As the name suggests, Iris is synonymous with color, and they are myriad. Shades range from white to pink, blue, lilac and purple. Some are yellow, scarlet, orange or nearly black. Others display bold combinations of colors. Most flower for about a month in late spring and early summer. But with careful selection you can have iris blooms from very early spring to mid-fall.
Irises can be found growing in habitats as diverse as cool, mountainous regions and warm, subtropical swamps. Some are drought-tolerant while others grow in water up to 10 inches deep. Most irises prefer a site with full sun and well-drained, moderately fertile soil. Many are cold hardy down to -15F. Therefore, you should be able to find a type that will perform well for you.
