Best Companion Plants for Bearded Iris

customer question customer question

"Last August I planted some Bearded Iris in two very different spots on my property - one bed is very formal, and the other is more of a wild & natural look. I chose to plant shades of blue in the formal bed and multiple colors in the natural area and was delighted by how beautiful they looked when they flowered this spring. Now I would like to make them the focal point of these gardens, both of which are quite new. Can you recommend some perennial plants that may complement my Bearded Iris plantings?" - Stacey B., Vineland, New Jersey

All About Bearded Iris

Bearded Iris (Iris germanica) is a member of the genus, Iris, named after the Greek goddess of the rainbow. As the myth goes, when the gods wanted to communicate with humans, they sent Iris, who arrived with golden wings. As she stepped to earth, colorful flowers sprung forth. It’s almost hard to imagine a better name for this kaliedoscopic species! With thousands of colorful combinations, Bearded Iris is one of the most popular garden perennials. With endless choices of color, texture, pattern, and form, this flower opens the doors for garden creativity.

To communicate clearly about Bearded Iris, it’s helpful to know a little nomenclature.

  • There are six petals. The three upward reaching petals are called “standards,” and the three petals that drape downwards, are known as the “falls”.
  • The most distinguishing feature of Bearded Iris is their fuzzy "beard" located at the upper base of the falls.
  • Bearded Iris grow from rhizomes - bulb-like, tuberous roots, with a fan of elegant sword-shaped leaves.

Bearded Iris comes in several size ranges with differing bloom times.

  • Miniature Dwarf Bearded Iris are tiny, ranging in size from 5-15 inches tall. These great for a rock garden or border.
  • Standard Dwarf Bearded Iris range from 8-16 inches. These are great with later blooming tulips.
  • Intermediate and Border Bearded Iris grow from 16-27 inches.
  • Tall Bearded Iris grow from 28-48 inches tall. These blooming from late spring to early summer with large flowers.

Actual bloom times will vary, depending on the weather. Each flowering stem will hold several buds that will come into bloom sequentially, usually lasting 3-5 days. Once it is finished, simply snap it off with your fingers to keep a clean look and to keep more flowers coming. After all the buds have bloomed, cut the stem back near ground level.

Reblooming Bearded Iris

Many new hybrid Bearded Iris are offered as rebloomers. This means the Iris will bloom at its usual bloom time in the spring, and then come into bloom again at the end of the season, towards fall. The plant will grow new fans of leaves, putting up fresh flowering stems. It’s important to note that reblooming is not guaranteed and can be affected by location, sunlight and even the weather.

Our Top Picks For Tall Bearded Iris Companions

Use white flowering Oriental Poppies for a calming effect, red for a pop of color, or peach colored flowers for a soft look. They will die back in summer, so plant other perennials in front of them to hide the dying foliage. Plant Oriental Poppy Seeds or Perennial Oriental Poppies (plants available seasonally).

Allium

Alliums give a sculptural element to the garden, and are available in several heights, from short to very tall. They are easy to grow and long lasting pollinator favorites.

In an informal setting, tall Allium planted throughout a perennial garden make great garden features with a whimsical feel. Fall-planted Allium Bulbs are available in pink, blue, white, yellow, or classic purple (bulbs available seasonally).

Delphinium

The lovely tall wands of Larkspur (Delphinium) are excellent choices to grow with Bearded Iris. Shades of purples, blues, pinks, and white offer lovely accompaniment for a late spring display. Plant Rocket Larkspur Seeds or Perennial Delphinium (plants available seasonally).

Baptisia

Baptisia, also known as Indigo,  is a great choice in shades of yellows and blues. Try yellow Baptisia with white, gold or blue Iris. Blue flowering Baptisia is lovely with Bearded Iris in blues,purples, or other contrasting colors. Plant Indigo Seeds or Baptisia Plants (available seasonally).

Peonies are one of the most well-known spring blooming perennials.

More Bearded Iris!

With their wide array of colors, sizes and bloom times, mixing more Bearded Iris into your existing bed can increase the season of blooms with a kaleidoscope of colors, patterns, and textures.

If you have a reblooming variety, remember to add in some late season bloomers like Agastache, Aster, and Salvia.
