Complement Your Iris Garden: The Best Companion Plants for Gorgeous Spring Bloom

Tall bearded irises and Siberian irises bloom in late spring and look great in any cottage garden or flower bed. A patch of iris can look worn out after the flowers die off and the bulbs use up all the plants’ energy to get ready for winter.

Planting iris plant companions that fill out and bloom later in the season can hide spent iris plants. Companion plants for irises can also be spring blooming flowers that accentuate and contrast iris blooms.

Companion planting is the practice of combining plants that benefit each other. Sometimes companion plants help each other resist diseases and pests. Some companion plants benefit the taste and scent of each other. Other plant companions simply benefit each other aesthetically.

Irises won’t change the taste or pest resistance of plants that grow with them, but they look great in almost all gardens. Iris tubers don’t take up much space in the garden and don’t try to take nutrients or space from other plants.

After the spring blooms, they can be tucked into spots with full sun to part shade. Iris doesnt seem to mind growing alongside any plant. They can even be grown near black walnuts and other juglone producing plants.

Iris bring elegance and grace to the garden with their distinctive flowers and sword-shaped foliage. While iris bloom for a relatively short period in spring, the right companion plants can extend your garden’s beauty before, during, and after the iris show.

By pairing iris with plants that bloom at different times, you can create stunning combinations and maximize seasonal interest. Read on to discover the best options for iris companion plants.
