Iris tuberosa
Also called Widow Iris, Snakeshead Iris
Iris tuberosa (formerly Hermodactylus tuberosus) is a species of tuberous flowering plant of the genus Iris, with the common names snake's-head, snake's-head iris, widow iris, black iris, or velvet flower-de-luce.
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. It is a common ornamental garden plant, flowering in early spring. It is rather tender in the UK.
A native of the Mediterranean region, it is found in the northern Mediterranean littoral and western Europe.
