It was once thought to be a form of ''[[Iris tenuifolia]]''.<ref name=cassidy/> Especially in China.<ref name=efloras/>

It has a slender, fibrous, knobbly or gnarled, brown-black rhizome.<ref name=efloras/><ref name=alpine/><ref name=atlas/><ref name=irisbotanique/><ref name=ussrflora>{{cite web |first=V.L. |last=Komarov |year=1935 |title=Akademiya Nauk SSSR (FLORA of the U.S.S.R.)

===Biochemistry===
In 2008, a study was carried out on the [[anatomical]] structure of the leaf and drought resistance of 4 different species of Iris (''[[Iris songarica]]'', ''[[Iris potaninii]]'', ''Iris loczyi'' and ''[[Iris lactea]]'') from [[Qinghai]], China. It showed that all the species were strongly adaptable to drought conditions.<ref>{{cite journal |last=Wang |first=Jun |last2=Gao |first2=Yi-ke |date=May 2008 |title=Study on the Relationship between Leaf Anatomical Structure and Drought Resistance of Four Species of Iris |url=http://en.cnki.com.cn/Article_en/CJFDTOTAL-HLJN200805040.htm |journal=Heilongjiang Agricultural Sciences |publisher=Landscape Architecture College of Beijing Forestry University, Beijing |volume= |issue= |pages= |doi= |accessdate=22 January 2015}}</ref>

It is [[Hardiness (plants)|hardy]] in [[Ashgabat]] and [[Tashkent]] in Russia.<ref name=onego/> It is tolerant of a wide range of temperatures.<ref name=irisbotanique/>

===Propagation===
It can be propagated by [[Division (horticulture)|division]] or by seed growing. But the seeds need to be [[Scarification (botany)|scarified]] and the seedlings need a constant temperature of 25C°.<ref name=irisbotanique/>

==Uses==
In China, it is forbidden to export plants or seeds. The reason is not known, but may be due to the medicinal usage of the plants.<ref name=irisbotanique/>
