Iris cycloglossa: The Afghan Iris

Iris cycloglossa, commonly known as the Afghan iris, belongs to the Iridaceae family of plants. Its name “cycloglossa” derives from the Greek words for “tongues arranged in a circle,” alluding to the unique arrangement of its petals. Native to Afghanistan, this iris species was first described by Per Erland Berg Wendelbo (1927-1981), a Norwegian botanist, in the publication ‘Biologiske Skrifter‘ in 1959.

Iris cycloglossa is a hardy perennial that reaches a height of about 20 inches (50 cm). Its striking blue flowers bloom in spring, featuring lavender-blue petals with a distinctive white patch on the falls. The falls also boast a raised yellow ridge, adding an extra touch of elegance to the blooms. The flowers are not only visually appealing but also emit a delightful fragrance. Iris cycloglossa showcases its natural beauty in May and June when it bursts into bloom. Complementing the enchanting flowers are the shiny, grey-green leaves that grow up to 30 cm long, enhancing the plant’s overall ornamental value.
