Any gardener who finds one of their prized perennials covered in insects is sure to feel shocked. But do you need to worry if you find ants on peonies? Some may repeat the old myth that peonies need ants to bloom. But we'll uncover why this is urban legend, dig into the real reason why there are ants on your peonies, and share what you can do about them.

Do Peonies Need Ants to Bloom?

There are several misconceptions and myths surrounding ants and peony buds. However, they do have a hint of truth in them, which is likely why they persist.

One common belief is that ants are required for peony flowers to fully develop. There is no truth to this claim. Ants have no impact on bloom production. Another common misconception is that peonies need ants to bloom. Some even say that ants help pry open peony buds, allowing the flowers to unfurl. So is there any truth to this myth? Do peonies need ants to bloom? No, they don't.

Though ants do not play a role in peonies' ability to bloom, they are beneficial to the plants. Experts suggest that ants aid in pest prevention, which protect peonies as they begin to bloom.

Why Do Peonies Attract Ants?

For first-time growers, finding ants on peony buds may seem a bizarre or unsettling sight. However, this is a wonderful example of mutualism in the garden and no cause for concern. Ants and peonies have a relationship that benefits both parties.

Peonies produce a nectar that ants can't resist. The nectar gives buds a shiny appearance and makes them sticky to the touch. Nectaries (the structures that produce nectar in peony plants) are located just outside each bloom. These outer sepals protect the petals before opening.

The sweet nectar draws ants from the garden to peony buds to feast. Once they are there, ants provide natural pest control for peonies. These beneficial insects not only eat nectar, but also troublemakers like thrips and aphids, which can damage peony plants as they begin to bloom in spring.

Ants also produce pheromone trails that lead other ants to the food source, allowing for large numbers to find the peony bud. This is why you often see peonies teeming with ants in spring as buds begin to open. Don't worry, though, these insects do not harm the plants in any way.

How to Get Ants Off Peonies
