Distribution
A native of the Mediterranean region, it is found in the northern Mediterranean littoral and western Europe.[4]
Cultivation
It is grown from tuberous bulbs 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.[5] It is a common ornamental garden plant, flowering in early spring. It is rather tender in the UK.[6]
Taxonomic history
After being split off from the genus Iris in the nineteenth century into a separate genus,[7] Hermodactylus, it has most recently been returned to the genus Iris,[8][9] following molecular studies at Kew.[10] According to the proposed molecular classification of irises of Tillie, Chase and Hall,[10] this species is now best seen as a member of the subgenus Hermodactyloides, the reticulate-bulbed bulbous irises.
