26 Great Companion Plants for Peonies

Sharing is caring!

There are 26 companion plants for peonies in this list including different flowers, trees, shrubs, and even herbs. It should’nt be a surprise that the majority of the Peony companions are flowers since Peonies themselves are flowers.

Peonies are lovely and fragrant perennial plants that require specific care to thrive and bloom. These blooming plants have been grown for generations and come in a variety of colours and shapes, making them a great addition to any garden or landscape. It is critical to offer the correct growing conditions for peonies in order to promote healthy development and blooming.

Peonies grow best in well-drained soil that is rich in organic matter and has a pH of 6.5 to 7. They require at least six hours of direct sunlight every day but may also thrive in partial shade. Watering should be done on a regular basis to keep the soil equally wet but not saturated. Overwatering can cause root rot, which can be harmful to the plant.
