Flower of the Week: Iris

Iris plants belong to an enormous plant family, Iridaceae, which also includes perennial garden favorites like crocuses, freesias, and gladioli.

The image of the fleur-de-lis is thought to have been based on the iris, and orris root, a fragrance used in perfumes and potpourri, as well as Absolute Vodka and Bombay Gin, is derived from the powdered rhizomes of several European species of iris.

The Greeks named the flower after their god of the rainbow, Iris. These early Greeks often planted irises on graves, since it was the duty of the god, Iris, to lead the souls of dead women to paradise. The many colors and forms of iris make it possible to create a corner of paradise in the garden. Late summer is the best time for starting a new iris bed or for reworking an old one.

The most popular of irises is the German or bearded iris that grows from a thickened underground stem called a rhizome. This structure usually grows parallel to the soil surface and just slightly under it. Although some iris, such as the Japanese iris, like moist locations, the popular garden types need excellent drainage. They flower best in a sunny location.

People not familiar with iris - or who only have seen a few varieties - may be astonished by the range of color and form. From whites and yellows to deepest violet and maroon, and with bicolors and variegated styles as well, the elegant flowers are a visual feast.  Thousands of irises can be found on just about every continent in the world.
