Siberian Iris (Iris sibirica)
Description
Iris sibirica, commonly known as Siberian iris or Siberian flag, is a species in the genus Iris. It is a rhizomatous herbaceous perennial, from Europe (including France, Italy, Switzerland, Austria, Czechoslovakia, Germany, Hungary, Poland, Romania, Bulgaria, Former Yugoslavia, Belarus, Estonia, Latvia, Lithuania, Moldova, Ukraine and northern Turkey) and Central Asia (including Armenia, Azerbaijan and Siberia). It has long green grass-like leaves, tall stem, 2-5 violet-blue, to blue, and occasionally white flowers. It is cultivated as an ornamental plant in temperate regions.Iris sibirica was often confused with Iris sanguinea, another blue flowering Asian iris.But sanguinea has unbranched stems, while sibirica has branched stems.It has creeping rhizome (approximately 0.9-1.2 cm (0-0 in) diameter), forming a dense clumping plant.rhizomes are covered with the brown remnants of old leaves, from previous seasons.It has green grass-like leaves, which are ribbed and can sometimes have a pink tinge at the base of the leaf.They can grow to between 25-80 cm (10-31 in) long and 0.4-0.6 cm (0-0 in) wide, normally shorter than the flowering stems] In Autumn, the foliage turns yellow and then dies back (in winter), to re-emerge in the spring.It has a hollow, slender, 1-3 branched stem, that grows up to between 50-120 cm (20-47 in) long. The stems bear 2-5 (normally three) flowers, at the terminal ends between late spring and early summer, between May and June
