35 Different Types of Iris Cultivars For Your Flowerbeds
Thinking of growing some iris flowers in your flowerbeds this season, but aren't sure where to start? There are many different types of iris you can grow, depending on your hardiness zone. In this article, certified master gardener Liz Jaros shares her favorite iris cultivars you can grow in your garden this season.
Contents
Prized for their upright, fanning foliage and ruffly, trademark blooms, irises are easy to identify in the landscape once you know what you’re looking for. Although they vary in size, most flowers have three upright petals called standards, and three down-drooping petals called falls.
Some have beards while others have signals to attract pollinators, and most resemble some sort of face with an open mouth or an extended tongue.
Blooming early in the growing season, after spring flowering bulbs have wrapped up their show, but before the summer stars have taken the stage, irises are often grown precisely for their ability to fill the flower gap during this time period.
They are also selected for their lovely scents, long-lasting leaf structure, and timeless elegance. Although they bear many physical similarities, irises also have many distinct differences.
If you live in a part of the world that has extreme winter temperatures, you’ll probably gravitate toward a German or Siberian iris. If you live near water, you may want to explore a Japanese or Louisiana variety. And so on.
To help you explore your many iris options, we’ve gathered photos, descriptions, and growing profiles of our favorite cultivars. Pay careful attention to hardiness zones, flower heights, and moisture requirements before making your final choices, and you’ll be off to a good start.

As a bulb iris, ‘Katharine Hodgkin’ will spread easily by bulblet and can take over a large area fairly quickly once established. Members of the dwarf class can handle a bit more shade than other irises, so they’re often encountered near the forest’s edge or under a thin tree canopy.

This Species group iris is native to the swamps and wet meadows of North America and gets its name from the zig-zag pattern of its flower stems.
Each bloom features arching violet standards and richer-hued falls with yellow signals. Bright green sepals cradle the blooms, adding another layer of color.
Foliage is sometimes taller than flower stems, giving ‘Zigzag’ a unique personality. While this cultivar originates from wild, wet regions, it can grow quite well in a more controlled landscape setting if properly cared for.
‘Milky Iris’
botanical name Iris lactea ‘Milky Iris’ | |
plant type rhizome, perennial | |
sun requirements Full sun | |
height 6 inches to 2 feet | |

Final Thoughts
Once you’ve selected a variety or two to try in your own landscape, pay careful attention to planting and maintenance instructions for your specific cultivar. While irises are generally considered easy to grow, gardener error is usually responsible for both major and minor disappointments with the genus.
Always plant both rhizomes and bulbs at the proper depth, and plan to divide your plant every couple of years after it establishes. These are the top two reasons for diminished flower production on an iris cultivar.
Provide even watering and well-drained soil to irises that need dry roots, but make sure water-loving irises are adequately drenched. Meeting these specific needs will go a long way toward helping you achieve the iris garden of your dreams.
