The hero and his [[PluckyComicRelief comic-relief]] {{sidekick}} are trudging across the burning sands, looking for water or shelter, and they walk past a towering saguaro cactus. The problem is, they're marching through the deserts of Arabia...

In fiction, most deserts have cacti, usually the classic two-armed [[http://en.wikipedia.org/wiki/Saguaro saguaro]], though barrel and beavertail cacti are also popular. But the Sahara only has bushes, dunes and bare rock - cacti are only native to the Americas. And despite its common depiction as the ubiquitous cactus, the saguaro only grows in the Sonoran desert, which covers mostly parts of Southern Arizona, Northern Mexico, and a tiny bit of southern California. It does ''not'' include any part of Texas, Utah, New Mexico, Nevada, or even Northern Arizona.

The ''entire family'' of Cactaceae is exclusive to the Americas in its native range -- yes, even in high-altitude and colder areas.[[note]]The [[http://en.wikipedia.org/wiki/Rhipsalis_baccifera mistletoe cactus]] is the one exception: it can be found in Africa and Sri Lanka.[[/note]] You'll only see them elsewhere if they're invasive or purposely cultivated for their fruit or decoration. Of course, the range of cactus species available in [[FantasyWorldMap fantasy worlds]] is up for grabs, but seeing them in the wild outside the western hemisphere is right out.

If you want to establish that you're in a hot desert, there's no better way than to throw in a cactus. Increasingly, this trope is used to justify a IntoxicationEnsues or a MushroomSamba; while many have heard of [[http://en.wikipedia.org/wiki/Peyote Peyote]], few realize that it is a cactus - at least until someone on television is trapped in the desert, dying of thirst, and remembers that cacti are full of water... AndKnowingIsHalfTheBattle.

An alternative stereotype is that all deserts are nothing but hot, sandy wastelands--aside from the cacti--completely disregarding the fact that all deserts except Antarctica have vibrant ecosystems with their own unique animal and plant life. While cacti are the most well-known, you also have [[http://en.wikipedia.org/wiki/Aloe Aloes]], for example, which are native to Southern Africa and parts of Arabia and [[http://en.wikipedia.org/wiki/Agave Agaves]] which were native to Mexico but may now be found across the world. The bit about sand is also exaggerated, as many deserts, including where cacti grow native, are rocky rather than sandy. Additionally, a desert isn't always hot — it's less about heat and more about extremes. Desert landscapes have a tendency to fluctuate in temperature, meaning that someone traveling through the desert could potentially have to worry about heatstroke and hypothermia within the same 24-hour period.

Probably a result of either ArtisticLicenseGeography or CaliforniaDoubling due to lacking the budget to film on location elsewhere.

A subtrope of MisplacedVegetation.

!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]
* A brief gag during the Arabasta arc of ''Manga/OnePiece'' had Luffy drink from a cactus, despite the kingdom being more Arabic than American, with [[IntoxicationEnsues near-identical results]] to the ''WesternAnimation/AvatarTheLastAirbender'' example below. Luckily, Chopper, the team doctor, happened to have a needle full of tranquilizer on him...
* In the MushroomSamba episode of ''Anime/CowboyBebop'', the crew runs out of fuel and crash-lands on Europa, the moon of Jupiter. The series often pays homage [[SpaceWestern to its roots]], and this part of Europa just so happens to have been terraformed into a desert typical of the American southwest, complete with cacti.
* Averted in ''Manga/DesertPunk'': the series is set in an AfterTheEnd Kanto region of Japan which has been turned into a desert, and thus has no cacti.
* ''IriyaNoSoraUFONoNatsu'' uses the "all deserts are sandy wastelands" variation to portray Nevada, complete with a raging sandstorm.
* In ''Anime/DigimonAdventure'', Mimi's crest is found inside the flower topping a gigantic cactus in the middle of a desert. How gigantic is this cactus? It's as tall as a cruise liner is long. In this case, it's {{justified}} due to being in [[{{Cyberspace}} the digital world]].
[[/folder]]

