Nepenthes Attenboroughii - Giant Pitcher Plant
Named after Sir David Attenborough, this large pitcher plant features a distinctive bell shape filled with fluid and upright lid, all of which is perfect to trap, drown, and kill insects and small rodents. While the jury is still out on whether this carnivorous plant actually does eat rodents, any plant with the capability to consume small animals - a capability this one has - is scary enough.

Brugmansia - Angel's Trumpets
Available in a variety of colors, in case you have a favorite color to honor en route to becoming a zombie, the angel's trumpets flower is as pretty as it is likely to make you go absolutely insane. Whether you eat the seeds, leaves, or pretty downward-facing trumpet flowers, this beast, ripe with various toxins, will cause confusion, diarrhea, hallucinations, a complete disconnect from reality, amnesia, and eventually death. Though sometimes used recreationally, in one instance, some poor misguided guy amputated a few of his own body parts (tongue and penis included!) after just one cup of Brugmansia tea. Don't do drugs, kids.

Ageratina Altissima - White Snakeroot
Found randomly in the woods, this plant is no joke. Say a cow eats it. The plant won't just hurt the animal, but will also poison the milk and meat of the cow, and any human who consumes either will get horribly sick. For real, thousands have died from consuming the milk from cows who gobbled up this white flower, including Nancy Hanks Lincoln, mother of Abraham Lincoln.

Aconitum Napellus - Monkshood
From the "probably growing in a garden or wooded area close to your home right now" category, this pretty, bluish-purple flower is often dried or just planted for decoration because it looks snazzy. The plant, however, also doubles as a highly lethal cardiac poison - so much so that once upon a time, it was used on spears and arrows to kill enemies and prey.

Cephalotus Follicularis - Australian Pitcher Plant
This plant, which is as ugly as it is dangerous, looks like a pile of moccasins (and is affectionately nicknamed the moccasin plant), but don't go sticking your feet in this killer. The Cephalotus follicularis has several small pitchers replete with spikes to trap and drown any prey that is unfortunate enough to crawl inside. If that wasn't enough, it also has clear cells inside, which confuse victims while they are being digested.

Hippomane Mancinella - Little Apple of Death
Though this killer plant doesn't have any scary traps or mechanisms to ensnare prey, it will, quite easily, kill you, just for coming close to it. Brush up against this beast, and you will enjoy a horrible allergic skin infection. Ingest one of the delicious little apples ("manzanillas"), and you can find yourself the proud new owner of nausea, vomiting, diarrhea, and seizures - if one of the tree's many toxins don't kill you first.
