Genus Overview: Iris

Common Name: Iris

From small woodland species and tiny forms happy in a sunny trough to those that stretch to one's waist and higher irises are among the most beautiful and unique of herbaceous perennials. They come in an amazing array of colors with fans of foliage that provide textural contrast to other garden denizens long after the flowers have passed. None that we carry are especially common. All are beautiful in the full sun border with many adaptable to pond's edge. They want a home! Pot grown division unless otherwise indicated.
