With striking uniqueness and beauty, irises have rich meanings, and when given as gifts, they can convey deep sentiments. With over 200 varieties in a wide spectrum of colors, the iris, which fittingly takes its name from the Greek word for “rainbow,” can be found in virtually every part of the world, growing both naturally and in farms. While garden irises can come in any of these many varieties, the flower’s cut versions are mostly blue (the most popular type), white, and yellow. Through its complex history, the meaning of the iris has come to include faith, hope, and wisdom. Depending on factors such as color and region, irises may bear additional meanings as well. In some parts of the world, the dark blue or purple iris can denote royalty, whereas the yellow iris can be a symbol of passion. Irises may also express courage and admiration.
