A commercial for the Toyota Echo that advertised its spacious interior had a grocery boy help a lady carry her bags to her vehicle. In the back was a massive Venus Flytrap-type plant that snatched up the boy while the woman looked around slyly to see if there were any witnesses. It can still be found on Youtube thanks to vore fans.
Anime & Manga
The pseudo-titular leviathan of Kaiba is a giant planet-eating plant that behaves rather like a sea serpent. Also, it sucks out its victim's memories, leaving them an empty shell.
Ninin Ga Shinobuden had the main character raising a Venus Flytrap to man-eating size, a fact which she was blissfully unaware of. (When she looked at it, birds alighted on it and sang. When she turned around, it ate the birds.)
In the manga Short Cuts, a girl from a distant land wears a flower on her head to eat bad bugs. A man comes up to her and suggests a paid date, and it eats him. By the next day the flower is gigantic, which she explains by saying "There are many bad bugs in Tokyo!"
The Lady of the Knoll (manga)/Rubi Toujou (anime) summons an entire army of these in Rosario + Vampire.
These are referred to by their Japanese trope name, hanabake (lit. "flower monster").
In the second chapter of Season II, Tsukune and pals are faced with a monster durian, which everyone exceptTsukune thought looked delicious. It (predictably) ended up trying to eat them, but they had the last laugh.
Zetsu of Naruto is actually a cross between a two-toned human and a plant that eats people corpses, which he uses to cover the tracks of the Oddly Small Organization he is part of. However, it's worth noting that, while he's drained energy from the living, all the people he actually ate were dead, possibly a reference to plants getting nutrients from decomposing bodies.
The Yuuki family in To Love-Ru has an enormous one planted in the backyard named Celine. Instead of being carnivorous, it's more of a giant pet... that just happens to be a carnivorous plant. For some reason, nobody finds this unusual.
When Celine falls ill (or seems to, at least), the cast leave for space to search for the cure. Too bad the cure is on a planet entirely populated by Man-Eating Plants... and except for the Luckberry Tree, none of them are friendly.
Digimon has the giant plant Blossomon, who is not only a giant flower with a giant mouth, but has vines that each have smaller biting flowers! And razor-sharp leaves that can slice through anything, allowing the flowers to be launched like shuriken. Possibly the most tricked-out Man-Eating Plant around.
James from Pokémon has had the dubious honor of owning two Man-Eating Plants, Victreebel and Carnivine, who constantly gnaw on his head whenever he sends them into battle. Interestingly, this is implied to be how they show affection, and that they aren't trying to eat him (Carnivine even hugged James while gnawing on him. His Cacnea didn't fit the Trope, but it liked to hug him too, and it was a cactus.)
From the sixth One Piece movie, we have (Warning: major spoilers ahead) Lily Carnation. She/it looks like a cute little flower at first, but her/its true form is much more terrifying. Then it absorbs Luffy's crewmembers and outright becomes a Neo Exdeath-likeEldritch Abomination.
Magic The Gathering has a card called Carnivorous Plant. It's a 4/5 creature. Given that the average human is 1/1, in game terms that one big freaking plant. Hell, it could dine on a Giant Spider.
Also, the Phytohydra from Ravnica. It starts out as a 1/1, but hurting it only makes it bigger.
Same thing with the Fungosaur, which is just what it sounds like: A fungus-dinosaur.
On the other hand, squirrels are also usually 1/1 (and can die killing a pride of Savannah Lions), so creatures aren't really to scale. Still, 4/5 is reserved for pretty large creatures.
Yu-Gi-Oh has two ofthese by name and many others. However, most plants in the game are incredibly weak and focus on monster-swarming or swapping. Gigaplant is a straight and powerful example. There's also Traptrix Nepenthes, who's pet or true form is based on the pitcher plant, and Traptrix Tio, who's pet or true form is based on the venus fly trap.
Though black Izs in The Maxx are ambulatory basketball-sized black globs with arms and legs and lots of sharp teeth, they are in fact plants, as they come from Julie's Outback, where every native species, including the predatory ones, are plants.
