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.
Are hydrangeas toxic to humans?
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.
A hydrangea is it safe to touch?
The hydrangea plant, Hydrangea Macrophylla in its botanical name, is poisonous to humans but typically not fatal.
Toxic Components:
Symptoms:
gastrointestinal discomfort, nausea, vomiting, sweating, diarrhea, lethargic behavior, and, in more acute cases, more serious issues like labored breathing, seizures, and coma.
Treatment:
Doctors will work to replenish your fluids, make breathing easier for you, and give you medication to restore your regular heartbeat.
What causes hydrangeas to be toxic?
The therapeutic index of hydroxyurea, an exceedingly toxic medication, is quite low. Because it prevents DNA synthesis, hydroxyurea can be extremely toxic and cause myelosuppression. Additionally, red blood cells may develop megaloblastic properties if DNA synthesis is inhibited without affecting RNA production.
Canine hydrangea plants be toxic?
Signs of Pet Hydrangea Poisoning Ingesting enough hydrangea leaves, blooms, or buds can cause vomiting and diarrhea in dogs and cats. Lethargy, despair, and bewilderment may result from severe hydrangea poisoning.
Around children, are hydrangeas safe?
The wonderful Hydrangea is a flowering plant that brings a sense of romanticism to the yard with its striking clusters of blue, purple, pink, and white blossoms. Unfortunately, the entire plant—including the flower buds—is highly hazardous to both children and pets.
There are residues of cyanide in every part of the hydrangea. Breathing difficulties, fainting, a fast heartbeat, and disorientation could result from accidental intake. Poisoning that is severe enough to cause convulsions and death is also possible.
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.
Can hydrangea be smoked?
One, it’s not very ethical to steal someone else’s plants or those from a public garden or arboretum. In order for others to enjoy them, people spend time caring for them. Secondly, some steal them to get high. Seriously? Do you smoke dried hydrangea to obtain a high similar to marijuana? Really. I remember hearing about this many years ago. The process went like this:
“Dude, I smoked some dried hydrangea blossoms. It was deadly. I nearly passed out from being so intoxicated.
But now it’s returned. It’s possible that we’re more conscious of it now because of social media’s growth and 24-hour news cycles, or it’s also possible that people really are that stupid and our gene pool is getting contaminated. Why, then, is it so stupid? Start with hydrangeas themselves so to speak.
There are over 70 species of hydrangea in the genus, and they are found almost everywhere. The deciduous hydrangeas, which are native to Asia and the Americas, often have a bush-like shape and can reach heights of up to 3 meters. Although they appear in a variety of hues, their characteristic pop-pom-like flower heads are most frequently seen in blue and white (from my experience here in the US, at least). An unprofessional tip: Having a more acidic soil, approximately pH 6, will intensify the blue hue. This can be done in part by adding used coffee grounds to the soil.
Here comes the dangerous phase. You’re reading this because of it, right? The glycoside amygdalin can be found in the buds, flowers, and leaves. The chemical cyanide, which was once utilized in gas chambers and was the poison of choice for many villains in literature, film, and real life, can be produced by breaking down amygdalin in a variety of methods. The toxic nature of raw almonds and peach pits is also attributed to amygdalin.
Cytochrome c oxidase inhibition, which results in histotoxic hypoxia, causes acute cyanide poisoning. Your cells are oxygen-starved, to put it in less geeky terms. It’s horrible, I assure you. Inadequate quantities of cyanide inhaled can result in coma, cardiac arrest, or death within minutes. Symptoms of non-lethal yet toxic doses include loss of consciousness, exhaustion, breathing problems, and lightheadedness. You are denying yourself of oxygen, which is the source of this.
In fact, these kinds of poisonings happen frequently. Many plastics and polyurethanes burn, releasing cyanide gas that can harm both the victims of the fire and first responders. Cyanide can be found in theaters, factories, mobile homes, and even while burning plastic outside. Additionally, some have attempted to utilize it for terrorism and mass murder due to how lethal it is. Scumbags.
Returning to hydrangeas now By way of amygdalin, smoking dried hydrangea leaves can potentially provide a sub-lethal amount of cyanide that would deprive your body of oxygen and leave you feeling “high” and lightheaded. I prefer to refer to it as “low,” as in low oxygen. Low IQ. Low chance of finding some marijuana. Is there a Darwin Award category for this kind of behavior? Can we have one please?
The act of taking someone’s hydrangeas irritates me. Hell, I would have given them my own if I had realized they were that desperate for them. Last year, I tore three sizable ones out of my front yard.

If my cat eats a hydrangea, what happens?
Nothing better embodies summer than a vase filled with recently gathered hydrangeas from the garden. Although those large, spectacular blooms make for stunning cut flowers, you should exercise caution if you have a cat in the house or garden since hydrangeas can be deadly to cats.
How do cats get hydrangea poisoning?
Any component of the hydrangea plant can poison cats if they eat it. Cyanogenic glycoside is the name of the hydrangea’s poisonous substance. The poison is present in the flowers, leaves, buds, and stalks, however it is concentrated primarily in the buds and leaves.
What are the symptoms of hydrangea poisoning in cats?
The most typical signs of hydrangea poisoning in cats are the same as in dogs:
- reduced appetite
- Vomiting
- Diarrhea
- hurting belly
- Depression
What should owners do if they suspect their cat has consumed hydrangeas?
You should probably call your veterinarian and keep an eye out for symptoms of disease if your cat has eaten any portion of some hydrangea petals. Fortunately, hydrangea poisoning instances usually don’t go very bad, according to Dr. Michelle Burch, a veterinarian with SafeHounds Pet Insurance.
Your cat could need supportive treatment from the veterinarian if the plant poison makes her ill. That may indicate the need for fluids, drugs, or pain relief.
Your cat may also require a bland food while she is healing, such as cooked chicken, white rice, or plain yogurt.
How to prevent poisoning
If your cat frequents the hydrangeas in your yard, you should find a technique to keep her away from the flowers as much as you can. Dr. Burch advises scattering thorny vines, branches, and shells throughout the yard because dogs and cats don’t like to step on them. There are a few different strategies you can attempt.
Sprays of botanical oils You can use a variety of items as a non-toxic botanical oil spray to treat the margins of your garden or plants. According to Dr. Burch, the fragrance of the plant oils is repulsive to dogs and cats, acting as a deterrent.
Motion-Detecting Sprinkler On the perimeter of your garden, you can place a motion-activated sprinkler to deter animals. “The sprinkler will blast an unsuspecting invader in that direction when it detects motion,” claims Dr. Burch.
Sonic Discouragement To detect movement, ultrasonic deterrents can also be deployed. They may also use light to frighten dogs away from specific sections of the yard or garden. They do this by emitting an ultrasonic sound.
Take precautions when cultivating, smelling, and enjoying hydrangeas this summer if you have a cat who enjoys munching on things like flowers and foliage, regardless of the strategy you use to keep cats and hydrangeas apart.