[[folder: Comic Books ]]
* In ''ElfQuest'', [[http://www.elfquest.com/gallery/OnlineComics/OQ/OQ02/DisplayOQ02.html?page=10 cacti provide the Wolfriders with an emergency water supply]] during their desperate desert journey. Possibly justified because it takes place on an Earthlike planet with almost-identical flora and fauna.
** Realistically, they pass through both sandy dunes and rocky flats during their journey, and the cacti only grow in the latter.
* Averted in ''[[Franchise/{{Tintin}} The Adventures of Tintin]]'', which places the characters in Arabian Deserts numerous times with no cacti.
* In one comic, ComicBook/{{Bamse}} dug next to a cactus, hoping to find water. He instead found oil, which was spotted by ''bedouins'', who then came to Bamse's aid.
[[/folder]]

[[folder:Films -- Animated]]
* ''WesternAnimation/{{Rango}}'', which the film states takes place in the Mojave Desert, has plenty of cacti in the desert around the town of Dirt. While there are in fact plenty of species of cacti that grow natively, the lovingly and accurately rendered saguaro does not.
* Averted in ''Disney/{{Aladdin}}''. There are no cacti in the Arabian Agrabah desert.
* Both ''WesternAnimation/{{Madagascar}}'' and ''Disney/TheJungleBook'' featured cacti growing in ''jungles''.
** On the other hand, the only cactus native to the Old World, the epiphytic Mistletoe Cactus, is found in rainforests of Africa and Madagascar, having been introduced there via migratory birds.
[[/folder]]

[[folder:Films -- Live-Action]]
* This is {{averted|Trope}} in Creator/BobHope and Music/BingCrosby's definitive ''Road To...'' movie, ''[[Film/RoadTo Road to Morocco]]'' (which is peculiar, considering that classic films in foreign locales tend to go for the obvious stereotype). There are plenty of palm trees and rose bushes, but not a single cactus in the roughly hour-and-twenty-minute film.
* In the silent film ''King Of Kings'', directed by Creator/CecilBDeMille, Jesus Christ (played by actor H. B. Warner) preaches in the Holy Land while standing next to a beavertail cactus.
** In the 1961 film that shares that title, Jesus Christ (played by actor Jeffrey Hunter), while fasting in the wilderness, breaks open a beavertail cactus leaf and drinks the water inside.
* The film version of ''Film/FearAndLoathingInLasVegas'' pays tribute to Ralph Steadman's original art -- which depicted saguaro cacti on the road between Barstow and Las Vegas -- by inserting the occasional black cardboard cutout of a saguaro in the background of some of the driving scenes.
* Averted and lampshaded in the 2007 movie ''Film/WildHogs''.
* The scene in ''Film/BillAndTedsExcellentAdventure'' where they visit 19th-century New Mexico prominently features a saguaro in its opening shot. The movie ''was'' filmed in the Sonoran Desert, so perhaps this is mostly as example of Arizona Doubling, but even still, they ''could'' have built the set away from the saguaro... couldn't they?
* Justified in the film version of ''Theatre/JosephAndTheAmazingTechnicolorDreamcoat''. Although there are saguaro cacti in the "One More Angel" scene, which is set in Canaan, the song itself has a country-western tone, so the cacti make sense.
[[/folder]]

[[folder: Literature ]]
* In Robert E Howard's Red Nails, Conan the Cimmerian and Valeria travel across a "cactus-dotted plain" and spend the night in a ring of cacti for protection while adventuring in prehistoric Africa.
* Justified in Frank Herbert's ''Franchise/{{Dune}}'', cacti are introduced to the [[SingleBiomePlanet desert planet]] Arrakis as part of a terraforming effort. Though the planet is so arid that initially they can only survive in carefully guarded parts of the mountains (away from the [[SandWorm worms]]) with dew collectors providing them with water.
[[/folder]]

[[folder: Live Action TV ]]
* Intentionally used in ''Series/MontyPythonsFlyingCircus'' in "Scott of the Sahara" with cardboard saguaro cacti in the Sahara Desert as produced by a bad moviemaker.
[[/folder]]

[[folder: Newspaper Comics ]]
* In ''{{Peanuts}}'', Snoopy's brother Spike is always portrayed sitting under a two-armed saguaro cactus. He actually has a house inside a hollowed-out cactus. Although he lives in Needles, CA, that's too far north for saguaros.
* ''Crock'' features cacti prominently in the Sahara.
[[/folder]]

