About the genus

Named after the Greek goddess of rainbows, Iris is both the genus and the common name for these lovely perennials. This is also the genus on which the Iridaceae, or iris family, is based. Iris are native throughout the Northern Hemisphere, in a wide range of habitats including woodlands, meadows, wetlands, and riverbanks, but the majority of species are actually found in semi-desert areas and rocky mountains. Irises may be rhizomatous perennials or bulbs, with long, blade-like or grassy leaves and flowers in virtually every color of the rainbow, which is thought to be the origin of their name.

Uses

Iris come from such a wide range of habitats, they can fit into any garden. Many can be grown in containers or perennial beds and borders, cottage and cutting gardens. Semi-aquatic types like Japanese, Siberian, or Louisiana iris can be grown along pond margins and in rain gardens. Smaller types like the bulbous Iris reticulata irises make great additions to rock gardens. Some species are also grown in rock walls and roof gardens, like Japanese roof iris.

Care

Care for irises is almost as varied as they are. Different species may be adapted to rich loams, clays, or lean, rocky soils, from sun to shade, with some species wanting even moisture all year, some wanting drier winters, and some wanting dry summers. Iris are deer and rabbit resistant but some varieties are attractive to slugs and snails.
