Do hydrangeas make you feel high?
Others choose the softer mop-head forms, like Hydrangea macrophylla, while some gardeners favor the spiky Hydrangea paniculata. Others, frequently individuals who have yellow rather than green fingertips, don’t seem to give a damn. According to French authorities, they simply enjoy smoking the petals from any old hydrangea, also known as hortensia.
In response to accusations that dozens of the wintering plants have been taken or brutally clipped over the previous few weeks, gendarme in northern France are on the trail of the “Hortensia Gang.”
Police say they are now looking into reports that children were wandering through residential and public gardens, cutting off hydrangea heads and leaves to dry, mix with tobacco, and consume as a less expensive alternative to cannabis.
Officers questioned neighborhood pharmacists as part of their investigations, and they acknowledged that the thousands of kinds of hydrangea blooms can have hallucinogenic and euphoric effects. According to experts, the outcome is comparable to that of Tetrahydrocannabinol (THC), which is present in cannabis plants.
According to the regional daily La Voix du Nord, police are looking into roughly 20 complaints of missing flowers that have been made by local gardeners, town councils, and village mayors in recent weeks.

Are hydrangeas cyanide producers?
The gloomy plants that took the worst of winter are getting ready for another season of stunning blossoms as spring approaches. Sadly, not all gorgeous flowers are made equal. Some very beautiful plants can do anything from give you headaches to make you sick or even kill you. Children under the age of six and our pets are especially susceptible to the negative effects of these dangerous plants. In order to protect you, your family, and your pets from potential harm, we have produced a list of the top 10 most hazardous plants that could grow in North America’s backyards.
Jonquils and daffodils (Narcissus spp.)
Because of their bulbs, these cheery yellow and white blossoms are frequently mistaken for onions before blossoming, but if you consume enough of them, they can be poisonous. Two poisonous substances are present in the stems, leaves, flowers, and bulb of the yellow-trumpeted daffodil. Lycorine, which can be harmful to both people and animals, is present in the daffodil’s bulb, leaves, and stems. Many flowering plants, including the amaryllis, contain the phenanthridine alkaloid known as lycorine. Although the toxicity level is low unless you consume a significant amount, the bulb is poisonous to both humans and animals in all sections. Lycorine consumption can result in symptoms such as diarrhoea, nausea, vomiting, abdominal pain, salivation, shaking, sadness, and convulsions. Lycorine is particularly toxic to dogs, cats, and horses. Human-like symptoms such as low blood pressure and heart arrhythmias may also be present.
Crystals of calcium oxalate can be found on the daffodil’s leaves and stems. When the leaves or stems are consumed, the crystals can result in instant oral discomfort or a burning feeling on the skin, as well as other symptoms like swelling and brief hoarseness. To stay away from what is often “If you come into contact with these dangerous plants, wear gloves, wash your hands, and develop lily rash.
Rhododendrons and azaleas (Narcissus spp.)
The honey produced by bees that consume rhododendron and azalea plants contains extremely high quantities of the plants’ poisonous component. Mad honey is a frequent name for the lethal honey. Ingesting “Azaleas and rhododendrons can also harm you in other ways other with crazy honey. Toxic effects may result from eating the plants’ leaves, nectar, or blooms. Low heart rate, very low blood pressure, and irregular heartbeat are all possible side effects of the toxin. Although extremely rare, humans who purposefully ate the plant have experienced severe, sometimes fatal poisoning. However, the plant is thought to have medical significance in various parts of the world. When children mistake them for honeysuckles, only minor symptoms like mouth irritation, nausea, and vomiting are typically present. Because of this, it’s crucial to watch out for kids (and pets) while they play outside and make sure they don’t consume any flowers, leaves, fruits, or seeds. Make sure to keep azaleas and rhododendrons out of the reach of youngsters and animals if they are kept indoors.
Chrysanthemum (Chrysanthemum spp.)
Are chrysanthemums harmful, you may wonder? Yes, all chrysanthemum plant components may be poisonous to canines, felines, horses, and other mammals. Since ancient times, chrysanthemums have been recognized for their toxicity. Their pesticide potential was highlighted in a Chinese pharmacopeia from the year 100 AD. The Europeans who later introduced chrysanthemum powder to the United States received the formula from the Persians in the 1800s. Few chrysanthemum species are now grown in commercial quantities solely to produce the insecticide pyrethrum. Despite having a botanical origin, pyrethrum is extremely toxic and kills a variety of insects, including beetles, aphids, and caterpillars in addition to harmful ones like pests. The size, quantity eaten, chrysanthemum species, and animal all affect how an animal will respond to its poison. Chrysanthemums can make you sick if you consume them, including vomiting, diarrhea, stomach pain, excessive salivation, rashes, or a lack of coordination, however they are rarely fatal.
Flower of the valley (Convallaria spp.)
This plant uses toxicity as a deterrent to prevent animals from eating its seeds. When consumed, the stems, leaves, tiny white blooms, and berries of lily of the valley are all exceedingly deadly. and the plant currently contains around 40 distinct cardiac glycosides. In chemical molecules known as glycosides, a sugar molecule is joined to a non-carbohydrate molecule. Cardiovascular glycosides improve the amount of blood the heart can pump by raising the calcium that is stored in and around cells. While this may sound less than appealing, there are currently available medications to treat arrhythmia and congestive heart failure made from purified cyanogenic glycoside isolated from the foxglove plant. But cardiac glycosides can wreck havoc on your digestive, circulatory, and mental systems in doses over the safe therapeutic dosage. Accidental lily of the valley eating can result in symptoms including blurred vision, breathing problems, nausea, vomiting, diarrhea, headaches, red skin rashes, excessive salivation, rapid changes in your cardiac rhythm, and even death.
Hydrangea (Hydrangea spp.)
These lovely, fluffy blossoms, which are prized for their brilliant blooming, have a sinister side. Are hydrangeas toxic to both people and dogs? The plant’s buds, flowers, and leaves all contain a substance called glycoside amygdalin. Because amygdalin can degrade to produce cyanide, it has the potential to render hydrangea deadly to dogs. It takes very huge amounts of hydrangea poisonous for a person or animal to become poisoned. It’s interesting to note that some people collect hydrangea flowers to dry and smoke for a less expensive high. Tetrahydrocannabinol (THC), which is present in cannabis plants, is similar to the symptoms induced by dried hydrangea plants in terms of its effects. The amygdalin molecule degrades to induce cyanide-like effects in the body’s cells, which is why hydrangea blossoms give off a euphoric sense. Cyanide effectively deprives cells of oxygen. Smokers of hydrangea typically experience sensations like lightheadedness, increased heart rate, and pleasure, but if they smoke enough, they may also experience digestive and respiratory problems. Though it is possible to become poisoned by hydrangea, it is vital to remember that hydrogen cyanide is also present in cigarettes. Severe gastroenteritis symptoms, a hydrangea rash, or skin irritation are all signs of hydrangea poisoning, along with frequently bloody diarrhea. The majority of specialists concur that a substantial amount of the plant would need to be ingested. Nevertheless, be cautious with hydrangeas if you have dogs or young children.
Numerous common houseplants can be harmful to kids, pets, and cats. The pothos, peace lily, caladium, oleander (very toxic! ), philodendron, dieffenbachia, English ivy, and snake plant are among the dangerous house plants. These are just a handful of the most typical ones; there are many, many more. Before bringing a new indoor plant close to your kids or pets, always do your research. Consuming these plants’ leaves, stems, or roots may result in toxicity.
Can you eat hydrangeas?
Hydrangeas can be poisonous, but seldom to the point of death. We worry about little children consuming things that could make them ill whether they have two legs or four legs. With kids, we worry about tiny toys, prescription drugs, and other things like plants. We worry more about our four-legged furry children eating our plants since they are curious animals and while many plants aren’t dangerous to them, there are still plenty that can result in serious illnesses or, sadly, death.
In addition to being poisonous to cats, dogs, and horses, hydrangeas are not edible. Due to the presence of cyanogenic glycoside, the plant is poisonous in all parts. You may experience depression, nausea, and/or diarrhea as some of the clinical symptoms. Even if they are not exhibiting any symptoms of illness, you should always seek the counsel of a veterinarian right away. Cyanide intoxication is often uncommon but can result in more stomach problems.
What flower is harmful to people?
One of the most dangerous plants in the world is the exquisite Nerium oleander, whose flowers are scarlet, magenta, or creamy white. If consumed, the entire plant—from the stem to the sap—is extremely dangerous. A health risk exists even from breathing in oleander smoke.
