Iris is a genus of species of flowering plants with showy flowers, It takes its name from the Greek word for a rainbow, referring to the wide variety of flower colors found among the many species.
As well as being the scientific name, iris is also very widely used as a common name for all Iris species,
though some plants called thus belong to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. It is a popular garden flower.
