Iris heweri is a plant species in the genus Iris that is native to Afghanistan. It is a rhizomatous perennial with tall, green curved leaves and tall slender stems. Its flowers are purple blue or violet-blue with a white and purple or lilac beard. This plant is cultivated as an ornamental in temperate regions and is similar to Iris falcifolia but has a looser rhizome system and different leaves. It has a small and slender rhizome with several stolons and 4-7 grey-green or green falcate leaves. The stem can grow up to 30 cm tall and has spathes and 1-3 terminal flowers. The flowers are 5 cm in diameter and have 2 pairs of petals, with the outer petals known as "falls" and the inner petals known as "standards". After flowering, it produces a seed capsule with dark brown seeds inside. This plant has a chromosome count of 2n = 22 and was named after Professor Thomas Frederick Hewer, a pathologist and plant collector. It is found in alpine meadows, screes, and grassy and sandy slopes in Afghanistan at an altitude of 1,100-2,200 meters
