Can Wisteria Kill You

Wisteria has two sides, those who consider it an invasive weed and those who enjoy eating its delectable, aromatic blossoms.

That duality fits with the Wisteria, which is also known as Wistaria. There are two accounts on how the genus obtained its name: Some claim that it was called in honor of the abolitionist, physician, and anatomist Dr. Caspar Wistar (1761–1818). Some claim that it was named after Charles Jones Wister Sr., whose father, Daniel, financed for the Empress of China’s trip that transported a wisteria vine from China to North America. The Empress of China, a former privateer constructed in 1783, was the first vessel to depart from the newly established United States for China. It also brought the first American ambassador to China. The entire journey took 14 months. They were unaware that Wisteria had already arrived.

Edibility is the latest personality of Wiseria. The plant’s flowers can be eaten fresh or cooked. The remainder of the plant itself is poisonous. In actuality, two uncooked seeds are all it takes to kill a child. That is typical for a pea family member, whose members can range from edible to lethal.

Wisteria sinsensis, often known as the Chinese Wisteria or the Wisteria that rode along with the Empress of China, is one of the eight to ten species of wisteria that are most frequently found. It is a robust, quick-growing plant that fixes its own nitrogen and doesn’t require fertilizer. In actuality, both pruning and abuse enhance flowering. It is regarded as an invasive species in some places and can live for at least 144 years (as of 2014). From Maine to Florida and as far west as Arkansas, it has become naturalized. Since its introduction in 1816, not bad.

While the ship that brought the Wisteria back from China may have been named after its underwriter, Wiseria frutescens is a native Wisteria in North America. Of the Wisteria family, its flowers are the smallest. The American Wisteria, W. frutescens, has smooth rather than velvety seed pods and unscented flowers. From Virginia to Louisiana and on down to Florida, it is present. If you discover smooth seed pods but just faintly fragrant blossoms, you have the native Kentucky wisteria, also known as W. macostachya (found in Louisiana, Texas, Kentucky, Illinois, Missouri and Oklahoma.) The Japanese Wisteria floribunda adds to the complexity. It is an escaped prisoner in the southern US.

Now, some limitations: Young W. floribunda leaves, also known as W. macrobotrys and W. multijuga, are fried and consumed in Japan, while the blossoms are blanched. Toasted seeds are used. Since I haven’t tried it, I can’t suggest it. This is valid for Wisteria venusta, often known as Silky Wisteria. It has counterclockwise twisted, 9–13 leaflet, vine up to 25 feet long, white flower clusters that are six inches long. Young seeds and leaves were reportedly fried. Yellow splotch on the blossoms, often known as Wisteria brachybotrys. The blossoms of the Wisteria villosa and the seeds and leaves of the Wisteria japonica have both been consumed as famine food.

We practically know who Wisteria was named after, as was already mentioned. You pronounce it Wiss-STEER-ree-ah. And although it’s not really relevant, the word Wistar, which means “steward of the food supply,” is derived from the Germanic and Old English. Frutescens (froo-TESS-ens), Floribunda (flor-ih-BUN-duh), and macrostachya (mak-ro-STAY-kee uh, or mak-ro-STAK, yuh), all refer to shrubby or bushy plant species, respectively. Venusta (ven-NUSS-tus, meaning attractive and lovely. Since it will cling to almost anything in its path, wisteria is seen as a pest. When other vegetation is involved, this also means their demise. Some can reach 100 feet in length and 15 inches in diameter.

Can wisteria cause human death?

A deciduous ornamental vine called wisteria may climb trees up to 60 feet into the canopy. It can live for 50 years or longer, and it appears that the only thing limiting its development is the height of the trees. Wisteria’s leaves, fruits, and seeds are poisonous to humans and many animal species, and they can deform or destroy attractive trees. Japanese wisteria and Chinese wisteria are two kinds that can be found in the United States, along with their hybrids. While Chinese wisteria vines thread counterclockwise around their host trees, Japanese wisteria vines twine in the other direction. Other than that, biological traits and management options are comparable between Chinese and Japanese wisteria.

Origin: As suggested by their common names, Chinese wisteria is indigenous to China, whilst Japanese wisteria is indigenous to Japan. Around 1830, both were brought to North America as exotic ornamentals. Since then, wisteria has been widely planted in the southern United States as a beautiful element for gardens, walls, gazebos, and porches. The majority of infestations in undeveloped regions are brought on by escapes from landscaping plants.


Young wisteria stems are thin, thickly pubescent, and brown. As they grow older, they smooth out and produce a tight, gray to white bark. Older plants have a maximum diameter of 15 inches.

