The 7 Most Beautiful-But-Deadly Flowers in the World

Beautiful as they may be, some flowers are much more than they appear to be. Believe it or not, these seemingly harmless plants can really ruin your vacation. To help you know what flowers to stay away from on your trips, we’ve come up with a list of the world’s most attractive but dangerous flowers:

7. Daphne

Also known as lady laurel or paradise plant, Daphne is a 1-1.5 meters tall shrub, usually grown for its scented flowers. All parts of the plant are poisonous, but the greatest concentrations are in the sap and berries.

Daphne contains mezerine and daphnin, two powerful toxins that cause stomach aches, headaches, diarrhea, delirium and convulsions. If Daphne berries are consumed, the victim might fall into a coma and even die.

6. Lily of the Valley

Just like the Daphne, Lily of the Valley may look beautiful and harmless, but it is entirely poisonous. Eating one or two of the plant’s bell-shaped flowers won’t hurt you very much, especially if you’re an adult.

Eaten in large quantities, Lily of the Valley causes pain in the mouth, nausea, vomiting, cramps and diarrhoea. People with heart conditions should be most careful since the toxins cause the heartbeats to slow down or become irregular.

5. Belladonna

Known as one of the most poisonous plants in the Western hemisphere, Belladonna contains potentially lethal tropane alkaloids. The entire plant is harmful, but its good-looking berries pose the most danger, especially to kids.

The symptoms of Belladona, or Deadly Nightshade poisoning are dilated pupils, blurred vision, headaches, hallucinations, delirium and convulsions. Atropine, the toxin contained by Belladona, can kill a person by disrupting the nervous system’s ability to regulate breathing, sweating and heart rate.

4. Angel’s Trumpet

Despite its name, there’s something very evil about this plant. The toxins it contains can be fatal to humans and a number of animals. Known as a powerful hallucinogen, Angel’s Trumpet should not be used for recreational purposes, since the risk of an overdose is very high.

Angel’s Trumpet plants contain a variable amount of tropane alkaloids, like atropine and scopolamine, and it is used in shamanic rituals by indigenous tribes in western Amazonia.

3. Rhododendron

This popular evergreen shrub, featuring large, beautiful blooms, has been known for its toxicity since ancient times. Xenophon recorded the odd behavior of a group of Greek soldiers who had eaten honey from rhododendron flowers.

Rhododendron contains andromedatoxin which causes nausea, severe pains, paralysis and even death. Azaleas, members of the same plant-family as rhododendron, are also poisonous.

2. Oleander

Oleander is known as one of the most poisonous plants on Earth, often used in suicidal cases around southern India. The numerous toxic compounds contained in the entire Oleander plant, including oleandrin and neriine, affect the nervous, digestive and cardiovascular systems, all at the same time.

Oleander poisoning leads to drowsiness, tremors, seizures, coma and even death. The plant’s sap causes skin irritation and severe eye inflammation.

1. Autumn crocus

One of the most endangered plants in the world, Autumn crocus is also probably the most poisonous. It contains colchicine, a deadly drug used effectively in the treatment for gout. Unlike other toxins found in the flowers above, colchicine, an arsenic-like poison has no antidote.

Autumn crocus poisoning leads to reduced blood pressure and cardiac arrest.

I had found a few of the “belladonna” flowers which are wild. Several friends have told me it’s “shooting star” aka Dodecatheon http://bit.ly/AETFs I hope I’m not wrong because I picked a lot of them that day…

The picture you have for deadly nightshade is Solanum (bitter nightshade) which is not particularly poisonous. It grows as a common vine, but is easily pulled out although it does spread by underground runners so it can take a lot of pulling. It also is very stinky when the stems or leaves are broken. Deadly nightshade is Atropa belladona, the flower is a pale purple to pinkish and bell shaped. The leaves are not split into 3 sections and it doesn’t grow as a vine. Dodecatheon flowers are shaped like this picture, but it grows from a basal clump of leaves and the flowers are not the intense purple and yellow of the nightshade.

Just so you know, you posted photos of the incorrect nightshade. The one above, commonly called “woody nightshade” or sometimes “bittersweet,” is solanum dulcamara; “deadly nightshade” is atropa belladonna. They look quite different, so I would strongly suggest posting new photos for the benefit — and safety — of all your viewers!

Deadly nightshade has bell-shaped flowers with five petals which have a slightly more magenta and green-tinged hue than the rich violet of woody nightshade. The blossom is about the right size to wear on your fingertip. Deadly nightshade plants grow as a sort of soft-stemmed shrub, up to 1.5 metres tall, and they have large, wide teardrop-shaped leaves with no teeth or lobes. Deadly nightshade berries are about 1 cm wide, and grow individually at the end of separate stalks, nestled in the sepals. The berries are black when ripe, but can at times be about the right size and colour to be mistaken for blueberries by those unfamiliar with the plants. Woody nightshade berries are tiny, oval, and don’t resemble most edible berries. They start out green, then turn yellow, orange, and finally a bright red.

Woody nightshade *is* poisonous, but one would have to consume much, much more of the plant to be affected, and it is seldom fatal. It’s more likely to cause some stomach upset and diarrhea. On the other hand, one leaf or 5 berries of deadly nightshade could kill a grown man.

wow those are so pretty but fuckin dangerous

Benji says on July 4th, 2010 at 8:01 am:

Yes, your photos for deadly nightshade are incorrect. They are of woody nightshade or bittersweet nightshade. Solanum dulcamara. It is much less poisonous than deadly nightshade.

flowers says on July 4th, 2010 at 10:48 pm:

flower is to connet two people

Mesmerized By Life says on October 14th, 2010 at 3:53 pm:

My dog ate the berries of the woody nightshade shown and suffered all the symptoms stated. I feel quite lucky that he survived, had it been a small child the outcome could have been quite grim. I suggest we make ourselves aware of both of these nightshades. Thanks for the info!

Lunnal says on November 7th, 2010 at 5:04 am:

Hi, Yes the Nigtshade you have pictured here is called “Woody Nightshade” and the green berries are quite poisonous! When they turn red not so much.

Erikson says on November 18th, 2010 at 9:58 pm:
