Iris tuberosa

Iris tuberosa

Iris tuberosa (formerly Hermodactylus tuberosus) is a species of tuberous flowering plant of the genus Iris , with the common names snake's-head, ^[4] snake's-head iris, ^[5] widow iris, black iris, or velvet flower-de-luce.

Distribution

A native of the Mediterranean region, it is found in the northern Mediterranean littoral and western Europe. ^[6]

It can be found in Albania, France, Greece, and Italy. ^[7]

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

Illustration from 1801

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.
