About
Iris paradoxa is a species of flowering plant native to western Asia. It has large upright petals and smaller lower petals, which is unique amongst most iris forms. They come in various shades from white, lavender, mauve, medium purple, violet, dark purple to black. It has a black or purplish black beard on the lower petals. It comes from the region of Transcaucasia, and is found in the countries of Iran, Turkey, Armenia and in Azerbaijan.
How to grow it
I. paradoxa can be easily grown in an alpine house, or they can be placed in rock gardens, which should have a summer drought. They grow well in full sun with mildly acidic to mildly alkaline soils (of ph levels between 6.1–7.8). The flower and stem (if removed from the plant) may have a shelf life of two to three days. Irises can generally be propagated by division, or by seed growing.
I. paradoxa has been listed with Iris orientalis and Iris spuria subsp. musulmanica as halophyte (salt-tolerant) plants.
Safety
Like many other irises, most parts of the plant are poisonous (including rhizome and leaves), if mistakenly ingested, it can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.
Where it grows
Males of Xylocopa valga (a type of carpenter bee) have been observed pseudo-copulating on the reduced, velvety petals of the plant in Leriksky area, near Gosmaljan, Azerbaijan.
