Ants enjoy peonies for the same reason that we do—they are delightful. You’ll observe sweet nectar droplets surrounding the bloom’s green exterior as the flower buds develop (called the sepal). Ants adore sugar, as we all are aware. It makes sense that they would be drawn to this sticky honey.
This frequent occurrence gave rise to the misconception that ants are necessary for peonies to blossom.
According to the hypothesis, in order for the buds to open, the sticky substance must be removed by the ants. However, this myth is wholly wrong. Peonies will bloom with or without a few ants’ assistance (it makes for a wholesome story though).

The “king of all flowers,” peonies, are currently giving Missouri a breathtaking display of blossom color. However, ants also appear as the peony plants begin to bloom. Ants on buds and blossoms can be a pain, but they don’t hurt anything (Figure 1). Ants leave peony flowers after bloom is through and go on to seek out another food source.
It is untrue that ants are necessary for peonies to bloom. Peonies and ants have a mutualistic relationship in which both of their activities are beneficial to the other species of organisms. Ants eat the nectar from peony blooms, and in return, the ants defend the flowers from other insects that consume flowers.
It is possible to find extrafloral nectaries outside of peony flower buds. These plant organs exude nectar, which serves as an ant food supply since it contains sugars (sucrose, glucose, and fructose), amino acids, lipids, and other organic substances. A scout ant leaves a pheromone or odor trail on her journey back to her colony after finding nectar on a peony. The scout informs other ants at the nest of the food supply. The recruited ants then return to the nectar-filled peony blossoms by following the olfactory trail.
The ants guard their food supply from other insects that come to dine on the flower buds while they are consuming the nectar. The odor trail is reinforced when each ant consumes peony nectar, continuing until all of the food has been consumed. This kind of insect behavior is an effective way for them to make use of a transient food source.
An insecticide need not be used because the presence of ants on the floral tissues of peonies is only transient. Holding the peonies upside down by the stem immediately below the flower, shake the ants off outside or gently rinse them off before arranging them when cutting peonies at full bloom for indoor use. Cut plant stems while flower buds are in the “marshmallow stage” to assure ant eradication, and wash any ants off with water before bringing them inside (Figure 2). Flower buds are currently closed but displaying some color. Squeezing flower buds between the forefinger and thumb will also feel velvety. When marshmallow-stage buds are taken indoors, full bloom usually happens within 8 to 48 hours of putting the stems in water. Cut stems containing flower buds can also be refrigerated for subsequent bloom production.
Thrips, a common insect that feeds on peony blooms, are not like ants. These tiny (1 to 2 mm long), thin insects use their mouthparts to penetrate flower petals and draw liquids from the plant tissues, resulting in flowers that are discolored or have blemishes. Heavy infestations that obliterate peony flowers are quite uncommon. See the most recent IPM article, “Plant Peonies in September,” for more details on cultivating peonies.
Are ants bad for peonies?
Do ants actually aid in the blooming of peonies? Ants “tickle the buds to assist the flowers open,” according to myth about gardens. There is a beneficial relationship between peonies and ants, but it’s not what you may imagine. The tale of peony and ants is presented here, along with advice on how to bring peonies indoors without attracting ants.
We celebrate the breathtakingly gorgeous peony blossoms in the late spring. But those of us who have peonies in our gardens might also note the ants’ appearance, particularly in or near the base of the flower or on unopened buds.
Are Ants Harmful to Peonies?
Let’s answer this initial query first. No. Without a doubt. Avoid sweeping those ants under the rug or, even worse, using insecticide!
Ants are not only NOT dangerous, but they are also a prime illustration of biological mutualism. The ants guard the peony from aphids, thrips, and other harmful insect pests while the peonies supply nectar (food) for the ants.
Do Peonies Need Ants to Bloom?
The persistent misconception is that ants are necessary for peonies’ buds to open. You may have heard that for peonies to blossom, ants must “tickle the buds” or “lick the sugar.”
As with most mythology, this claim may have once had a glimmer of reality, but we haven’t yet seen proof of it. (We also appreciate that this legend keeps ants and peonies alive while letting nature run its course.)
Why Ants Are Attracted to Peonies
Simply put, the sugary drops (nectar) that are present at the base of the green sepals that encircle a peony bud are what attract ants. Due to the presence of amino acids, lipids, and other organic substances in addition to sugars, this is an excellent food source for ants.
The peonies ARE NOT being eaten by the ants. A scout ant leaves a pheromone or odor trail on her journey back to her colony after finding nectar on a peony. The scout informs other ants at the nest of the food supply. The recruited ants then return to the nectar-filled peony blossoms by following the olfactory trail.
In return, the ants offer some defense for the plant! The ants attack other bud-eating pests while they are consuming the nectar by stinging, biting, or acid-spraying them before tossing them off the plant in order to preserve their food source.
The ants are also transient. The ants will leave the peony flower once it has bloomed and move on to look for other food sources.
Again, even if there are ants present (for example, if you live on a rooftop), the peony blossoms would still open.
How to Get Rid of Ants on Peonies Before Bringing Indoors
While we appreciate our garden’s pink, crimson, and traditional white peonies, we also like bringing their beauty and smell inside. But how can we prevent bringing ants inside as well?
There are several approaches:
- When the dew is still thick and most of the ants are not yet present, cut the peony early in the morning. Turn the peonies upside down while holding them by the stem just below the flower (to prevent their heads from breaking off). Give the stems directly above the flowers a few solid taps. This aids in removing insects and spiders. Apply the correct amount of force for the stem.
