This list of fictional plants describes invented plants that appear in works of fiction.
In fiction
In J. R. R. Tolkien's Middle-earth
Aeglos: A plant similar to a gorse, named for the Elvish 'snow-thorn' Athelas: A healing plant with long leaves (also known as Kingsfoil or asëa aranion). Elanor: A small star-shaped yellow flower from Tol Eressëa and Lothlórien. Mallorn: A huge tree with green-and-silver leaves turning golden in autumn and remaining so till spring, upon which the Elves of Lothlórien housed. Nimloth: The White Tree of Númenor, a seedling of Celeborn, a seedling of Galathilion, created in the image of Telperion. Niphredil: A small white flower from Doriath and Lothlórien. Pipe-weed: "A strain of the herb nicotiana" (tobacco); varieties mentioned include Longbottom Leaf, Old Toby, Southern Star (grown in the Shire) and Southlinch, from Bree. Oiolairë: An evergreen fragrant tree highly esteemed by the Númenóreans. Simbelmynë: A white flower that grew in Gondolin and Rohan (also known as Evermind and Alfirin). Two Trees of Valinor: Magic trees that illuminated the Blessed Realm in ancient times.
In J. K. Rowling's Harry Potter series
Gurdyroot: A plant that resembles a green onion. It is the basis for a foul-tasting purple infusion brewed by the Lovegoods to fend off Gulping Plimpies. Considered not very original by gardening expert Charles Elliott, depending on a funny name for effect. Mandrake: Tubers that look like babies when young. Their screams can kill when fully grown. A potion made from mature mandrakes can reverse petrification. The Whomping Willow: A tree with animate, club-like branches hiding a secret passageway.
In Brandon Sanderson's Cosmere Series On the planet Roshar (The Stormlight Archive) Firemoss: A red-brown moss that, when activated by rubbing between the thumb and forefinger, releases wisps of smoke that create feelings of euphoria when inhaled and is used as a recreational drug. Firemoss is highly addictive, limiting its medicinal use, though it is sometimes used to reduce cranial swelling and offer pain relief. Knobweed: Like most of the plants found on Roshar, knobweed has adapted to survive the planet's harsh storms. The reed-like stalk anchors itself directly to stone and the frond found at the top of the stalk has the ability to contract and retreat into the stalk during storms for protection. Knobweed reproduces by releasing fluffy pappuses that carry seeds into the air. The milky white sap found inside knobweed stems is a natural and highly valuable antiseptic used in the field and by established apothecaries. Prickletac: Prickletac plants are the colonies of much smaller living buds. As each generation of buds dies it converts to a hard, stony material which the next generation builds upon. Prickletac's reproductive system is based on this oddity – when a 'limb' grows too large it breaks off and falls to the ground, scattering living buds. Also known as Twisted Spine. Rockbuds: Rockbud is both a general term for several shelled plants on Roshar, including Lavis Polyps, Vinebuds, and Prickletac Shrubs, and the proper name for a specific plant. The true Rockbud plant is a shelled plant containing lengthy tendrils that reach out to lap up water (and occasionally animal blood). The size of fully grown rockbuds depends largely on climate. In colder climates they grow no larger than a human fist, while rockbuds in warm climates can grow to the size of a barrel. Rockbuds are harvested for consumption, limited medicinal uses, and paper making. Shalebark: A class of stony, fanlike plants often used for decoration and landscaping. On the planet Nalthis (Warbreaker) Tears of Edgli: Vibrantly colored flowers that grow only in the temperate T'Telir climate. Highly valuable both economically and magically. On the planet First of the Sun (Sixth of the Dusk); Unnamed Telepathic Trees: Many flora and fauna on this planet communicate with a form of natural telepathy. Certain unnamed plants living on the islands that make up the Pantheon send false thoughts of wounded or frightened animals to attract predators, which often fight and leave victims dead near enough to the tree to provide nutrition. These plants are not directly carnivorous. On the planet Taldain (White Sand series) Dorim vines: Dorim vines live under the sand that covers most of Taldain's Dayside continent, reaching down to the water table where they fill themselves with water as a defensive mechanism against predators – the hard shells of many of the continents animals is dissolved by contact with water. Pouring water onto sand draws nearby vines out of the ground.
In Rebecca Yarros's Empyrean Series
In Fourth Wing Sources:
Fonilee Berries: The berries are purple in color but a light lavender color when unripe. They are found on a single vine near Iakabos River. Violet uses these berries against her first sparring opponent, Oren Seifert by sprinkling a dried powder of unripe berries on his scrambled eggs for breakfast. This causes him to experience nausea and limiting his ability to fight. Leighorrel mushrooms: Prior to her second fight, Violet put these mushrooms into the lunch of her opponent. This causes her opponent to experience hallucinations, making it difficult to concentrate on the fight, allowing Violet to win Zihna (root): Violet uses the root of this plant on her third opponent, causing him to experience numbness and making him unable to fight. These roots are found near the ravine. Tarsilla leaves: For Violet's fourth match, she puts Tarsilla leaves in her opponents tea prior to fighting. These leaves cause her opponent to experience blurry vision, making it difficult to fight. Carmine tree (bark): Violet puts the bark of the carmine tree in her opponents canteen to win her fifth sparring match. The bark causes extreme sickness similar to food poisoning, with nausea and sluggishness. Due to being in the canteen, the entire squad becomes ill, not just her opponent. Walwyn fruit peels: Prior to what would be her sixth match, Violet puts the fruit peels into the icing of her opponent breakfast, Rayma Corrie. These peels diminish coordination and balance when eaten. However, due to a mistiming, her opponent ends up going to the Healers and this fight does not occur.