DC Comics' Poison Ivy plays with this trope. She was once human but is now a mobile, autonomous, sentient and altogether villainous plant. While she may not literally eat human flesh (although this has been alluded to on occasion), she's certainly a man-eater in every other sense of the word. Her sweat contains pheromones which make her just about irresistible to members of both sexes and her lips secrete botanical toxins which she can and will use with relish to dispatch enemies with a kiss. (Enemies meaning anyone she sees hurting a plant, hears about hurting a plant or suspects may have hurt a plant at some point.) She also has the ability to control plants to a degree in which she can control their growth and cause mutations on the fly, most of which are of the literal Man-Eating variety. If she's not in the mood for a decent snogging, she can always feed her current play-toy to her "babies". Arkham Asylum: Living Hell has her admitting to using at least one victim as mulch. Making it deliciously ironic and karmic when one of her "babies" became Harvest, a Plant PersonMind Hive of the people she fed to it that promptly decided to add her to the menu. Thanks to Batman and Robin she survived and the monster vanished, but Poison Ivy was left with a fear of plants for a while.
A villain in Marvel Comics called Plant Man has been known to create these, although he tends to be a joke. (And at one point, he himself says that "the old man-eating plant schtick is corny even for a guy calling himself Plant Man!")
Papa Smurf accidentally created a Smurf-eating plant in The Smurfs story "The Smurfs and the Howlibird" (and its Animated Adaptation), which required a Smurf to chop at its roots to stop.
The Godplant is one of several carnivorous plants which appeared in an episode of Judge Dredd. It ends up eating the lead hippie-like character which is trying to worship it.
The man behind the Addams Family comics also had a group of jungle explorers come across a plant that might be a new species of carnivorous plant. It has one of the explorers halfway eaten.
Films — Animation
The Hungarian animated film Cat City features a gigantic, mouse-eating plant in The Amazon.
Tarzan and Jane are nearly eaten by a mutated plant when entering the meteorite chasm in Tarzan (2013).
Scary Movie 2 featured a Man Smoking Plant: a plant of marijuana grown by Shorty that suddenly becomes a human-sized plant, and rolls Shorty in a joint and smokes him.
One of the jungle perils in The Film of the BookJumanji is a large, rapidly-growing man-eating plant. How big, you ask? At one point it eats a CAR. The car gets bent in half and pulled out of view; any actual devouring is left unseen. But then there's the scene where Peter is nearly dragged into a large carnivorous flower, and if you compare the size of those creepers based on the ones that later crush the car, then the flower at that point...
Adele from Adele Hasn't Had Her Dinner Yet. The Gardener who created her treats her as his pet and affectionately calls her "Adelka" ("Little Adele"). She's seen being fed by lab mice and she has eaten a really big dog. She was created for one purpose only: revenge. She does eat one person near the climax of the movie, though it's nobody of the intended victims, and it's not her creator either.
The Godzilla foe Biollante qualifies. She's several hundred feet high and has a taste for general destruction as well as flesh, which of course irritates a certain radioactive dinosaur.
The animated linking story from Creepshow 2 ends with the main character leading a pack of bullies into an area where he had been secretly planting and growing these for just such a reason, much to the amusement of the creep.
The Ruins. The whole plot revolves in trapping our heroes on the titular ruins that are infested with a man-eating plant that grows into your arteries when it smells blood. Cue plenty of messy, improvised amateur surgery.
Voodoo Island. This low-budget opus offers up Boris Karloff as a scientist leading an expedition to the titular island. Somewhere during the expedition, anthropologist Claire Winters (Jean Engstrom) goes off on her own and decides it’s time for a swim. Never mind that for all she knows the jungle waters might be infested with poisonous snakes, crocodiles, or other predators. Well, she gets far worse than that when she finds herself enwrapped by the tendrils of a prehistoric man-eating plant.
Konga. This 1961 English rip-off of King Kong features a mad professor who invents some kind of serum that enlarges an ordinary chimp, first into a man-size gorilla and finally into a Kong-size monster. Working on the theory that that was not enough to keep an English audience properly horrified, the film also has the professor growing some sort of mutant Venus Flytrap in his hot house. While Konga runs amok at the climax, one of the professor’s female students has the misfortune of getting her arm trapped – a difficult thing to do, since the carnivorous cauliflower has no tendrils to draw her in. The film cuts away, leaving her fate uncertain but implying that she was devoured. Why she could not simply pull her arm free is unclear.
Dr. Terror's House of Horrors. This early anthology from Amicus Productions contains five short stories that run the gamut of classic movie monster cliches: a werewolf, a vampire, voodoo, a crawling hand, and yes – a killer plant. There is little or no explanation for the vicious vine; it is simply noticed growing around an isolated house. Soon, it is snipping phone lines, strangling a hapless victim, and trapping the survivors in the house – until they learn that the wicked weed is afraid of fire, enabling them to escape. The final shot, of the vine batting out the flames left behind by the humans, leaves open the question of whether the plant is truly defeated.
