What is the name of these flowers shown in the picture?

Iris is a genus of 260–300 species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, which is also the name for the Greek goddess of the rainbow, Iris. Some authors state that the name refers to the wide variety of flower colors found among the many species.

The inflorescences are in the shape of a fan and contain one or more symmetrical six-lobed flowers. These grow on a pedicel or peduncle. The three sepals, which are usually spreading or droop downwards, are referred to as "falls". They expand from their narrow base (the "claw" or "haft"), into a broader expanded portion ("limb" or "blade") and can be adorned with veining, lines, or dots. In the centre of the blade, some of the rhizomatous irises have a "beard" (a tuft of short upright extensions growing in its midline), which are the plant's filaments.