[[folder:Professional Wrestling]]
* One of Big Japan Pro Wrestling's signature GimmickMatches, The Scorpion Death Match, replaces the barbed wire used in the ''Piranha'' Death Match with cacti, for a more desert feel. This ignoring that deserts in Japan don't have cacti.[[/folder]]

[[folder: Video Games]]
* A lot of ShiftingSandLand levels in games have cacti, which sometimes act as enemies or spiky obstacles to damage your health. [[BuildLikeAnEgyptian Pyramids]], too.
* Gobi's Valley in ''VideoGame/{{Banjo-Kazooie}}'' includes these, despite being ancient Egyptian themed and named after (a camel named after) a desert in Asia.
* In ''VideoGame/{{Terranigma}}'', the Gobi desert (which is located in Asia, by the way) is covered in cacti.
* Set in the Mojave, [VideoGame/FalloutNewVegas]] features Agaves, barrel cacti and prickly pears that will constitute 95% of the Courier's diet. No Saguaros, happily.
* Route 111 in ''[[VideoGame/PokemonRubyAndSapphire Pokémon Ruby/Sapphire/Emerald]]'' includes a desert and is the only place you can find a Cacnea, despite Hoenn being a FantasyCounterpartCulture to the Japanese island of Kyushu.
** Likewise Route 228 in Diamond/Pearl/Platinum, featuring Cacnea's evolved form Cacturne. This despite Sinnoh being based of Hokkaido.
*** Then again, having designed the Pokémon before the routes, where ''else'' could they have placed them, which would be at least [[FridgeLogic somewhat logical]] to the player?
** The Desert Resort in ''VideoGame/PokemonBlackAndWhite'' features a new cactus Pokémon, Maractus, though Unova is at least based on someplace in the New World (New Jersey and New York).
* ''[[VideoGame/MarioAndLuigiSuperstarSaga Mario & Luigi: Superstar Saga]]'' features the Spiky Snifits who look like saguaro cacti. You find them in the desert Teehee Valley. Other [[Franchise/SuperMarioBros Mario games]] have the cactus enemy Pokey, who appears in just about every desert level. (Except World 2 of ''VideoGame/SuperMarioBros3''; Pokey wasn't in that game.)
** And the interesting thing? The whole cacti "project" started with the desert levels of ''VideoGame/SuperMarioBros2'', which is practically a Marionized version of ''VideoGame/DokiDokiPanic'', a game with an ''Arabian'' theme.
* In the original ''VideoGame/SpyroTheDragon'', there were cacti all over the desert levels. Some of them would even shake themselves to get the soot off if you used your flame attack on them.
** Rather impressively, though, the cacti only show up in levels with an "American" theme within the trilogy. Dry Canyon and Cliff Town are both based on areas ("Colorado" and "Mexico") which might be expected to have cacti, and Dino Mines is the Old West with dinosaurs (and cacti). Skeletos Badlands has cacti as well, but no clear effective location. The two desert levels which DO have a clear non-American location (Scorch and Desert Ruins) are cacti-free.
* ''VideoGame/ZeldaIITheAdventureOfLink''. Love it or hate it, there are cacti in enemy battles in the desert. These are only one-armed, though.
** The Gerudo Desert in ''Ocarina of Time'' and ''Twilight Princess'' is notable for being cactus-free.
*** There are Leevers in both,which are basically mobile, carnivorous cacti. They appear less cactus-like in some games, but the ones in ''Twilight Princess'' (also seen later in the spinoff ''Link's Crossbow Training'') are unmistakably evil prickly pears. Leevers are also found in the desert section of the original game, which is otherwise devoid of cacti.
*** Note, though, that ''Zelda'', along with many fantasy games, gets a pass on the geographically-incorrect part since [[HandWave it's not set in the real world]] and therefore can have any type of biome it wants as a backdrop.
* Another notable aversion: the desert region of ''GuildWars'' are mostly, if not entirely, cactus-free. Appropriate, as the desert regions are all in Elona, the local analogue of north Africa.
