Just like humans need companions to thrive, plants also need companions to thrive. Planting all of the same types of bush, tree or flower is no fun! Planting a limited selection of plants can also lead to problems if a disease or pest comes and wipes out that entire type of plant. When planning your garden with bearded iris it is important to plant bearded iris of different colors and heights together. It is also effective for balance to plant flowers, trees, shrubs and bulbs that complement the bearded iris.

Bearded Iris may already be a part of your garden and you want companion plants to make the space more diverse. Perhaps you don’t have bearded iris in your garden but want some late spring color from this colorful group of flowering perennials. If you enjoy bearded iris and want to make the most out of these late spring blooming perennials read more.

Plants that Bloom with Bearded Iris

Bearded Iris are late spring to early summer blooming perennials. These fall-planted bulbs put on their best display in May and June depending on where you are located. To get the most of your planting area you will want to plant perennials and bulbs that bloom around the same time to compliment the bearded iris in your garden.

Allium and Bearded Iris

Bearded Iris + Allium: Allium are popular fall-planted perennial bulbs that grow and bloom in spring. The combination of bearded iris and allium are the grand finale of the spring bulb flower season as they are the last of the fall-planted bulbs to bloom. Allium are generally available in purple, pink or white blooms. Bearded Iris are available in nearly every color of the rainbow, which makes the color combinations of allium with bearded iris expansive. Try combining Purple Sensation Allium with a selection of iris such as Anvil of Darkness Bearded Iris, Imbroglio Bearded Iris and Immortality Bearded Iris for a stunning display. The combination of purple allium and iris with the white Immortality Bearded Iris is a classic combination of rich contrasting colors.

Peony and Bearded Iris

Bearded Iris + Peonies: Peonies and Bearded Iris are colorful, showy and put on a spectacular display in late spring. Peonies and Bearded Iris reach similar heights at maturity, generally in the 3-4’ range. However, the overall shape of the iris and peonies is much different. Peonies have a shrub-like appearance with attractive foliage, while iris have an upright appearance with thick grassy leaves. Planting irises and peonies together creates a double impact with blooms appearing at the same time. Depending on the variety of iris and peony you may want to plant the iris behind the peony so that the peony masks the foliage of the iris. If the variety of Iris you are planting grows shorter than the type of peony you are planting, you will need to plant the iris in front of the peony. My favorite combination of peonies and bearded iris is one that represents the pastel colors often represented in the spring season. I like to plant light pink peonies like Eden’s Perfume Peony or Plena Rosa Peony with pastel blue iris such as Victoria Falls Bearded Iris. The combination of light pink peonies with light blue iris screams spring to me!

Poppy and Bearded Iris

Bearded Iris + Oriental Poppies: This combination of late spring blooming perennials offers different textures as well as diversity in the mature height between the two plants. Oriental Poppies are a bit lower to the ground compared to bearded iris so they should be planted in front. Poppy varieties like Harlem Oriental Poppy pair well with the light pink color of Lotus Land Bearded Iris. Perry’s White Oriental Poppy with its large white blooms complements any color of bearded iris and is a must-have perennial for your late spring garden. Both oriental poppies and bearded iris prefer soil that drains well and performs poorly in waterlogged soils. Similar growing conditions of well-drained soil and full sun make poppies and iris a match made in heaven!

Catmint and Bearded IrisBearded Iris + Catmint: Catmint is a sprawling perennial with pale blue flowers. It begins to bloom at the same time as bearded iris. Due to the sprawling habit of catmint, it is a nice companion plant as it helps to cover the foliage once the blooms are gone on the bearded iris. Compact varieties of catmint like Kitten Around Catmint only grow 12-14” which make them the perfect partner for tall blue iris such as Blueberry Bliss Bearded Iris or Stairway to Heaven Bearded Iris.

Cranesbill and Bearded IrisBearded Iris + Cranesbill: Cranesbill also known as hardy geranium are another perennial with a sprawling habit that pair well with bearded iris. Some varieties of cranesbill have a bloom season that begins in late spring and extend throughout summer. Most cranesbill put on their heaviest display of blooms in late spring to early summer when the bearded iris are also starting the bloom. The low growing habit of cranesbill planted in front of the bearded iris makes for a delightful combination. The deep purple blooms of Raven Cranesbill look stunning planted with the peach blooms of Beverly Sills Bearded Iris.

Columbine and Bearded IrisBearded Iris + Columbine: One of the more unique spring-blooming flowers are columbine. With a much daintier appearance than bearded iris, the texture combines well with the iris. Columbine flowers begin blooming in mid to late spring and serve as a lovely addition of late spring blooms in the garden. Columbine can be planted in front of or surrounding the bearded iris, as their airy appearance, shorter height, and unique blooms should be visible. Mixed Columbine are a classic spring favorite to combine with warm-colored bearded iris like War Chief Bearded Iris, Bold Look Bearded Iris, and Avalon Sunset Bearded Iris.

Salvia and Bearded Iris

Bearded Iris + Salvia: Salvia also known as Meadow Sage are some of my favorite perennials! I enjoy the vivid purple, pink and blue colors salvia blooms provide. In addition to the vivid colors, the long bloom time of salvia is appealing. Salvia begins their bloom season in early summer which coincides with the end of the bearded iris bloom time. Since the salvia bloom so close to the bearded iris these flowers help to transition the bloom seasons from spring to summer. May Night Salvia is a popular variety, which is best planted in spring and matches well with yellow, purple or white bearded iris.

Think of your Future Garden

For a well-balanced garden, it is important to plant perennials, shrubs, and trees that will have similar bloom times to your bearded iris. It is also important to think about your garden in the weeks and months that follow the bearded iris bloom season. Planting perennials that bloom in mid to late summer in the area your bearded iris are will help to ensure color throughout the summer. In addition to adding color this will help to balance the texture that bearded iris leaves have, as they can be a bit difficult to blend into the garden. Planting perennials like daylilies that have foliage which will blend with the bearded iris and bloom later in the season will extend the color and interest in that area of the garden. In addition to extending the color and interest daylilies tend to be drought tolerant once established, which is a great pairing for bearded iris since they like soil that is on the dry well-drained side. Other perennials and bulbs that bloom later in the season that can be planted in the same garden area as your bearded iris are: Black-Eyed Susan, Coneflower, Oriental Lilies, Sedum, and Tall Garden Phlox.

Planning and planting your perennial garden is fun, exciting and test of trial and error. Knowing where to start with companion plants is the first step to planning. I hope these ideas have inspired you to add to your bearded iris planting areas, or start a new area in your garden with colorful bearded iris and early, mid and late-flowering perennials!
