The name, Iris, comes from the Greek word for the goddess of the rainbow, possibly referring to the diverse range of colors that irises are available. Named after a goddess, the iris flower has also been revered all over the world. In Japan, for example, irises were admired as a symbol of purity, cleansing and protection from any evil energies, which is why irises can often be found in kimono fabrics, woodblocks and more.