** Though at the same time, there aren't really any Succulents, which ''are'' native to Africa and Arabia. (Such as the famous Aloe Vera)
* ''VideoGame/Kirby64TheCrystalShards'' contains a SingleBiomePlanet based off of deserts. The first level of this planet is based off of ancient Egypt, yet the background is filled with cacti.
* ''VideoGame/TalesOfVesperia'' has examples this, it features a desert where you must deflate cacti with your sorcerer's ring to restock your water supply periodically. Also cactus monsters live in it.
* ''VideoGame/GoldenSun'', despite being set in a fantasy world, is guilty of two deserts with cacti in the battle scenery in the first game. The America-equivalent continents don't get explored until the second game, and the deserts on those use battle scenery that ''doesn't have cacti''. Whoops.
** This is actually more of an aversion, as it disregards the trope quite nicely.
* In ''TeamBuddies'', you are sure to find cacti (and possibly pyramids) in all the desert levels.
* The opening stage of ''VideoGame/MegaManZero 2'', a desert, had tall ''mechanical'' saguaro cacti that fired spikes and round barrel cacti that rolled about and shot bombs.
** In ''Zero 3'', Glacier le Cactank is an aversion. If you haven't guessed it yet by his name, he's AnIcePerson. His territory is a ''snowy'' region.
* ''FarCry 2'' falls prey to this Trope, having big Saguaros...in the middle of Africa...
* In ''VideoGame/DwarfFortress'', the default data files specify that all desert biomes contain saguaros. Fortunately, the game does recognize 3 different types of deserts (sand deserts, badlands, and rocky wastelands), so the game's data files can be modified to make the situation slightly more realistic.
* ''RollerCoasterTycoon'' had Saguaro cacti available in the scenery window no matter where you go, allowing you to place them in the Arctic if you so choose. But more to the point, an Egypt-themed premade scenario also had some sitting around. Possibly justified in that it's quite literally TheThemeParkVersion, and a cactus will grow just as well in a fake Egypt as a fake Wild West. Nobody really ever said they were real, live cacti either.
* Averted in ''VideoGame/{{Halo 3}}'', an entire mission (one of the game's longest in fact) is set in a desert and features not one cactus.
* No matter where you deploy for UFO recovery in the world in ''VideoGame/{{X-Com}}'', as long as you touch down in desert, you ''will'' see cacti and pyramids when you disembark from the Skyranger.
* ''[[VideoGame/BackyardSports Backyard Football]]'' has Cactus Gulch, which has...well...you know.
* ''VideoGame/Jak3Wastelander'' has cacti spread throughout the Wasteland.
* The first ''VideoGame/ToejamAndEarl'' game had [[QuicksandSucks sand]], mostly in later levels. The sand nearly always came with cacti.
* Played realistically in ''VideoGame/WorldOfWarcraft'', where Durotar is the only desert region in the game with cacti. Silithus and Tanaris are just sand dunes, while the Barrens and Desolace (before the Cataclysm) are more like savannahs.
** Tanaris does have Thistleshrub Valley in one corner of the zone, which is a large cacti jungle, but that's TruthInTelevision, as the RealLife section can attest to. Also, Uldum, which is an Egypt analog, doesn't have a single cactus in it's entirity, averting this trope yet again.
* Averted in the ''VideoGame/ZooTycoon'' games, in which placing cacti in an exhibit with North African, Asian, or Australian desert animals reduces the exhibit's rating for species-appropriateness.