There have been incidents of unintentional poisoning brought on by campers roasting hotdogs and marshmallows on oleander branches. According to “The Vegetable Kingdom; or, The Structure, Classification, and Uses of Plants,” it is indeed thought that some of Napoleon’s soldiers in Spain perished when they used oleander sticks to cook meat (D. Appleton & Co., 1853). Even the honey produced by bees who used the oleander plant for nectar is deadly due to the blossom’s extreme hazard.
Toxins from the flower create an erratic heartbeat that starts out fast and then slows down to a rate that is significantly below normal until the heart completely stops beating.
Are hydrangeas that have dried toxic?
Yes, hydrangea leaves and blossoms can be dangerous whether they are fresh or dried, therefore regardless of the season, it is best to keep your pets away from the plant.
It’s best to keep your cat or dog away from hydrangeas entirely if they are young and still have a tendency to eat random garden plants.
Even though your cat or dog would only experience moderate symptoms from cyanide poisoning, they would need to consume vast amounts of the plant. Nonetheless, it is always advisable to prevent poisoning in any way possible.

Is hydrangea a hallucinogen?
The so-called psychotropic compounds, which alter brain function, are abundant and diverse in plants. For instance, the coca plant, a shrub native to the Andean foothills, has been utilized by the locals for thousands of years due to the effects of the cocaine the leaves contain. Mexican and Central American people have been using the peyote cactus for thousands of years to experience the psychedelic effects of mescaline. Many households in the East of England’s Fens in the 19th century cultivated a stand of white poppies in a corner of their gardens. These were obtained to create a “tea made from poppy heads that has traces of opium. The tea was a traditional treatment for a number of illnesses that plagued rural living in that region of the UK.
These are only three instances, but they show how inventive humans can be in identifying plants that, when consumed, have intriguing or helpful traits. Every flower or plant has been consumed or smoked by someone at some point, and if they made it through, they recorded the results.
Therefore, when I read a Guardian story last month, I was more than shocked “praise for hydrangeas that not only lauded the plant for its blooms but also mentioned how the flowers’ hallucinogenic effects had just recently been discovered. A companion story claimed that a wave of hydrangea attacks in northern France had been caused by persons who wanted to inhale the dried flowers and leaves because they have similar hallucinogenic and euphoric effects to cannabis. According to the condition of a hydrangea in my garden, which has plenty of new growth but few remaining blossoms that are dried, brown, and fairly mangy, the thieves must be after the new shoots.
I was unsure of how to interpret the story because I was unaware of the psychedelic qualities of hydrangea. While the joke seemed appropriate for April Fool’s Day, springtime hydrangea theft has been well-documented in Bavaria for more than ten years. Romanian authorities have stopped planting the shrub in parks because they are so worried about it.
My pharmacognosy textbook does not mention hydrangea, indicating that if hydrangea has any intriguing pharmacological qualities, they have been neglected. The shrub does, however, contain some unusual compounds, such as coumarins, hydrangine, and hydrangenol, but regrettably no information regarding their psychedelic qualities has been provided. It’s significant that hydrangea lacks cannabis-like substances like tetrahydrocannabinol.
So what is happening here? How does smoking hydrangea provide a high since it doesn’t appear that the plant contains any significant amounts of psychoactive chemicals? Veterinarian reports on the perils of hydrangea to dogs may provide some guidance. Apparently eating the leaves can make dogs and cats sick. This is due to cyanogenic glycosides, which are compounds found in hydrangeas and can break down into the extremely toxic compound hydrogen cyanide when metabolized. Many different plants contain cyanogenic glycosides, including some apricot and almond kernels, apple and cherry seeds, as well as some of their seeds.
Because it prevents cells from producing energy, hydrogen cyanide is extremely harmful to people. Cyanide can cause temporary side effects include headaches, vertigo, and confusion. Small amounts of hydrogen cyanide may be released when hydrangea leaves or flowers are smoked. One hydrangea joint may therefore include a small amount of cyanide, and the result, when paired with a healthy dosage of creativity, might be perceived as having cannabis-like effects. This would also match with the repeated recommendations to only smoke one hydrangea joint due to the high risk of cyanide poisoning.
In the UK, I have not come across any stories of hydrangeas being smoked, but I did come across one in 2012 about blooms being stolen in Hastings and Bexhill. It appears that the robbers afterwards sold the dried flowers to florists at a boot market. That’s what they claimed, at least.
I appreciate the insightful conversations that Dr. Ben Whalley (University of Reading) and Prof. Kurt Hostettman (University of Geneva) provided.
