The Curious Relationship Between Ants and Peonies
Peonies attract ants: delving into the reasons behind this recurring phenomenon on blooming perennials
Peonies, with their vibrant blooms and sweet fragrance, have long been a favourite among gardeners. But there's more to these beautiful plants than meets the eye – they also attract ants.
These tiny creatures are drawn to the extrafloral nectaries found on the outside of peony buds. These glands secrete a nectar-like substance that ants find irresistible due to its sugary nature[1][2][3]. This attraction is not harmful to the peonies; rather, it is a natural part of the plant's interaction with ants.
Contrary to popular belief, ants do not play a role in the peony blooming process. They are not required for the buds to open[1][4]. Instead, their presence is a result of feeding on the nectar secreted by the buds. Despite this, ants do provide a beneficial role by deterring other pests, such as aphids, which can harm the plant[2][3].
The relationship between ants and peonies is an example of mutualism in the garden. Ants benefit from the nectar produced by the peonies, while the ants help protect the plants from other harmful insects[5].
If you find ants on your peonies, there's no need to worry. A large number of ants can be found on peonies in spring as buds begin to open. Waiting until flowers open is another way to get rid of ants on peonies, as most ants will choose to feed elsewhere. Dipping peonies in cool, clean water after harvest can also help get rid of ants before bringing them indoors[6]. Using a hose to spray water is another effective way to get rid of ants on peonies[7].
Tonya Barnett, a gardener with 13 years of experience, has transformed her backyard into a cut flower garden and regularly shares her experiences on YouTube. According to Barnett, ants on peonies provide natural pest control for peonies by eating thrips and aphids[8]. The nectar produced by peonies gives buds a shiny appearance and makes them sticky to the touch, which helps attract ants[9]. Ants also produce pheromone trails that lead other ants to the food source[10].
In conclusion, ants are beneficial visitors to peonies, helping to protect the plants from other pests while enjoying the nectar. The next time you see ants on your peonies, remember that they're just there to help!

In the realm of home-and-garden pursuits, ants can be found on peonies, particularly drawn to the extrafloral nectaries that secrete a nectar-like substance. This lifestyle choice by ants is beneficial for both parties, as they help protect the peonies from harmful insects like aphids, while enjoying the nectar produced by the plant.
