Irises are a genus of three hundred species of flowering perennials named after the Greek goddess who was said to have rode rainbows, so named because of the rainbow of colors the plant is famous for. Irises, whose scientific name is Iris, is the largest genus of the Iridaceae family. Many of the three hundred species are natural hybrids. Once commonly called Flags, Irises are native to the temperate regions of the Northern Hemisphere, especially Asia and Eurasia.

Irises like full sun and will grow in nearly every soil type, although they prefer a neutral to slightly acidic, well-drained soil. Without enough sun, typically requiring at least six hours a day, the flower will not bloom. It is said that Irises can withstand drought that would kill most all other flowers. If the soil is too sandy, or clayish, organic matter such as compost should be added. In addition to being drought-tolerant, this flower is also deer-resistant, however the plant is vulnerable to borers, which can eat its roots.

Growing to a height of one to three feet, depending on the species, the flowers of this plant sit atop long, erect stems and appears fan-shaped with symmetrical six-lobed blooms. Three sepals drop downwards, while the three petals stand upright, although some smaller species have all six lobes pointing directly outward. Most Irises bloom in early summer, although some hybrids will re-bloom again later in the growing season. Though purple is its predominate color, the blooms also come in pink, orange, yellow, blue, white and a multi-color. Besides humans, these flowers also attract hummingbirds and butterflies.

What make the Iris somewhat unusual in a typical garden in my neck of the woods, is its rhizomes, which are fleshy, root-like stems of the plant from which it roots. The rhizomes should be exposed, unlike that of bulbs, because they need some sun and air to help keep them somewhat dry. If covered by dirt, or crowded out by other plants, the rhizomes will rot. If the rhizomes appear rotten and/or diseased, let them dry out in the sun for a few days, and any healthy looking piece can be replanted.

Clusters of the plant should be divided every three or four years to keep the plant vigorous. The plant should be divided in late summer or early fall. Do not trim the leaves back during the summer, as they carry on the photosynthesis process until late fall. Brown tips should be cut off, and the stalks of the deadheads should be cut down to the rhizomes to discourage rotting. Irises should not be mulched, as mulching retains moisture and too much moisture will rot the rhizomes.

If I am fortunate to have you view my photographs and you find the color saturation too much or the color schemes of the mats do not match either themselves or the photograph, please let me know via a comment. Being color-blind, what might look great to me might look like sh*t to everyone else!