The adaptation of At The Earths Core. In this enjoyably unrealistic depiction of prehistoric life inside the Earth, a man-eating plant makes a brief appearance, interrupting a fight scene between the hero and an adversary. Needless to say, even though the two men had been trying to kill each other only minutes before, the hero saves his opponent from the clutches of the carnivorous creeping vine, and the two become fast friends, joining forces to defeat the evil Mahars that rule the underground world.
Similar shrubbery sprouts up in the 1960 version of The Lost World and in two Hammer Film productions, The Lost Continent and When Dinosaurs Ruled The Earth.
Like everything else in Magnamund, some of the plants Lone Wolf meets try to kill and eat him (not necessarily in that order). The most ridiculous example appears in Book 7, Castle Death. Before you even get to the freakin' castle, Lone Wolf might encounter seaweed that tries to kill and eat him!
The mouse hero in The Cat Trap simply eats his way out of a carnivorous flower.
Though most famous for his detective stories, Sir Arthur Conan Doyle also had his fair share of strange monster stories. His "The American's Tale" (1879) (which has nothing to do with mice, by the way) features a Venus Flytrap big enough to hang a man from. Or otherwise cause bodily harm. Ironically, this is said to occur in Arizona, of all places.
The children's book Pearl's Pirates features a carnivorous plant from which the heroes rescue a lost child. Subverted somewhat in that all the characters are mice, so it's not really a man-eating plant, and far more realistic (some carnivorous plants in the tropics have been known to get big enough to eat small birds and rodents).
Subverted in the Edgar & Ellen books, where aggressive, semi-sentient, meat-eating plants do exist, but most aren't big enough to eat anything larger than a pinky finger. Ellen keeps one as a pet of sorts, as does one of the performers in the Heimertz Circus.
Note that the one belonging to the circus performer is big enough to cram a small child inside, but is stated to be incapable of digesting humans.
In "Beyond the Deepwoods", the first story in Paul Stewart and Chris Riddell's The Edge Chronicles, the protagonist Twig encounters a man-eating tree called a Bloodoak. A parasitic symbiotic plant known as the tarryvine snares victims and then drags them to the Bloodoak where they are devoured, complete with rather graphic descriptions.
In the earliest books carnivorous grass and kelp (or algae) show up as well, and are suggested to be common.
The harpoon tree in The Venom of Argus by Richard Avery (pen name of Edmund Cooper).
The mostly realistic Life of Pi features a rather unrealistic giant flesh-eating plant that appears to be an island. By day it is dormant and the meerkat-like animals that inhabit it go to drink out of small ponds that form at the "center" of the island-plant. By night, the critters have to clamber up into trees, for the island-plant secretes digestive juices that it uses to eat things with. The main character, Pi, discovers the island is carnivorous when he tries to eat a fruit from a tree on the "island," only to find it had a human tooth inside.
Suzanne Collins's Curse of the Warmbloods features the underground jungle of Tantalus, where almost every plant is deadly in some way.
The Coldfire Trilogy has a less animalistic version: trees that drug and paralyze nearby animals, then grow tendrils into them and slowly devour them from the inside out.
The Syren Plant of Kashyyyk in the Star Wars universe can take at least two humans (or a human and a wookie) at a time.
Violet the psycho plant in the first H.I.V.E. book. 'Her' creator, Nigel Darkdoom, had it put on growth retardants after it tried to eat his finger. Then the power is cut to the Herbology lab, and she quickly spreads through the school resulting in a Mass Oh, Crap for all of the characters. 'She' is is only stopped after Otto triggers a cave-in.
Larry Niven's "Orchid Thing" from Gummidgy - a planet where virtually all the native flora and fauna is as likely to try to attack and/or eat you. "Domesticated" ones can be used as decorative houseplants — as long as nobody sticks their fingers too close. Slaver sunflowers are a variation on the theme — when something flies over them, they use their reflective petals to scorch it with concentrated sunlight.
The Iain M. Banks short story "Odd Attachment", while not necessarily about a man-eating plant, is written from the perspective of a lovesick intelligent alien vine who catches a human planetary explorer, that he thinks has fallen from a lucky star, and then plays "she loves me, she loves me not" - usually done by pulling petals from a daisy or other flower - by dreamily and thoughtlessly removing the (male) astronaut's various appendages. Including the "odd attachment". The vine does try to eat part of the astronaut's spacesuit, thinking it's peel, but doesn't like it.
Subverted in Fragment, where the apparent man-eating plants are actually weird animals, they just bear a cursory resemblence to plants.
David Drake often seems to be "phobic" about plants; they won't swallow you whole, but they'll sure suck the nutrients out of you. The vampire honeysuckle in The Jungle is horrifying.
The Tunnels series has the Sweet Traps, plants which knock people out with powerful narcotics and then germinate their spores in their victims' still-living bodies.
The Darksword Trilogy has the blood-sucking Kij vines. The Fool Simkin initially tells his hungry companions that the vines are edible; only after the plant attacks does he correct himself "they consider us to be edible. I knew it was something to do with food."
According to Ponder Stibbons in The Last Continent, the Sledgehammer Plant of Bhangbhangduc has been know to take the occasional human victim who doesn't see the mallet in the long grass.
There's a very nasty one in Deltora Quest which preys on farmers; essentially it looks like a normal plant, until you get too close... and watch the ground open up to reveal jagged teeth and an open maw which essentially drags you in and lets you slide down inside to be eaten... getting torn at the whole time of course.
The carnivorous trees in Septimus Heap, but unlike most man-eating trees, they hunt by grabbing their victims and draining them from their blood.
The Marching Proprut from The Hour Of The Gate is a mobile mass of plants that eats the ground barren as it ambles through the Swordsward grasslands.
One of the Solar Pons stories involved a vine that drained blood.
According to the Star Trek: Vulcan's Soul novels, planet Vulcan has a few of these. Most notable is the S'gagerat, which hide beneath the sand to ensnare prey in their tendrils.
In "The Sagebrush Kid", a short story in Annie Proulx's 2008 Fine Just the Way It Is, a childless Wyoming couple transfer their affections first to a piglet, then a chicken, and finally to a sagebrush they fancy to have the appearance of a child. It is tended and protected, and even fed bones and stray scraps of meat from their dinner-table. Even after the couples' passing, the shrub - now grown to the height of a fair-sized tree - is used to human attention, and meat. It consumes livestock, then soldiers, then a local medico, railroad men, surveyors, and most lately a botanist come to investigate its unusual height and luxuriance.
An alleth sproutling in Galaxy of Fear flicks to sting any hands that touch it, and a computer says that fully grown alleths can eat small rodents. These things are a lot more like Earth's carnivorous plants than is common for this trope. A little later in the same book a much larger plant called the vesuvague is found to be willing and able to strangle people with its vines, but whether that's to eat or otherwise is unknown - one character says he'd have been plant food if someone hadn't saved him, but no "mouth" is evidenced.
Later in the series, on Dagobah there is something called a meat flower, flowers with toothy petals that bite at people. If they've been fed they don't bother unless poked at or disturbed much. The juice from their leaves can soothe the injuries they leave. It's said that there are rare ones out in the swamp, much larger, which can eat people whole rather than just nipping.
A common environmental hazard showing up in a fair variety of forms in Perry Rhodan's various alien natural and artificial jungle settings. How much of an actual threat they present varies, but they're inevitably at least a nuisance.
Tales from the White Hart: In "The Reluctant Orchid", Hercules Keating is nearly killed by a carnivorous orchid. He then attempts to use the orchid to murder his overbearing aunt, but this does not go according to plan.
In The Avengers episode "Man-Eater of Surrey Green", a man-eating plant from outer space lands in Middle England and takes several top horticulturists as its prisoners in an effort to germinate the Earth. Fortunately for the Earth, Steed just happens to be a herbicidal maniac.
Lyekka and her species from Lexx. Their "pods" contain ambulatory predators who occasionally wake up and emerge to feed, using telepathy and shape-shifting to assume a pleasing appearance and lure in their prey. Neither the pod nor the predator can survive long without the other. They can subsist on any animal life, but prefer "fat and greasy" humans by far. Oh, and they vary greatly in size...
One episode of Fringe involved a lonely child, and a sentient, telepathic, hive-minded fungus, which killed people by filling the air with fast-germinating spores (for which the ideal environment to grow was damp, dark and warm... like inside a human body).
Doctor Who. The killer Martian fungus in the Season 6 Episode5 "Seeds of Death", and Krynoid in Season 13 Episode 5, "Seeds of Doom". The latter can turn even nice houseplants into vicious killers.
Stephen Badgeworth in the Pixelface episode "The Problems of Dr Nigari".
