Iris tuberosa is a species of non-rhizomatous plant of the genus Iris, with the common names snake's-head,[2] widow iris, black iris, or velvet flower-de-luce.

Distribution[edit]

A native of the Mediterranean region, it is found in the northern Mediterranean littoral and western Europe.[3]

Cultivation[edit]

It is grown from tuberous bulbs planted in the autumn. It grows best in full sun to partial shade, and requires well-drained soil. In can naturalise in grassy areas but grows well in rock gardens or containers.[4] It is a common ornamental garden plant, flowering in early spring.

Taxonomic history[edit]

After being split off from the Iris genus in the nineteenth century into a separate genus,[5] Hermodactylus, it has most recently been returned to the genus Iris,[6][7] following molecular studies at Kew.[8] According to the proposed molecular classification of irises of Tillie, Chase and Hall,[8] this species is now best seen as a member of the subgenus Hermodactyloides, the reticulate-bulbed bulbous irises.
