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

Who would have thought that a flower could ruin your holiday? Strange as it may sound, some seemingly harmless plants can be deadly. To help keep you out of the hospital bed on your next trip, we’ve sussed out the world’s most attractive but dangerous flowers.

1. Autumn Crocus
This is one flower you don’t want to encounter on your next break. One of the most endangered plants in the world, Autumn Crocus is also the most poisonous. It contains colchicine, a drug used to treat gout. Unlike other toxins found in some flowers, colchicine has no antidote. Autumn Crocus poisoning leads to reduced blood pressure and cardiac arrest.

2. Oleander
One flower that gives Autumn Cross a good run for its money in the danger department is Oleander. Known as one of the most poisonous plants on earth, it is often used in suicidal cases around southern India. Its numerous toxic compounds can affect the nervous, digestive and cardiovascular systems, all at the same time.

3. Rhododendron
Step away from the Rhododendron; this popular evergreen shrub with its large, beautiful blooms has been known for its toxicity since ancient times. It contains a toxin called Andromeda which causes nausea, severe pains, paralysis and even death. Azaleas, members of the same plant-family are also poisonous.

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

5. Belladonna
If you’re holidaying in the Western Hemisphere, keep an eye out for the potentially-lethal Belladonna. The entire plant is harmful, but its good-looking berries pose the most danger, especially to kids. Symptoms of Belladona, or Deadly Nightshade poisoning are dilated pupils, blurred vision, headaches, hallucinations, delirium and convulsions.

6. Daphne
It sounds harmless enough, but Daphne (also known as Lady Laurel or Paradise Plant) is deadly. Standing at 1-1.5 meters tall, this shrub is 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 two powerful toxins that cause stomach aches, headaches, diarrhoea, delirium and convulsions.

7. Lily of the Valley
Just like the Daphne, Lily of the Valley may look beautiful and harmless, but it’s poisonous. Eating one or two of the plant’s bell-shaped flowers won’t hurt you very much, especially if you’re an adult. But eaten in large quantities, it causes pain in the mouth, nausea, vomiting, cramps and diarrhoea. People with heart conditions should be most careful since the toxins cause heartbeats to slow down or become irregular.

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.

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:

Norah says on August 3rd, 2012 at 5:15 pm:

Your illustration for Deadly Nightshade is incorrect. You have shown Woody Nightshade which also is poisonous but not as toxic as Deadly Nightshade.

Caroline says on January 13th, 2013 at 7:16 pm:
