Irises are the largest genus of the Iridaceae family, with as many as 300 species, many of which are thought to be natural hybrids. Iris species are primarily native to the temperate northern hemisphere, the majority from Europe and Asia. The world of Irises is expansive, with species native to some of the most extreme climates, giving us an iris for just about any landscape or garden situation.
