally require a period of cold, then a period of warmth and heat, also they need some moisture. Some seeds need stratification, (the cold treatment), which can be carried out indoors or outdoors. Seedlings are generally potted on (or transplanted) when they have 3 leaves.[16]
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.[17]
