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.
Why won’t ants stay away from my cut flowers?
Do you have any advice on how to keep ants away from peony and dahlia flowers? Although I adore having fresh cut flowers around the house, these two are never empty.
A: I use two techniques. Although both require a little more effort, they are both fairly successful.
1. Fill a gallon bucket with water and a few drops of dish soap before cutting the blooms. Bring your cut flowers to the bucket and slowly add the solution to each blossom. To get rid of ants, gently wave the flower in the water, then stand the ants up so they may drip dry.
2. From leftover cardboard, cut multiple circles with a diameter of 2 when just flower buds are present. Make a hole in the middle of each one. Each flower stem or group of flowers should be wrapped in cardboard, which should then have the slit taped shut. Rub petroleum jelly all over the top. Most ants that climb the stem will be caught in this trap.
Are ants permitted on 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).
Do ants help peony blossoms open?
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.

Which spice deters ants the best?
Cinnamon. What is the finest spice to use in your kitchen to get rid of ants? Cinnamon. Cinnamon is natural and non-toxic, and in addition to killing ants, its potent scent makes it effective as a repellant.
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).

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.
How can bugs on fresh flowers be removed?
A: My hydrangeas are huge and gorgeous! They are covered with bugs, and I want to bring them inside. How do I eliminate those? Am I able to keep them? I want to give it a go. Sue
A: One type of flower that need conditioning to stay attractive and prevent drooping in a container is the hydrangea. The technique used to condition them is also effective at getting rid of bugs.
When the flowers are at their turgidest, cut them early in the morning and bring them inside right away. Put them, flowers and all, in a bathtub, cooler, or sink filled with chilly water and gently submerge them. Any bugs will float to the surface after a minute. Shake off the excess water and arrange them in a vase filled with water after hydrating them in this manner for about 30 minutes. Every day or two, trim the stems again, and refresh the water. Use no water additives as these could block the vascular holes and prevent them from absorbing water.
There are several techniques for keeping them. With such big blooms, one method calls for burying them in silica, which would be challenging. Another method is glycerine, which will alter or deepen the hue, and there is always air drying, which will keep the green or pink tint but turn the white petals tan. Simply stop changing the water and let them acclimate to the drying when the stems become visible and let them air dry.
You can spray them with fixative spray from a hobby shop once they are completely dried.
I have two gerbera daisies in two pots that are allegedly winter-hardy. Given that one is on gravel and the sun will likely reflect heat, it is not too concerning that it is on the south side. One is too big to move and is on a slab in the backyard. In the event that it gets extremely cold this winter, what should I mulch with? Winter-related concerns
A: I wouldn’t invest a lot of money or effort into it. There aren’t any gerbera daisies, in my opinion, that can endure having their roots frozen. Do you know the name of the species? No matter how thoroughly insulated, plants must have extremely tough roots to endure overwintering outdoors in a container. You might be lucky, but thawing the soil within a container with the sun could be more advantageous than covering it in ice.
Perennial gerberas are classified as winter-hardy through zone 6B by Roberta’s Gardens, but zone 7 by the Greenhouse Plant Producer’s Association. I would be the first to admit that the zone names are merely suggestions, therefore I would give them a try but not put too much effort into it.
Q: Although cilantro is typically referred to as an annual, I have several plants that sprout anew every spring. Why do they return year after year? Glenn
A: Cilantro is a hardy annual, which means the seeds that fall can endure freezing conditions and are cold tolerant. These hardy annuals are frequently the first to sprout and start growing in March. Larkspur, love-in-a-mist, cornflowers, annual poppies, cosmos, calendula, allysum, balsam, and forget-me-nots are some more hardy annuals.
The bleeding heart I grew this spring has withered and fallen to the ground. Is it dead or will it reappear in the spring like Virginia bluebells? Additionally, I rarely succeed in keeping lobelia through the summer. It makes little difference if they are in a pot or a bed, and they look so lovely around a larger plant. Like with dianthus, I try to cut down the spent blooms, but whether I succeed or fail, by the end of July, they have turned to straw. Mary
A: Bleeding hearts do become dormant in the summer because they are semi-ephemeral. But every year they ought to return, larger and better. To make sure you don’t forget and plant bulbs over it come fall, it could be a good idea to use a decorative plant stake or label there.
Another South African plant that prefers warm, dry days and cool, dry nights is Lobelia erinus. They frequently become inoperable due to our mid- to late-summer heat and humidity. Next year, you ought to give convolvulus blue daze a shot and see how you like it.
