World’s most poisonous plant has driven people to suicide — like the man who accidentally used the leaves as toilet paper and wound up shooting himself

Don’t put your thumb on this green.

Many gardeners might not be aware of the lethal plant thought to be the most toxic in the world called the Gympie-Gympie.

The ghoulish greenery sports tiny hair-like needles full of poison and has a sting so painful it has driven some people to contemplate suicide, The Mirror reported.

The excruciating sensation of coming into contact with the hair of the Gympie-Gympie, which can grow up to 32 feet tall, feels both like electrocution and burning — a sensation that can last for weeks, or even months.

In some extreme instances, the persistent pain has led sufferers to take their own lives.

Originating from Australia, the plant’s deadly effects were discovered in 1866, after a road surveyor’s horse suffered a fatal sting.

Another harrowing case was documented when an Australian soldier endured weeks of ineffective treatments following a painful encounter with the needles during World War II. The soldier eventually succumbed to madness.

Another reported incident involved a person who used the leaves as toilet paper, not realizing what plant he was picking up. This event supposedly drove him to shoot himself.

The Australian stinging tree, dubbed Dendrocnide moroides by scientists, was put on public display at a botanical garden in the UK last year.

Due to the plant’s high-risk nature, it is kept behind safety glass and cared for only by a designated horticulturalist.

As it turns out, the Gympie-Gympie isn’t the only piece of greenery to be wary of.

In October, a poisonous plant called “baneberry” started prompting warnings from park rangers who are urging the public not to consume the toxic vegetation.

“Is that plant looking at me?” the National Park Service wrote on Facebook at the time alongside a photo of a white baneberry plant, whose fruits resemble eyeballs.

“Actaea pachypoda, the white baneberry or doll’s-eyes, is a species of flowering plant of the family Ranunculaceae,” the agency explained. 

“The plant’s most striking feature is its fruit, a 1 cm diameter white berry, whose size, shape, and black stigma scar give the species the name, ‘doll’s eyes.’”

The organization quipped: “Did it just blink?”

“Well I have to say that if ever there was a plant I would not even touch, never mind eat, this would be it,” quipped one Facebook user.

“This plant just screams ‘Don’t Eat Me!’ Why any human would think such a grotesque thing was palatable is beyond me,” another exclaimed.
