It is a bulbous perennial

It was described in 'Commentat. Soc. Phys.' to Caesareae Universitatis Mosquensis of 1808 by Georg Hoffman.[5]

It was once confused with iris orchioides, but iris caucasica is a smaller plant, with sessile flowers. Also it has leaves that have white margins.[6]

Iris caucasica is an accepted name by the RHS.[2]

Habit

It has between 1–4 flowers per stem, normally pale yellow or green and with winged falls.[7] The falls also have a yellow ridge.[8] The flowers are 5–15 cm (2–6 in) across.[7] It flowers in later spring.[9] It eventually reaches a height of 15 cm (flower and stem).[9] he flowers are not fragrant.[6]

It has grey green leaves,[8] which are ciliate[9] and that start growing at flowering time.[7] They reach up to 10–12 cm long and l-2 cm wide.[9] The leaves have a faint white margin.[10]

It has a brown ovoid bulb with fleshy roots.[6] It is similar to Iris persica.[3]

Native

Iris caucasica grows on limestone mountain slopes (at 1200-3500m above sea level)[9] in Turkey[8] and Armenia and Azerbaijan,[11] in the Caucasus mountains.[8] Bieberstein notes seeing it near Tbilisi in the South Caucasus.[3] It has also been found in Israel and Iran.[10]

Hybrids

In 1892, Michael Foster introduced a hybrid version 'Iris Caucasica Kharput'.[4] Which does not have winged falls.[7] It still has 4–5 flowers per stem, which are greenish-yellow. But they are generally larger than parent plant.[6]