* ''VideoGame/{{Bug}}!'' has is a desert level, and there ''are'' saguaro cacti. However, the level ''is'' based off the Arizona Desert, so it fits.
* In ''VideoGame/RuneScape'', cacti abound in the very Arabian/Egyptian-themed desert. Cutting them and drinking their water is kinda useful for not dying from the heat, so they could be given a pass.
* Cacti in ''VideoGame/{{Minecraft}}'' can rarely spawn anywhere on sand, except for desert biomes where they are everywhere.
* ''VideoGame/PuttPutt Travels Through Time'' has cacti in the Old West time period.
* ''FreddiFish 4: The Case of the Hogfish Rustlers of Briny Gulch'' takes place in the Old West, so of course it has loads of cacti.
* In ''VideoGame/{{Terraria}}'', all desert biomes (created when there's a large enough concentration of sand) automatically grow cacti.
* Possibly averted in all of the ''VideoGame/{{Mount and Blade}}'' games. No cacti are seen throughout the desert areas. However, the isometric travel map has very little detail, so there may actually be cacti there, just not visible or in any of the combat environments.
* ''VideoGame/Uncharted3DrakesDeception'' averts this, with the desert in question being in the Middle East. Sadly for Drake, there isn't any other life either.
* In ''VideoGame/SuperTuxKart'', some deserts have cacti. Coyote Canyon is an add-on racetrack in a rocky desert with saguaro cacti. Coyote Canyon resembles the Grand Canyon in Arizona, though saguaro is not among the cacti at the Grand Canyon. Shifting Sands has no cacti, because it resembles [[BuildLikeAnEgyptian Egypt with pyramids]].
* VideoGame/{{Borderlands 2}} has an unusual variation: Stinging Cacti, which are a bit like if a geneticist spliced Electric Eel genes into a cactus plant. The catch is they only appear in the ''Arctic'' sections of the game... [[TruthInTelevision which]] ''[[TruthInTelevision are]]'' [[TruthInTelevision deserts]].
** The regular variety of cacti (called 'Stactus plants' in-game) appear in the regular sand-and-heat deserts of Pandora.
* Cacti are the go-to decoration for any and all deserts in ''VideoGame/{{Clonk}}''.
* ''VideoGame/HalfLife'' has a few saguaro cacti in the outdoor areas... despite being located in New Mexico. (While New Mexico has cacti, it doesn't have saguaros.)
* Most maps in ''VideoGame/CarnivoresTriassic'' contain one variation or another of prickly pear and occasionally saguaro, sometimes in surreal color schemes, though they're not very common. [[HandWaved Justified]] in the game taking place on an alien planet, not on prehistoric Earth.
* In ''VideoGame/TheTwistedTalesOfSpikeMcFang'', Kalala Desert, as well as the preceding area, Rat Mountain, doesn't just have saguaro cactuses--it has maraca-wielding Dancing Cactuses!
* ''{{VideoGame/Starbound}}'' has cacti in the desert, but this is perhaps justified because the game takes place [[{{RecycledInSpace}} IN SPACE]]!
* Played straight in ''VideoGame/{{Westerado}}'', like in the Westerns it was InspiredBy.
* Played straight in the desert levels of ''VideoGame/{{Nihilumbra}}''.
* VideoGame/{{Infinite Undiscovery}} features a pair of Barrel Cactus creatures with the distinctly Mexican names "Amigo" and "Tequilo". Man-sized walking Barrel Cactus. That can shoot needles in multiple directions simultaneously, spew spores when struck by attacks that might paralyze/poison you, and bowl you over with a rolling attack. The former is played straighter by being found in the desert region of the game, while the latter is peculiar by being found in a tropical jungle setting. Which works in its favor, since its coloring gives it a bit of camouflage against the planty surroundings.
[[/folder]]

