A small rhizomatous perennial iris from the Elburz Mountains of Iran, with grass-like grey-green leaves and two large claret to dark purple flowers with a pale beard. It is rarely grown outside its native range, and it needs dry, sheltered conditions to survive.
Iris barnumiae subsp. demawendica (also spelled as demavendica) is a subspecies of Iris barnumiae. It is a rhizomatous perennial native to the Elburz Mountains in Iran. It was originally thought to be a separate species before going through various changes and being classed as a subspecies. It has erect, grey-green (grass-like) leaves and two large flowers, which come in shades from claret-red, burgundy, violet-blue, to dark purple, with a white or cream beard. It is rarely cultivated as an ornamental plant in temperate regions, due to the environmental conditions it prefers.
In 1903, a specimen of the species was given to Kew Botanical gardens, from Max Leichtlin, (from Baden-Baden, Germany).
Iris demawendica was listed for sale by Barr and Sons in 1904.
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), and if mistakenly ingested can cause stomach pains and vomiting. Also, handling the plant may cause skin irritation or an allergic reaction.
