Flowers are nature’s way of tricking insects into helping plants have sex, and as a side effect, humans have something to make their gardens look prettier. There are about 350,000 species of flowering plant, and most of them are innocent souls. But a heaping handful of them are vicious killers with zero remorse


Kalmia Latifolia
Kalmia latifolia, more commonly known as mountain laurel, produces delicate pink and white flowers in the late spring. It’s the state flower of both Pennsylvania and Connecticut, and it grows just about everywhere in the eastern United States. It’s gorgeous, but underneath that dainty exterior beats the heart of a murderer. The two main toxins in Kalmia latifolia are andromedotoxin and arbutin, but it’s the first one that you need to worry about. Andromedotoxin simultaneously causes part of the heart to beat quickly and part to beat dangerously slowly. In healthy people, the heart has a natural gate that blocks half of the electrical pulses coming to the organ. The toxin induces Wolff-Parkinson-White (WPW) syndrome, which disrupts that gate, letting all the pulses reach your heart. The result? Sudden cardiac death.But that only happens with large doses. In smaller doses, you can expect to start with a lot of vomiting, after which every hole in your head will leak its fluids down your face. About an hour later, your breathing will slow down, you’ll lose the ability to use your muscles, and you’ll slip into a coma and die. The terrifying part is that you don’t have to eat the flowers—honey from bees that have visited Kalmia latifolia contains all the toxic properties of the flower itself. The Greeks called it “mad honey,” and they used it to defeat Xenophon of Athens in 400 B.C.



Veratrum
Found on nearly every mountain in the Northern Hemisphere, Veratrum species put out gorgeous spiral clusters of white, heart-shaped flowers. The plant is commonly grown for ornamental purposes because even the leaves look pretty, and in the wild, it’s commonly confused with garlic. But pretty or not, every piece of this plant, from the roots to the pistils, is lethally toxic.The first symptom of Veratrum poisoning is violent stomach cramping, which usually starts about 30 minutes after ingestion. As the toxins absorb into the bloodstream, they make a beeline for the sodium ion channels. Sodium ion channels act like gates to allow sodium to flow through nerves, triggering an action. For example, the opening of sodium ion channels in muscle cells starts the process that leads to a muscle contraction.When Veratrum toxins hit the sodium ion channels, they open the floodgates, forcing the channels to fire continuously. The body doesn’t know what to do with this, so the heart begins to alternately slow and speed up. Muscles all over the body convulse. Eventually, the toxin either causes a heart attack or a coma. It’s believed that this is the poison that killed Alexander the Great.


Adenium Obesum
Native to Africa, Adenium obesum has been used as a spear poison by tribes for centuries. The desert rose, as the preparation is called, is made by boiling the plant for 12 hours before removing all the plant matter and letting the liquid evaporate. The resulting goo is a highly concentrated poison. It’s so toxic that just a bit of the poison from a spears or arrows brings down large game before they can run 2 kilometers (1.2 mi), so hunters can stay on their trail while they gradually bite the dust.This specific plant has been used by tribes all over Africa to kill animals as large as elephants, and now that we’ve studied it, we know why. The plant contains a chemical called ouabain, which causes almost immediate respiratory failure at high doses. Another flower in the Apocynaceae family grows in the same region, and hunters often use it in conjunction with Adenium. It also contains ouabain, and it turns out that humans aren’t the only African natives using its killing power—the African crested rat will chew the flower’s bark and lick his hair with the toxins, turning itself into a scurrying ball of unexpected death.


Oenanthe Crocata
In 2002, eight tourists in Argyll, Scotland decided to forage some choice water parsnips from a nearby stream. Prize in hand, they returned home and put them in a curry dish. The next day, four of them were in the hospital. What they’d thought was water parsnip was actually Oenanthe crocata, or hemlock water dropwort. The plant has mortality rate of up to 70 percent, so the group was lucky nobody died.Hemlock water dropwort has an interesting property. It’s lethal, sure. But the killer toxin, oenanthotoxin, relaxes the muscles around your lips and forces you to smile, even when you’re in the throes of fatal convulsions. The plant has been used in Greece since at least the eighth century B.C., when Homer coined the term “sardonic grin” to describe the grisly smile adorning the faces of water dropwort victims.