[[folder:Webcomics]]
* Wally, of ''WallyAndOsborne'', [[http://wallyandosborne.com/2005/12/02/cowboys-sunset has made snow ones in Antarctica while imitating a cowboy.]]
* ''Webcomic/TheOrderOfTheStick'' has a big, sandy, Sahara-like desert on the Western Continent with camels, giant sandworms and [[http://www.giantitp.com/comics/oots0692.html at one instance]], a cactus.
[[/folder]]

[[folder: Western Animation ]]
* In ''WesternAnimation/AvatarTheLastAirbender'', a show set in a mythological Asian-esque land, Sokka sings "Drink cactus juice, it'll quench ya. Nothing's quenchier" while [[IntoxicationEnsues high on cactus juice]]. However, the cactus Sokka just drank from turns out to be the only one they ever see along the way.
** [[MemeticMutation It's the quenchiest!]]
* [[WesternAnimation/LooneyTunes Road Runner and Coyote]] cartoons, obviously. Justified in that they take place in the American Southwest, where cacti are indigenous.
* In ''WesternAnimation/AmericanDad'', the episode Delorean Story shows Stan driving his son on the way to Albuquerque, with nothing but sand and saguaro cacti surrounding the road. In reality, they would have seen a few forests along the way considering at least 5 climate zones exist around Albuquerque.
* Also averted in ''Anime/TheMysteriousCitiesOfGold'', and they actually point out that cacti are full of water when the characters are stranded on the Galapagos islands.
* Justified in ''TheMagicSchoolBus'', because they actually go to an American desert.
* ''WesternAnimation/JimmyTwoShoes'': The only time in the series a desert is scene, it involves a lot of cacti.
* Averted in ''WesternAnimation/CodeLyoko'' as there are no cacti in the Desert Sector.
* An episode of ''WesternAnimation/KimPossible'' that takes place in the Mojave Desert inevitably includes saguaros as part of its landscape. In one case, the keycard lock for accessing an ElaborateUndergroundBase was hidden in a fake cactus.
[[/folder]]

[[folder: Real Life ]]
* In deserts and other arid regions of southern Africa there is a family of succulent spiny plants called Euphorbia; that look suspiciously similar to Cacti but are ''not'' related to cacti ''at all''. The two families independently evolved multiple similar forms to adapt to similar niches (barrel-shaped forms, saguaro-shaped forms, ocotillo-shaped forms, etc.)
* Played dead-straight by the transplantation of cactus species across the planet. The prickly-pear cactus, also known as the ''tzabar'' or sabra, has become known as emblematic of Israelis. It's native to southwestern North America, but don't go telling that to the hummus company.
** It's also a beloved plant for the Berbers in Morocco, who have a lengthy tale about how Allah gave it to them thousands of years ago so they could survive being lost in the desert by eating its fruit. [[SeriousBusiness Never mention]] in their presence that it was introduced by the Spanish just a few centuries ago.
* After the 2004 tsunami, prickly pear cacti were found growing in southern India.
* Cacti may often be found growing in Southeast Asia. The Pitaya fruit, also known as Dragonfruit, is native to Mexico but was popular in Vietnam and Thailand.
* Incidentally, the deserts of America, Australia, and Africa all have their own unique range of desert flora found nowhere else on the planet. So you can even tell if they're doubling Australia for the Sahara if you know your plants.
** Unless they are invading plants. Nopales and agaves (both American in origin) have successfully colonized parts of Australia and the Mediterranean.
** Or transplants. Aloe plantations can be found in Australia.
* The opposite of this is also true. Cacti don't immediately imply desert. Prickly pears grow throughout a lot of the Midwest, up into Canada. There are lots of epiphytic jungle cacti. And then you have the Pereskias, better known as the rose or leaf cacti, which are non-succulent cacti with broad leaves. They are still exclusively native to the Americas (unless transplanted elsewhere), however.
** Prickly pears are also found across North Carolina, which at any point in the state is definitely not a desert (it's quite humid and gets plenty of precipitation). They're found in the grassy, undeveloped areas of the Outer Banks, into which locals will warn you not to wear sandals.
** Some cactus species grow tall and lush enough to form ''forests'', all on their own. Check out pictures of the smaller Galapagos Islands if you doubt this.
** Before the introduction of the Cactoblastis cactorum, the prickly pear was a SERIOUS feral plant in Australia.
* It's quite possible to grow cacti in your own lawn or garden. [[CaptainObvious They're low maintenance]], and can deter intruders (and [[HilarityEnsues injure the unwary]]). Just watch where you walk barefoot.
* It is also noted that there are indigenous cacti for places like New England that look like [[http://en.wikipedia.org/wiki/Opuntia_humifusa paddle cacti.]]
* Cacti have been found growing in the Indiana Dunes State Park by Lake Michigan.
* Averted, of course, by Antarctica, the world's largest desert, which lacks cacti.
* Perhaps the most widespread habitat for modern cacti is ''indoors'', as they're quite popular all over the world as easy-to-care-for houseplants.
* The [[AprilFoolsDay "Pirates' Treasures"]] version of Google Maps use cactus to indicate deserts-- even Arabian Desert and Gobi Desert.
* [[http://en.wikipedia.org/wiki/Rhipsalis_baccifera Rhipsalis baccifera]] is a cactus that grows in Africa and Sri Lanka. How it managed to get there while all other cacti are found in the Americas is unknown.
