About

Iris orjenii, the Orjen iris, is a rare species of iris found in Montenegro and Bosnia and Herzegovina on the karst landscape of Orjen mountain. It grows in the wild on grassy slopes at 1,500 to 1,700 m (4,900 to 5,600 ft), in sunny or semi-shaded locations within Bosnian Pine communities. It is a member of the subgenus Iris, meaning that it is a bearded iris, and grows from a rhizome.

Where it grows

Iris orjenii is exclusively confined to Orjen, the highest mountain of the coastal Dinaric Alps, towering over the Bay of Kotor in southwestern Montenegro. Heavy glaciated during the Pleistocene period, glaciokarstic morphology dominates the higher portions of the mountain. Outstanding for intense precipitation averaging 5000 mm/a (maxima >8000 mm/a), Mount Orjen has by far the highest amount of rainfall in the Mediterranean and also one of the highest in Europe.
