Tonight at the Denver Botanical Gardens, writer Amy Stewart will be presenting a history of killer plants of the very real variety. While that's all well and good, we prefer to keep our deadly botanical assassins in the realm of the fiction so we can still sleep through the night. Killer plants have long been a staple of fiction in all kinds of media, so to celebrate, we've tallied up our favorite plantae atrocities on video.10. The Navy vs. The Night Monsters
First off, this movie is absolutely terrible, so don't bother actually watching it, unless, like us, you have a weird fascination with anything that takes place in Antarctica. As the story goes, a scientific exhibition to the great white South unearths a killer tree that secretes acid and comes alive at night. If it sounds stupid, you're probably on the right track.9. The Day of the Triffids
In the original novel, the Triffids are experimental plants that are capable of moving around and killing people. In the film, they're alien-plants, which happens to be a big pain in the ass because, when they came down to earth, most of the world's population was busy watching a meteorite show that ended up causing blindness. It's a classic '60s horror movie in every respect and well worth your time.8. Piranha Plants
Probably one of the most iconic killer plants in history, the piranha plants from the Mario series of videogames have a special place in our hearts, because they were one of the biggest pains in the ass to deal with in the games when we were kids. They just popped up out of pipes and spit fire at you for no reason, without warning. Can you imagine that in real life?7. Invasion of the Body Snatchers
Spock and the Fly try to solve the mystery of a deep space seed that's come to planet Earth to take over humanity. There is a 1956 version as well, but we're particularly fond of this one because it latches on to the late '70s fear of television so well. The spores turn people into mindless drones -- not exactly a killer plant, but it's close enough for us.6. Dr. Who - "Seeds of Doom"
Honestly, this one gets on the list for having one of the best titles around. The best part, though? This is another Antarctica story. Scientists discover a mysterious pod underneath some permafrost and decide -- rather foolishly we might add -- to take it back to their camp for examination. To nobody's surprise, the thing turns out to be an extraterrestrial organism that takes a human as host.5. The Thing from Another World
Unlike its 1982 John Carpenter remake, this one, unfortunately, takes place in the Arctic and not the Antarctic. It's also more about a plant-based alien creature as opposed to the more assimilative monster from the remake. While the monster, er, rather, the thing, looks very human, the scientists soon realize it's actually a plant capable of ingesting mammal blood to regain power.4. The Crawlers/Troll 3/Contamination .7
You know a film is good when it has three different titles. If you're curious about actually watching this one though, you can find it under the nameContamination .7
on Netflix Streaming. Why or how this is related to the Troll movies, we'll never really know, as this one is filled with killer plants, not trolls. In typical '90s fashion, this is as much a film about gruesome death as it as about nuclear waste. When a nuclear power plant dumps some waste into a forest, the roots mutate and start killing and eating people. Makes perfect sense, right?3. As Sete Vampiras (NSFW)
Hopefully you didn't start watching the above video before noticing the NSFW warning, as it's filled to the brim with boobies. While that's certainly part of the reason we enjoyed this ridiculous movie so much, the other part comes from the basic plot: A botanist has a carnivorous plant that turns its victims into vampires, shit goes haywire and a dopey detective and his secretary are forced to attempt to solve the mystery. It's so incredibly stupid it's impossible not to enjoy.2. Attack of the Killer Tomatoes!
Pretty much a classic to camp-film buffs. We don't really have much to add here, as it should be self-explanatory from the movie's title what's happening in the film.1. Little Shop of Horrors

Take your pick between the 1960 or the 1986 version, either way, it's a film/play/musical about a killer plant. We're partial to the 1960 version because it's directed by Roger Cormanand
has Jack Nicholson in it. A young flower shop owner named Seymour accidently creates (or in the case of 1986 version, finds one from outer-space) a carnivorous plant which eventually convinces him to start killing people so the plant will have something to eat.
