This is an easy to grow tuberous plant from some of the more milder parts of Europe and the Mediterranean. Once categorised as an iris, it now has it's own genus but often classified as an Iris and essentially, looks like a dark flowered iris. Flowers are on top of 40 to 50 cm stems and are green and black with the foliage being thin and grassy.
Easy to grow in full sun and any well drained soil.