In The Addams Family, Morticia owns an "African strangler" named Cleopatra which appears to be a baby man-eating plant. (In one episode, she says it is only three years old, but in another, she claims to have had it before she married Gomez.) In the cartoon version of the series, she own full-grown versions of these monsters.
The Death Bottle in The Future Is Wild approaches this. It's a carnivorous plant that grows in the desert, and conceals a pit over a meter deep and filled with numerous sharp spikes. Animals wander in and impale themselves. It's not quite big enough to swallow an adult human, though.
Max from The Thundermans gives his sister's Venus Fly Trap growth serum that makes it grow huge, super strong and very hungry.
In FarscapeZhan's species turn into this when they start starving. In "Home on the Remains" she starts sprouting buds that release pollen which irritates respiratory systems to the point of incapacitation, acting more and more aggressive and less rational, and requires animal protein to reverse that state, even attacking the others at one point. In the end the crew barbeque the other Monster of the Week for her.
Genesis, in their good old whimsical days, made a delightfully epic song about a war between humans and murderous plants. The plants are winning. It bears the B-movie-esque title Return Of The Giant Hogweed.
Myths & Religion
One of the earliest man-eating plants is the “man-eating tree of Madagascar”, a fearsome entity that was described in 1881 in the South Australian Register, when the newspaper published an account of a "German explorer Carl Liche" who supposedly had eyewitnessed a Human Sacrifice ceremony of the “Mkodo” people in inner Madagascar:
The slender delicate palpi, with the fury of starved serpents, quivered a moment over her head, then as if instinct with demoniac intelligence fastened upon her in sudden coils round and round her neck and arms; then while her awful screams and yet more awful laughter rose wildly to be instantly strangled down again into a gurgling moan, the tendrils one after another, like great green serpents, with brutal energy and infernal rapidity, rose, retracted themselves, and wrapped her about in fold after fold, ever tightening with cruel swiftness and savage tenacity of anacondas fastening upon their prey.
While the “eyewitness account” was suspected to be a hoax early on, the man-eating tree still found its believers; in 1924 former Michigan Governor Chase Osborn repeated the legend in a book Madagascar, Land of the Man-eating Tree. However, it has since been confirmed that neither Carl Liche nor the Mkodo ever existed, and that the story was fabricated from scratch. The hoax seems to have been inspired by the first scientific description of carnivorous plants in Charles Darwin's book Insectivorous Plants in 1875.
Mortasheen has an entire class of plant mosters, but the closest to the classic archetype is the Devilweed. Widoweed is also a notable one, in that literally they only eat men.
There are a number of plantlike monsters in Dungeons & Dragons that are capable of feeding on humans. The most obvious of these is the Mantrap, which is — you guessed it — a flytrap, appropriately scaled up.
Likely the nastiest carnivorous plant in the game was the viper tree, introduced in the Planescape setting. Believed to be the bastard young of Nidhogg, the serpent at the root of Yggdrasil the World Tree, these strange hybrids of demons, reptiles, and plants are trees that are literally made of snakes, found in the Lower Planes. Graz'zt's home realm of Azzagrat has a whole forest of them. (An amusing sidenote to their entry in the rulebook tells of how the Harmonium conducted a poll to find out their food preferences. Among the findings of this rather dangerous project: one in ten interviewed viper trees was able to overpower and devour the interviewer. Other than that, the poll actually seemed to yield some interesting results.)
Taken Up to Eleven with Zuggtmoy, the Demon Queen of Fungus. As her name suggests, she a Demon Lord and is actually more fungus than plant, but according to her official stats in one source, if any mortal is foolish enough to fight her and gets close enough for her to manage a grapple, she can - and will - devour him. (In game terms, as the entry describes it, she "engulfs" the victim, shoving him into her womb, where his Constitution is quickly drained by fungal enzymes until he dissolves completely. Clearly, it's a horrid way to die.
The Dreadstalk from GURPS: Creatures of the Night like to kill adventurers and bury their stuff.
In Myriad Song you can play as one. Morphir start out as ordinary carnivorous plants, but if a female plant is fed the brains of sentient animals they produce buds containing the memories of their victim, often smoked as a hallucinogen. And if they eat a sapient brain they become sapient and gain the ability to shapeshift, often using the absorbed memories to impersonate someone they ate.
The Blood Oak from Deadlands. Originally created for the comic running in The Epitaph magazine, it was later given stats and introduced as an abomination in the game.
In addition to the aforementioned Piranha Plant, Super Mario Fusion Revival has several different Man Eating Plants that populate different worlds. For example, World 2 (based on Earth) has the plants from Metal Slug.
The Pokémon Masukippa/Carnivine is based on the Flytrap. The Oddish line, based on Raffelasia, and the Bellsprout line, based on the pitcher plant, are also based upon meat-eating (but non-mobile) plants. So guess who quickly found himself a Carnivine upon reaching Sinnoh?
For some reason, Pokémon's James never really got over losing his Victreebel (this was one of the two out of nowhere catches in the series, and it's barely even explained unlike Brock's Zubat). There was a few points where a Weepinbell was available during a steal and he wanted to catch it.
The Thorn of Bloodline Champions is implied to do this, as nothing is ever found of their presumed victims that go missing aside from an torn article of clothing.
In an interesting example, the old adventure-game Hugo 2: Whodunit features a field of Venus Flytraps... of an entirely ordinary and realistic size. But you still die if you touch them.
Similarly, the Flaahgra boss from Metroid Prime is a giant Phazon-mutated plant.
There are also large carnivorous flowers in Super Metroid. If Samus falls into one's "mouth," they grab hold of her and deal some damage. Spore Spawn from the same games might also count. It's not known if it's carnivorous, but it does try to kill you.
Also in Majora's Mask, there are several plants in the Woodfall Temple, which float on water like very flat lotus flowers with a tiny, thin row of teeth along the edge and an eye in the middle. Deku Link can use them as platforms to jump across, but if Link climbs on in his regular form, it will close on him, chew him up, and spit him back out. They turn into normal, non-carnivorous flowers when the water is purified.
An expansion pack for The Sims 2 introduces the Cow Plant, which is exactly what it sounds like. However, instead of eating grass, it sometimes lures Sims close with the cake-shaped tip of its tongue and eats them. This causes its udder to fill with milk, which the plant's owner can drink, disturbingly enough. See it in action.
And the "milk" serves as extra potent version of "Elixir of Life" which makes the Sim that drinks it younger. So Sims can live indefinitely if you let the Cow Plant eat a steady stream of random passersby. Also the Sim gets a memory of "Drank (Victim)," some sims really want to drink their enemies' life essence.
'Cake-shaped' is an understatement. Its tongue is shaped like a slice of birthday cake, complete with lit candle.
In The Urbz on GBA and DS there are also man-eating plants in the swamp area and drag you in and eat you (although you can escape via Button Mashing), although being eaten just sends you to the hospital.
The Cowplant has now returned as a premium store item in the Sims 3 Store.
Wario Land Shake Dimension has a few called Venus Guytraps, which eat Wario as well as any enemy that happens to land on one (one mission is actually to feed five enemies to them). There's also Bloomsday/Scumflower, which while it doesn't actually eat Wario as an attack, is pretty much this by how it actually spits out various enemies as attacks.
Tales of Symphonia has a few enemy plants, but 2 are true examples of this trope: The extremely rare Insect Plant and its much more common Palette Swap Upgrade, aptly namedCarnivorous Plant, whose primary attack is to grab one of your characters and eat him/her. (Luckily, this only does a few hits before it spits out said character.) Conversely, the boss version of these, Plantix, doesn't.
Malboros in the Final Fantasy series usually just hit you with their Bad Breath, but aren't above chewing on people once they're out of the player's control.
Civilizations worshiping Gaia or Oranos can summon these to fight for them in Age of Mythology.
There are two puzzles involving these in The Neverhood. In the second, you have to be eaten by it.
In Fallout 2, there are spore plants, which both try to take a bite out of you and shoot you with seeds. More of an early level nuisance than an actual danger. One of these is also sentient, he's named Seymour.
Also in Fallout: New Vegas. The only thing to look out is that they are usually inactive and don't show up on your HUD radar until they wake up (though can still be detected by pressing the VATS button repeatedly while pointing at their direction). Still, they are a minimal threat since their acid spit does low damage, woefully innacurate, and can be easily dodged. They are found in Vault 22, Zion Canyon, and Big MT. There is a boss version called Dionaea Muscipula.
Wizardry has a set of dangerous plants who can move, attack in melee, and shoot thorns. Ah, and some of these attacks are poisonous, and on top of that they can release pollen which causes other Standard Status Ailments.
Spelunky has these, aptly named the Mantrap. They're the only enemy in the game you can't jump on. Unless you're wearing spiked shoes in the original. In the XBLA version, they can't be jumped on at all!
In Secret of Evermore, there are several man eating plants. They drag you in, hit a few times, and spit you out. The first two varieties aren't that dangerous. The third delivers instant kills regardless of level if it's awake. Luckily you can just turn out the lights.
A bird-eating plant features prominently in the Edana segment of Myst III: Exile.
Bionic Commando has a nasty version in one zone, that manages to pop out of the ground, with only a slight rustling to notify you of when you're about to be eaten.
The Holy Sapling in Magical Starsign turns into a flower after your party whacks it; this flower is noteworthy because it can create one of the Millennium Gummies you need to pursue the Big Bad. It has to consume a person to do this, however; cue the Tear Jerker as Semolina offers herself up.
In SimEarth, tweaking the mutation rate allows you to get "carniferns;" if they become sapient their appearance is a Shout-Out to the triffids mentioned earlier.
Poison Ivy commands one of these on steroids (or Titan, rather) to kill Batman in her boss battle in Batman: Arkham Asylum.
And if we turn back the clock to the 90's, the SNES game Adventures of Batman & Robin did the same.
Evil Genius has the Venus Man Trap, which you can research. While it doesn't outright kill agents, it does take a big bite out of their health. There's even a sign next to it saying "Do Not Feed." The agents are obviously illiterate.
Plants vs. Zombies has the Chomper, which will eat almost any zombie whole. Unfortunately, it's vulnerable to attack for around 30 seconds while it chews on the zombie.
In Kameo: Elements of Power One of the Elemental Warriors, Snare, is a giant, acid-spitting Venus Flytrap who can scoop up trolls, spit them out, and, predicatbly, devour them whole.
Castlevania has the Une and Maneater. While they attack you through Collision Damage and projectile-vomited skulls, respectively, the latter is the product of the former once it's consumed enough human blood.
Bug has Venus flytraps (in the ice world, for some reason) and they will eat the character. Subverted, because they're non-lethal and will spit him onto another platform, and also because your character's a bug. Played partially straight in the sequel- staying in a Venus flytrap for too long will get the character killed.
The first boss in Monster Party is a plant enemy that says, "Hello! Baby!" and looks sort of like Audrey II. In the Japanese beta version, it looked much more like Audrey II, and even had a microphone and speaker next to it (which actually remained in the game in a Dummied Out phantom form).
In Spellbound Dizzy there's a man-eating plant. Since Dizzy is an egg, it's harmless. ("Good job it wasn't an egg-eating plant.") Later, you can use some bones to entice the plant to swallow you, transporting you to a different part of the mines.
The "Attending to the needs of a singular plant" storyline in Fallen London. It starts off as an ordinary plant; later, you can feed rats etc. to it; even later, you can start luring people to be eaten by it.
The plant boss from Jak and Daxter will eat the player character if it succeeds in biting him at one point of health.
Kingdom of Loathing has an Audrey II Expy in the Haunted Conservatory and a plant with a meat stack lure in the Spooky Forest. Both will try to eat you.
And Neptune flytraps, several species of algae, and carnivorous dill plants (the last may just be haunted by carnivorous spirits, however). There are over 25 plants as of 2013 which may try to kill you; these are just the ones which are definitely trying to eat you.
The Creeping Chrysanthemums from the Pikmin series. They hide underground and ambush your Pikmin when they get close, and they can take a chunk off of your army in one gulp! However, if you get away fast enough when they lunge, they will end up biting themselves, falling down and giving you a big window of opportunity to kill them.
They serve as dungeon traps in the first act of Albion, though since all you can see of them are their mouths (and in some cases arms with glowing orbs used to attract insects) it's hard to tell if they are actually plants or animals. Turns out they are specialized organs of the dungeon wich itself is a huge living organism. You can feed the large ones with meat so they won't eat you. The small ones with the arms can be temporarily put to sleep with a special fruit, or by putting out the lights.
Joe And Mac has Venus flytrap-like plants that lunge and spit poisonous seeds. The Stage 2 boss is a super-sized King Mook version of these which can grab and eat you, which is an instant kill.
In Brain Dead 13, if Lance clings onto the hilt of the Giant Statue's trident for too long, he'll get flung into the jaws of a yellow, vile plant that can swallow him in a gulp in one death scene.
"There are two risks when colonizing this planet, then, aggressive foliage and tooth decay."
In Astro Marine Corps, there are certain places that have to be jumped over to avoid plants that will come up out of the ground and eat you.
