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.
Do ants actually aid with peony blooming?
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).
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.

Do ants help you open 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 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.
Do ants harm peony bud growth?
Small holes with a ring of finely excavated earth, each bordered by a brick-built border, started to form at the base of my raised beds at the end of March in the balding section of lawn. These are entrances to an underground network of tunnels and chambers containing a queen and her colony of 4,000–7,000 workers, which were excavated by black garden ants (Lasius niger).
The workers seek widely for food while the queen stays underneath, following smell trails left by scouts. They have found my herbaceous peonies to be seductive for the past two weeks, ascending the two-foot stems to gorge themselves on the sweet nectar released by the tightly bound flower buds. Viscous globules along the border of the sepals and ooze from the nectaries at the base of the bud.
This is still a mutualistic relationship, despite the fact that the theory that the buds would be trapped closed and unable to flower without the help of ants has been discredited. The ants protect the peony plant against hazardous, sap-sucking, petal-chewing insects without harming the flowering peonies.
I observe three ants consuming the same fat bud, each of which has a distinct foraging strategy. One circles the globe in a spiral motion from bottom to top, another moves along it in a straight line, and the third moves in a radial, bicycle-spoke pattern back and forth.
Today, though, is quiet enough for one of the glossy black-brown insects to pause and clean its antennae, using its front legs to comb them from root to tip. At times, there are so many of these insects waiting to reach a bud that a line forms beneath the calyx. Ants utilize the delicate hairs on their antennae to communicate, smell food, and follow pheromone trails, therefore grooming is essential.
The ant and peony friendship is only fleeting.
The ants will leave the plants as soon as the blooms open in search of fresh food sources. Even though the first petals have only just started to open, some of the workers have already changed from being hunters to farmers. They have moved into my broad bean patch and are taking care of herds of black fly (Aphis fabae), which they are milking for their honeydew.
How can you ensure that peonies bloom all summer long?
Gardeners simply can’t get enough of peonies’ enormous, sultry flowers, which are a mainstay of perennial borders. It’s understandable why we would wish to prolong the blooming season of these exquisite charmers if they also had a nice, seductive aroma.
Peonies are incredibly resilient to pests, have a long lifespan, and need little maintenance to produce vibrant flowers. The only issue peony farmers have is that they wish they had more time to enjoy those magnificent flowers. Let’s look at several ways to prolong peony blooming in your garden.
Peonies can bloom for over a century, almost by magic. Every plant will produce several flowers, and each bloom lasts for about 7 to 10 days. Planting kinds of peonies that bloom at various times during the about 6-week period of proficient flowering is the easy trick to extending peony blooming in your garden. Since different varieties bloom at various periods of the year, we have neatly categorized them as early, early-mid, mid, and late season. So now that you have mastered prolonging the peony blooming season, let’s take a closer look at each type.
Why did the buds on my peonies turn black?
The buds wither and turn brown or black when they are still young. It was once believed by experts that the fungus botrytis blight, also known as bud blast of peony, was to blame for this condition. It is now understood that poor cultural care frequently contributes to peony difficulties.
Hyacinth
Hyacinth blooms, which bloom in dense clusters, have an extremely fragrant scent that is earthy, sweet, and powerful. They are a favorite of both florists and gardeners and come in a variety of colors, including purple, pink, lavender, and white. As the hyacinth blossoms, its perfume intensifies and becomes more seductive.
Freesia
Many people relate the delicious aroma of freesias to that of fresh strawberries. They are among the most well-liked flowers in the entire globe because to their delicate, multicolored petals and lovely, airy aroma. Freesia fragrance is frequently used in soaps, lotions, shampoos, and perfumes. Freesia’s sophisticated scent complements other, flashier flowers like peonies and roses. Anyone would be surprised with a sweet and fragrant bouquet if it contained freesias.
Rose
When seeking for a flower with a beautiful scent, roses are frequently the first choice because of their deep, opulent fragrance. But there are numerous fragrances that roses can have. Red and pink roses in particular have a richer, more perfume-like aroma that many people are accustomed to. However, roses with lighter hues can smell more delicious and lemony. Since ancient times, people have loved and cherished roses, which were highly prized for their exquisite and enticing blooms. It was believed that the seductive scent of roses helped people unwind and focus.
Peony
Peonies have a fresh, sweet perfume that can fill a space in addition to being a lush, stunning flower with calming, lovely colors. Peonies come in a variety of scents, from sweet and rose to lemony, some of which are stronger than others depending on the kind. The most fragrant peonies are usually the double, white, and pink varieties.
Sweet Pea
Sweet Peas are another flower with a perfume that is frequently used in lotions and other bath products. The exquisite Sweet Pea exudes grace and elegance with its paper-thin petals that come in shades of white, pink, and purple. Sweet peas blend well with other fragrant blossoms because their perfume is not overbearing.
Lily
One of the strongest-smelling flowers in existence is the lily. These enormous, striking flowers are ideal for any occasion and available in a variety of hues. The potency of a lily’s perfume varies depending on the kind. Lilies with the strongest scents are Starfighter lilies, while Sonata lilies have a more mild, delicate perfume.
Lavender
The herb known as lavender has lovely clusters of purple flowers and a calming, calming, and pleasant aroma. Lavender aroma has been utilized for generations in oils, scented waters, soaps, and perfumes.
As in the case of our Peony Paradise bouquet, an arrangement of several fragrant flowers is not only a stunning sight to behold but also a satisfying and overwhelming delight to smell. A present like this will make the receiver feel extra special if it includes roses, lilies, and peonies.
