Distribution
Cultivation
It is grown from tubers planted in the autumn. It grows best in full sun to partial shade, and requires well-drained soil. It can naturalise in grassy areas but grows well in rock gardens or containers.[8] It is a common ornamental garden plant, flowering in early spring. It is rather tender in the UK.[9]
Taxonomic history

After being split off from the genus Iris in the nineteenth century into a separate genus,[10] Hermodactylus, it has most recently been returned to the genus Iris,[11][12] following molecular studies at Kew.[13] According to the proposed molecular classification of irises of Tillie, Chase and Hall,[13] this species is now best seen as a member of the subgenus Hermodactyloides, the reticulate-bulbed bulbous irises.