Up to 12 inches long, pinnately complex leaves are alternately arranged. Each leaf has a maximum of 7–13 (Chinese) or 13–19 (Japanese) leaflets, each of which has wavy borders and a tapering tip.

Flowers hang in 10–20 inch long, fragrant, and ostentatious bunches. Blooms can be lavender, pink, white, or violet blue and bloom in succession from the base to the tip.

The pods, which resemble flattened beans and are velvety brown in color and may last for long time on the vines, contain the seeds.

Although the seeds are viable in the right circumstances, wisteria mainly spreads by vegetative growth. It produces stolons, which are above-ground stems that stretch out horizontally across the ground and sprout new roots and shoots at their nodes.

Wisteria is currently widespread throughout the eastern United States. Numerous soil, moisture, and shade conditions are acceptable to it. Infestations are frequently seen in urban settings, riparian zones, disturbed sites, roadside ditches, and woodland borders. Trees, bushes, and man-made buildings can all be climbed by vines.

Problem: By girdling and destroying natural vegetation, wisteria displaces it. The tough, woody vines firmly entwine around the trunks and branches of the host trees before slicing through the bark and girdling the tree. On the ground, new vines that grow from seeds or rootstocks produce thickets that smother and shade out native plants and obstruct the growth of natural plant communities. As a result of this process, the canopy develops gaps and more sunlight penetrates the forest floor, altering the structure of the forest. Although some native plants may have a brief advantage, this usually only encourages the prodigious development and spread of the many wisteria seedlings. Once wisteria has grown, it can be very challenging to get rid of it.

Management: The best results for wisteria control and minimizing effects on native species will come from combining human, mechanical, and chemical control methods. A concentrated systemic herbicide should be applied to the cut surfaces of the rooted living portions of vines that are climbing up trees or structures after they have been pruned as close to the root collar as feasible. Cutting needs to start early in the growth season and continue regularly until the fall since wisteria will keep growing until its root stores are depleted. Even if they are cut at the base, vines encircling trees should be completely eradicated since they will continue to girdle the tree.

PESTICIDES SHOULD ALWAYS BE USED SMARTLY, SO ALWAYS READ THE WHOLE PESTICIDE LABEL CAREFULLY, COMPLY WITH ALL MIXING AND APPLICATION INSTRUCTIONS, AND WEAR ALL RE For any further pesticide use rules, limits, or recommendations, get in touch with your state’s department of agriculture.

Is it harmful to touch wisteria?

Wisteria Wisteria has a seductive charm, but did you know that it is only mildly harmful to cats and dogs? Its seeds, in particular, are harmful in every way.


Wisteria plants are poisonous in all parts, but the pods and seeds are particularly dangerous. Even while severe poisonings are uncommon, it has been documented that exposure to as little as two seeds might have detrimental consequences. Oral burning, stomach ache, diarrhea, and vomiting are among the symptoms. In 1.53.5 hours, digestive problems may start to manifest. Weakness, syncope, vertigo, and confusion have all been reported. It has also been observed that white blood cells have increased.

Usually, symptoms go away in 24 to 48 hours, but in one case, the vertigo and chronic weakness persisted for 57 days. In hazardous exposures, lectins do not have the mitogenic and blood coagulation effects that are observed. Headaches are reported to occur when this plant’s smoke is inhaled.

Are the wisteria blossoms toxic?

Wisteria, also known as wistaria or wysteria, is a climbing vine related to the blooming pea plant that may reach heights of 60 feet and a width of 30 feet. The flowers are white, pink, violet, or purple and grow in flowing clusters. The most toxic parts of the plant, which resemble pea pods and contain high levels of the poisons lectin and wisterin, are the seedpods. If seed pods or seeds are devoured, as well as a significant number of blooms or foliage, both of these can be fatal. Even if your dog shows no symptoms, you should contact your veterinarian or seek veterinary care as soon as you can because there is no acute discomfort or unpleasant taste and your dog may continue to eat until a deadly amount is swallowed.

A group of flowering vines known as wisteria are as venomous as they are attractive. They are renowned for their cascading torrent of hanging blossoms, but if even a few seed pods are consumed, they are toxic. Small animal and child fatalities have been documented numerous times over the years. Wisteria has two harmful components: lectin and wisterin glycoside. Both of these can be lethal, but the seed pods and the seeds themselves are the most dangerous because they have the highest concentrations of lectin and wisterin glycoside. Lectin causes harmful blood clotting, blood cell clumping, and the possibility of a stroke. The extreme diarrhea and vomiting that the wisterin glycoside can cause can lead to death by dehydration.

Do demons fear wisteria?

