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.
Who or what consumes peony buds?
Peonies are targeted by thrips in the spring when the new leaves develop and the flower buds grow. These sucking insects feed on the plant’s leaves and buds, draining the liquids from individual plant cells and leaving behind plant material that is discolored, speckled, and shriveled as well as deformed buds. Thrips have flimsy wings and thin bodies. Due of their modest size, they frequently go unnoticed until feeding problems manifest. Eliminate thrips by using parasitic wasps or predatory insects, or by spraying neem oil or insecticidal soap on the infected plants.
What eats my peony so frequently?
Animals other than deer also like nibbling on your flowers. In actuality, quite a few creatures and insects favor peony. Therefore, it’s critical to comprehend these animals and how they may impact your home if you want to safeguard your flowers.
Rabbits, beavers, and squirrels are typical creatures that pose a serious threat to your peony. Insects like red ants and snails that like to eat peony buds should also be avoided.
Consider fencing your peony if either of these animals or insects pose a serious threat to them, or use our recommended preventative measures instead. In either case, using extra caution will help you protect your possessions and peonies.
Just like any other herbivore, deer will eventually eat any plant if they are sufficiently hungry. Therefore, it is your responsibility to take the necessary precautions to keep deer at bay if you reside close to deer or deer breeding zones. We are convinced that you will have no trouble dealing with these troublesome critters because we have provided you with a thorough set of instructions. After all is said and done, you will have a lovely garden with healthy peonies that are fully safe from potential deer assaults.

Who pollinates peonies with insects?
The peony family includes the flowering plant known as the peony. Peonies come in over 40 different species, with origins in Asia, Europe, and North America. Peonies prefer colder climates; they cannot blossom in warm climates; and for healthy growth and development, peonies need nutritious, wet, well-drained soil. Peonies are grown for both medicinal and decorative uses. Peonies are widely used to create a variety of floral arrangements due to their enormous, exquisitely colored blossoms.
Peony-related fun facts:
Peonies can develop as semi-woody shrubs or herbaceous plants (tree-like plant). Depending on the species, it can grow to a height between 1.6 and 9.8 feet.
Compound leaves of peonies can have 2 to 9 leaflets. On the stalk, green leaves are placed alternately.
Large flowers with lots of petals are what make peonies so famous. The diameter of a flower can be up to 10 inches. They have a bowl-like form and come in every color but blue. Burgundy, pink, white, and yellow peony types are the most widely used ones. Peonies have both types of reproductive organs and produce flowers (perfect flowers).
From late spring through early summer, peonies bloom. Large amounts of nectar produced by flower buds draw ants. They (ants) assist in the opening of flower buds and offer defense against dangerous insects. Flowers release a delicate, sweet scent that draws wasps and flies, the plants’ primary pollinators. Peonies are also capable of self-pollination.
The peony’s dried, seed-filled fruit is a follicle. To release the seed, ripe fruit splits.
Peony petals that have been partially cooked and sweetened are eaten in China as dessert. Fresh petals can be added as a garnish to lemonade or eaten in the shape of a salad.
In the language of flowers, peony denotes love, grace, honor, riches, and abundance.
One of the most widely utilized flowers for creating bridal bouquets is the peony. The designated flower for the 12th wedding anniversary is this one.
Peonies were referred to by the renowned merchant and explorer Marco Polo as “roses as big as cabbages.”
In the past, peony (both the root and the seed) were often used to alleviate asthma, headaches, and labor pain.
White peony root is a natural treatment for hypercholesterolemia and convulsions that also helps the liver and brain work better.
In China, the peony is a representation of prosperity, luck, and harmony. In Chinese art, it is extremely common. Because it is widely believed that peonies can bring good fortune and prosperous business, peony paintings are regularly used to decorate homes and offices.
When grown under ideal conditions, the perennial peony plant has a lifespan of up to 100 years. Peonies barely last five days in vases.
Are peony resistant to pests?
Although peonies are generally resistant to pests and diseases, there are a few maladies that gardeners should be aware of. Lack of air movement and cool, moist conditions are linked to diseases that frequently affect peony; while reducing these elements may be challenging, awareness of them can help with solutions. Creating the ideal conditions for growth will, like with all living things, prevent issues with disease and pests.
The most prevalent illnesses in peony are viruses and fungi. The greatest strategy for preventing issues with these diseases is prevention, therefore thorough fall cleanup and cleanliness during division are crucial.
Generally speaking, animal pests do not cause problems, but specific locations may vary. The most frequent offenders are rabbits and deer, who nibble on fragile tissue in the spring but rarely harm plants.
Nematodes can harm plants and occasionally even roots. These tiny, worm-like pests frequently find opportunities under specific circumstances. Cleanup and prevention are crucial in this situation as well for their control.
When it’s unclear whether a plant condition is caused by a disease, agricultural extension agents should be consulted. Utilizing the resources at your disposal will assist ensure that your peony remain healthy and a vital component of the garden. For more information, see the list of additional resources at the bottom of this page.
What causes my peonies to die?
The most prominent disease affecting garden peony is botrytis blight, which is most common during wet, rainy seasons. When young shoots reach a height of 5 to 8 inches, they decay at ground level. Stems frequently look to be drenched in water. Shoots with leaves quickly droop and fall over.
Do ants aid with peony emergence?
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).
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.