- Watch the ants emerge after dipping each peony bloom in a large dish of chilly water outside. They won’t be able to crawl out if the dish is overfilled. To avoid picking up more ants, gently shake/tap the water off the flower and place the stem in a prepared vase. The water in the dish can then be returned to nature, along with the ants.
Cutting the peony flowers before the buds fully open is yet another technique used by expert growers. To get the peony’s buds to open indoors, you must clip it while they are at the “marshmallow stage” (see photo above).
Why are peonies a draw for ants?
Peonies that are just beginning to bloom release nectar that ants use as food. When ants find this food source in your flowerbed, they will climb up the stem, eat everything there is to eat, and then eventually move on to another plant.
Denise Fasanello, a florist, adds that there is absolutely no harm done to these lovely perennials if there is an ant infestation. She describes the insects as “not like flies or specific kids of aphids that you need to spray to eradicate.” If you observe them in your garden, they won’t harm your plants in any way.
Fasanello also refers to the widespread misconception that ants are necessary for peonies to bloom. Peonies have a somewhat sap-like coating, and it has long been believed that the ants are necessary for the peonies in the garden to open by eating the sap. But regardless of whether an ant is eating or sucking the sap off, they will still open.

Why don’t my peonies blossom despite budging?
Your peony could not experience enough cold during the winter if you reside in a warmer location. For peonies to form buds and bloom, a specific quantity of cold weather is required. It’s possible that your peony just receives the slightest amount of cold weather to for the buds to form but not enough to cause the last few flowers to open. Make careful to create an environment that might add a little bit extra cold if you think this is your issue. Do not mulch or cover the area where your peony is growing throughout the winter.
In the winter, make an effort to remove any obstructions that might be keeping the wind from your peony bed. Even though it might seem paradoxical, if you reside on the cusp of how much cold a peony requires to completely flower, this might be the extra bit of cold your peony needs.
Your peony needs your patience. Despite the fact that she is finicky, she is well worth the catering so that she can appreciate her flowers.
How can I grow my peony garden?
After being moved or planted from nursery stock, a peony may take a year or two to adapt to its new location and bloom. Plant peonies in full light and at the proper depth for most types. Consider shifting the plants if the location is too shady for your peonies in order to promote blossom output. The best location, however, offers some relief from the heat of the day because a little afternoon shade can assist extend flowers once they have opened.
The garden’s soil fertility is another thing to take into account. In order to boost the likelihood of blossom production, try feeding your peony with a liquid fertilizer in the spring.
For peonies to bloom, cold weather is also necessary. You might observe that your peonies generate flower buds that never open if you reside in a warm area. Don’t mulch or cover peonies over the winter, advises Gardening Know How, to cool them off if they become too warm during the cold weather.
Your peony will repay you with abundant flowers and may live for many generations if given good care.
Peonies should be deadheaded, right?
One gardening activity that has several advantages is deadheading peonies. Look at these!
- Increasing Plant Quality These hardy perennials may concentrate their energy on growing the plant itself as they don’t have seed heads or discarded blooms to worry about. This might comprise:
- expanding the tuber
- storing up energy for the coming year
- Putting down stronger roots
- Cleaning the Garden
- Once the peony plant has finished blooming, the unattractive part can be removed by simply snipping away the spent flower heads. Keep the greenery to help you conserve energy for the following season.
- Simple, quick, and satisfying
- Peony deadheading is a quick, simple, and satisfying yard task. When you next just have five or ten minutes to spend in the garden, this project is ideal.
- Future Blooms will be larger
- Do it even though it’s unlikely you’ll see more peony flowers this year. Peonies will produce more and better flowers in the future if deadheading is done.
- Increasing the Plants’ Compactness
- Our peonies are allowed to grow until they die back in the fall, so removing the deadheads helps the plants become a little more compact. This gives us some room in the garden to grow other flowers in front of or behind them, such as hyacinths, sunflowers, or zinnias.
Do you know of any more advantages to deadheading peonies? These are my favorites and make spending a bit more time with these plants worthwhile.
Do peony in general draw ants?
Peonies may become lanky and need staking to support their blooms if planted in partial shade.
The peony is a favorite flower among gardeners in the South. These sought-after beauties may even be cultivated in backyards, and the vivid, billowy flowers steal the show in cut bouquets. In spring, peonies that are in bloom are welcomed into garden beds, but the swarms of ants that swarm to the flowers are not. Wait a moment before using the pesticide; it’s not a bad idea. Peonies are not harmed by ants; in fact, the creatures aid in their defense. According to the University of Missouri, it is a fallacy that ants help peonies blossom, but the two actually have a positive association.
A sweet, sugary nectar that is secreted by peony blossoms draws ants. An army of ants immediately locates the food source after one ant emits a pheromone to the colony when she discovers a nectar-rich bloom. How is this beneficial to peonies? The ants chase off other insects trying to eat on the peonies in order to defend their prized food source. There is no need to apply insecticide to get rid of the ants because once the nectar is gone, they will depart the flower in search of other sources of sustenance.
Snip just-opening peonies for cut flower bouquets (they will have a longer lifespan in a vase). Make sure no ants are bringing the blossoms inside with them. To get rid of any ants, submerge the chopped peony heads in a bucket of water. Plant peonies inside in the fall for spring blooms. Due to their need for colder winters and the fact that they frequently take two to three years to produce their distinctive show-stopping blooms, these flowers can be challenging to grow in Southern backyards. But good news for you: It is simple to find peonies at nearby grocery stores and flower shops for usage in bouquets and cut arrangements.