Wisteria blooms are introduced in “Demon Slayer: Kimetsu no Yaiba’s” fourth episode, which also emphasizes how potently medicinal they are, particularly as a poison. The scent of the wisteria flower, when concentrated, works wonders to ward off demons. When used on typical, higher-ranking demons, the flower can at least paralyze them. It works especially well against low-ranking demons.

Demons like to stay away from wisteria flowers as much as possible due of the threat the plants pose. This is precisely why the Demon Slayer Corps’ headquarters are surrounded by flowers; it protects them from danger (most of the time). Wisteria is also used to inscribe the ranks of the Demon Slayer Corp members into the hands of demon slayers, therefore the flower’s importance extends farther for them. The flower serves as an effective symbol for the business.

As of this writing (May 2021), only one season of “Demon Slayer: Kimetsu no Yaiba” has been broadcast, but future plotlines in the manga series indicate that wisteria blooms will play a significant role in the mythology as a whole. Fans should be delighted to return to the demon realm sometime in 2021 since there has already been a sequel movie, “Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train,” and a second season of the anime has already been confirmed. Be sure to keep some wisteria blooms on hand, though.

Why is wisteria feared by demons?

We learned that wisteria deters demons in a recentish episode of Demon Slayer (uncertain when this will be published). This piqued my interest. I was aware of the name, of course, but the episode made me realize that I was unaware of what wisteria actually is. not to mention why they would make a strong all-around defense. I thus did as I normally do and turned to my trusted friend Google.

The first thing I discovered is that wisteria are incredibly lovely:

Since Quebec’s weather can be rather fickle and only the hardiest plants can survive, I doubt that we see the flower very often. However, as I shall discuss a little later, that might not be be the problem. By entering “wisteria” and “devil” together in the search field, I discovered a second thing: there isn’t a clear connection between the two. More research was required!

In actuality, wisteria is an Asian plant species that belongs to the pea family. Though I believe it has spread to the nearby areas as well, it appears to have its natural origins in China and Japan. It was introduced to Europe and America some time ago, and now various American versions are also successful in the US.

The plant’s traditional meaning comes from Chinese and Japanese civilizations. The flower has also been utilized in Kabuki theater as a symbol of love, sensuality, support, sensitivity, bliss, and tenderness. It is more frequently linked to luck, youth, and births. I suppose all these loving and compassionate relationships may be seen as the opposite of demons, but I’m not sure that’s the whole story.

In reality, the bloom is quite resilient, and individual specimens can survive for hundreds of years. The oldest live one is currently thought to be in Japan and has been extant for more than 1200 years. It is therefore not strange that it is linked to immortality. Although there are trees that outlive flowers much longer, the endurance of flowers is still rather remarkable.

We can draw a few parallels between this and the Demons. I haven’t read the manga, and the anime hasn’t provided us with a lot of information on the demon lore thus far, so I’m just treating them like vampires. mostly because they are killed by the sun, which is typically associated with vampires even though their behavior is very similar to that of zombies. In essence, I’m thinking that demons do not age and do not pass away naturally, but the anime has not explicitly stated this.

Wisteria is also a rather combative plant. You must frequently trim them back when introducing them into new surroundings or else they risk taking over and suffocating the nearby plants.

Thus, rather than being hostile to demons, they are comparable to them in many ways. a persistent and perhaps deadly presence that encroaches on other living things.

In actuality, there is a straightforward canon explanation for demons’ aversion to flowers. You could assume that the fact that Demons want to stay away from them so desperately is because of the plant that can be used to create a poison that is fatal to them. They want to cross the grove so badly that they would rather starve to death on a remote mountain. I don’t think the tale goes any further than that.

But I want to add my headcanon to it since we like to find relevance when there isn’t actually any. Find a tiny reason why the author would have picked that particular flower over the dozens of dangerous plants that were available. Furthermore, I don’t believe the conventional interpretations are enough. Instead, there was a fusion of those symbols and the plant’s organic behavior.

They resemble devils if you consider wisteria as a symbol of rebirth and immortality and add that to their lengthy lifespans and predatory nature. Both prey on others in search of immortality, but one is a sign of impending death, while the other is the promise of brand-new life. The other, which is connected with sunshine, conveys our ideal of freshness and beauty while conjuring images of decay, rot, and gloom. They are conceptually similar to funhouse mirror representations of one another.

Okay, so this might be a bit of a stretch, but I like this interpretation of Wisteria’s role in the Demon Slayer mythos. What do you think of the series, if you guys watch it? Am I making any sense here? Perhaps there were hints in the episode that I missed (or simply put, I’m slow sometimes), which would have led us to believe the exact opposite. I’d be interested to hear about any conspiracy theories you may have.