Torchlight II: in the Netherrealms there are leafy pods that open giant maws resembling Audrey II's. Though they're not dangerous to the player, the smaller ones are more than twice human size. The bigger ones can be seen on the distant floor of the Netherrealm, easily large enough to swallow the viewable map.
Starbound has Man-eating Plant People in the Florans, a bloodthirsty, tribal warrior race that treats other sentient races like one would treat plants. And yes, that includes ripping apart and eating without giving much of a crap about it.
Hilarious subversion from The Simpsons: while touring Africa, the family is caught in an enormous man-eating plant. Homer immediately tears his way through it, and when Bart asks him how he did it, he replies: "Psh, it was a flower!"
Another example from "Moe Baby Blues", where the Simpsons, while visitng a botanical garden, come across Venus Flytraps. One lures in Homer with a hot dog and manages to clamp onto his head.
Poison Ivy's greenhouse in her introductory episode of Batman: The Animated Series had a giant Venus Flytrap, complete with tentacles which could grab any passing Batmen and pull them in.
Bushroot from Darkwing Duck is a quasi-example, as he's a duck turned into a plant. However, his powers let him turn any plant into a deadly warrior, particularly his giant venus fly trap, named Spike.
In an Aladdin: The Series episode, Genie encounters a huge carnivorous plant in Mozenrath's lair.
In an episode of the Super Friends, a meteor falls into a swamp, turning the naturally harmless water lilies into lumbering plant monsters that can turn people and animals into plant-covered zombies whenever they are touched or shoot their seeds at anyone.
In one episode of Teen Titans, Starfire, who is depressed because she is undergoing transformation (which is sort of like puberty to her species) is attacked by a carnivorous plant on an alien planet; but it spits her out. This makes her even more depressed, as she thinks the plant finds her revolting. Later, after a far-more wicked monster threatens to devour her, the other Titans come to her rescue, and the plant appears again, this time preying on the monster.
He-Man and the Masters of the Universe (2002) had a villain named Evilseed, a sentient plant being who despised humanity for 'gorging [them]selves on plantlife' and sought to destroy them. The minions he could create were some kind of plant/dinosaur hybrid, and later a hydra-esque creature. Fortunately he gets a beatdown from his ancient foe, Moss Man; a more benevolent plant guy.
In one episode of Inspector Gadget, Doctor Claw's scheme involves using a growth serum on plants. His henchman uses it on a Venus flytrap to sic it on Gadget. (As usual, Penny and Brain have to rescue him, subduing the creature with knockout gas.)
The second season of the animated cartoon Attack of the Killer Tomatoes! has the titular villainous veggies and the tomato centurions now being capable of chowing down on humans.
Little Shop, the animated adaptation of Little Shop of Horrors.
Weirdly and Creepella Gruesome, a family that appeared on the fifth season of The Flintstones (inspired by The Addams Family) had one of these, along with other monsterous pets. It tried to eat Fred more than once, but fortunately, its masters were quick to tell it to heel.
Chris has one in Total Drama, and he uses it as an obstacle in a couple of challenges
The Season 4 premiere of My Little Pony: Friendship Is Magic has Ponyville being invaded by pony-eating Plunder Vines, thanks to the seeds planted by Discord towards the end of his first reign, which were kept in check by the Tree of Harmony's reserve magic until now.

In Rocket Robin Hood, Rocket Robin Hood is attacked by several species of man-eating plants, including giant Venus flytraps, when he lands on "The Living Planet", but manages to elude them all only to find himself caught in a deadlier trap (from which he is rescued in the nick of time).
In the Codename: Kids Next Door episode "Operation: A.F.L.O.A.T.", the team gets lost in a sea of asparagus while escaping from Stickbeard's ship. (It's a weird cartoon.) Things only get worse when their craft is attacked by a "great white asparagus" that starts hunting them down, and they're saved only when Stickybeard shows up and guns it down. (The candy pirate later tells them, "I may be out to destroy you Kids Next Door, but I'll be dipped in chocolate before I let a blasted vegetable do anyone in!")
While there's no documented cases of a human falling victim to it, there is a plant that feeds on things as large as sheep, after a fashion. Though it's a far cry from the typical Venus Flytrap on steroids image associated with this trope, the Puya chilensis is known to trap animals that blunder into patches of it with its thick, barbed leaves where they starve and decompose, granting extra nutrients to its soil. This is hardly their main form of nourishment, though.
