Although their foliage is sometimes seen to be lovely, peonies (Paeonia species and hybrids) are mostly appreciated for their brilliant flowers, which come in a variety of colors and styles. The U.S. Department of Agriculture’s plant hardiness zones 2 through 8 are suitable for these plants to grow in, while individual examples often have significantly limited growth ranges. Due to their attraction to the peony petals, ants are frequently found on peonies. The peony is unaffected by these ants, however a few other insects may provide a problem for these plants.
What sort of insects are drawn to peonies?
Peonies are well known for luring ants, which crawl all over the flowers and feast on the sticky sugars they release. Whether they are outside or on someone’s dining room table, the ants leave once the blossom has fully opened and the sucrose has been digested. People who have had ants march across their dinner table and depart their centerpiece frequently have a negative opinion of peonies as cut flowers.
However, there is a straightforward fix for the ant issue, and every professional peony grower uses it: Before the petals open, cut the peonies when they are in bud. Shake or wipe off any ants that may be present on the buds. The peony should then be placed in water to begin blooming indoors.
The only tricky part is figuring out when the bud is mature enough to be cut open from the inside. The bud is at its softest and most colorful when it is at this stage. When clipped, the bud on a giant double peony like Sarah Bernhardt can measure around 1.5 inches in diameter; two days later, it will have grown to its full size.
Cut peonies can be stored in the refrigerator for a few weeks if they are at the marshmallow stage. The peony can be stored in the refrigerator’s back section after being gently wrapped in plastic with the clipped stem ends showing. (Warning: Adding apples, cantaloupes, or other ethylene-producing fruits will reduce the flowers’ vase life.) The flowers can be burrito-style wrapped in newspaper and put in an opaque plastic container in a fridge for the commercial grower. They will hold at 35 for a month or longer. Cut an inch from the stem when you are ready to use it, and then immerse it in warm, deep water. The length of time it takes for the bloom to fully open can range from eight to 48 hours, depending on how tightly closed the bud was when it was cut.
Your peony won’t have ants if you handle them this way. Additionally, they’ll be the most exquisite, lavish, and aromatic cut flowers imaginable.
Pink “Sarah Bernhardt” peonies are complemented in the image above by fuschia Dianthus “Purple Bouquet” and deep purple Campanula glomerata. On Friday morning, the peonies were placed in water after being cut in bud and kept in the cooler for a week. Sunday morning was when this picture was taken.
Do insects enjoy peonies?
The peony is typically the first flower that springs to mind when you think of springtime flowers. You might fantasize about having them all over your garden because of their fluffy pink blossoms, invigorating smell, stunning pastel hue, and ease of maintenance. However, there is a drawback to these lovely petals. Peonies, it turns out, will attract all ants to your yard. Possibly even into your house.
These blooms do in fact draw these small bugs, according to Integrated Pest Management at the University of Missouri. Ants can’t get enough of the sticky sap that peony buds produce just before they bloom. Until the flower fully blossoms, they will climb all over the buds, soaking up the sap. No harm is done to the bloom by the ants, but you may have to deal with them if they start marching across your kitchen counter.

My favorite flower is a peony. The green foliage is quite lovely, and they are so fluffy and lovely! This peony season as I’ve been gathering, weeding, and arranging them, I thought it would be a good idea to write about and explain what I do to make sure my flowers are as lovely as possible when I bring them inside. I’ve learnt a few things after growing them for five years that you might find useful. If you’re interested in learning more about how to cultivate and choose peony as well as how to deal with ants, keep reading if you’re interested.
How to Grow Peonies
From zones 3 to 8, peonies can grow. As a novice home gardener in Alberta, Canada, I am able to grow them there. My knowledge is limited to herbaceous peonies, which are shrub-type peonies that prefer full sun. Mine are in full light on the south side of my house, and they thrive there. Peony plants are widely available at the majority of gardening stores, as well as at Walmart and Home Depot. In order to ensure that you plant them at the proper depth and distance apart, plant them in late spring and pay close attention to the planting instructions that will be included with your purchase.
Just a heads up: Peony plants do take a bit to grow and begin to produce enormous, beautiful blooms. Mine lasted for around four years. I think it’s worthwhile to wait until they are fully grown because once they begin to bloom, you can enjoy these gorgeous perennial plants for many years to come! Alexander Fleming (full and vivid pink) and Sarah Bernhardt are the varieties I possess and adore (full and blush pink). Early in the spring, I like to surround my larger, more mature plants with a ring of stakes. In this way, when they become heavy with lovely blossoms, they won’t droop or topple over.
How to Store Peonies to Bloom Later
In zone 3, peonies only bloom for a few weeks in late June, but there are several simple ways to extend their blooming period! One method is to select them at the ideal moment and place them in the refrigerator. Wait until the peony bud is fully colored and marshmallow-soft to the touch. The flower bud will no longer be green during this stage, known as the “marshmallow stage,” and all that will be seen are the colored petals that are almost ready to open. Once your buds resemble those seen above, trim the stems with garden shears or a sharp knife, removing all of the leaves before gently wrapping the trimmed stems in plastic wrap. After a few weeks of horizontal storage in your refrigerator, remove them, put them in a vase with water, and watch as the petals open up.
How to Deal with Ants on Peonies
Ants adore peonies and may be a real annoyance. When you go to check on your lovely blossoms and discover an ant swarm, it is upsetting. It could be a good idea to keep in mind how crucial these tiny insects are to the maturation of peonies. They consume the nectar from the peony buds, which causes the blooms to open so brilliantly, as a food source. Even so, you still don’t want them in your home, and there are techniques to reduce their numbers so you can peacefully enjoy your indoor flowers.
Picking peonies when they are still in the marshmallow bud stage may help keep ants away from the ones you wish to cut and utilize inside. In this manner, the ants are prevented from colonizing the petals. Then you may place them in a vase with water to allow them to bloom. But be careful not to pick your buds too soon! The nectar (from the extrafloral nectaries, if you want to be nerdy about the whole thing) is what the ants need to consume in order for the peony to open. If you bring them inside before the ants have had a chance to do their thing, they won’t open correctly.
Another approach entails getting rid of ants after the petals have opened and they have established themselves inside the peony head. When your peonies have reached the stage of full opening, use this. Just hang them upside down and vigorously shake them. Before bringing the petals inside, remove any remaining insects. To be sure, you can also soak the flowers outside in a bucket of water while they are upside down to get rid of bugs. My preferred method is to soak mine for about two hours, shake them well, and then bring them indoors. I can assure you that this method effectively eliminates the ants while causing them no harm at all.
What is consuming my petticoats?
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.

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.
Why are my peonies covered in ants?
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).
Do flies like peonies?
Fly attraction to a fluid given off by your peony buds is the cause of their appearance. For the same reason, you can also detect ants on your peony buds. It’s a common misconception that ants and flies are required to open the buds by nibbling on them, but this is untrue. The buds naturally open. However, flies and ants continue to visit your peony just for the chance to feast on the sweet, honey-like plant sap. Ants, like flies, don’t harm peony buds.
