Plants of Harry Potter: a Potterhead's guide to the houseplants of Hogwarts

By Planthead Team · Jun 7, 2026

Every Planthead has, at some point, looked at a leafy little weirdo on their shelf and thought: this thing has personality. J.K. Rowling clearly agreed. Hogwarts has an entire subject — Herbology — dedicated to plants that scream, bite, glow, and occasionally save your life. 🌿✨

Pour a cup of tea. We're touring greenhouse three.

🌱 Mandrake — the screaming root

The plant: a tufty green seedling on top, a furious humanoid baby underneath. Pull one up bare-eared and you faint (or worse).

Real-world cousin: Mandragora officinalis is an actual plant — short, leafy, with a forked root that medieval herbalists genuinely believed shrieked when uprooted. They tied dogs to it. We are not joking.

Grow this instead: a Mandrake-energy houseplant is anything bushy and dramatic from a tiny pot — try a Tradescantia zebrina or a curly Boston fern. Loud hair, quiet life.

🪢 Devil's Snare — the cuddler with bad intentions

Likes: damp, dark, and wrapping itself around your throat. Weakness: sunlight and warmth, which is excellent news for the rest of us.

Real-world cousin: in our world, "Devil's snare" is sometimes used for Datura stramonium (don't), but the vibe is pure Pothos gone feral. Long trailing vines, low light tolerance, will absolutely creep across your bookshelf if you stop paying attention.

Grow this instead: Golden Pothos or Heartleaf Philodendron. Same energy, zero strangulation.

🫧 Gillyweed — breathe underwater (kind of)

Harry chews it before the second task and grows gills. Iconic.

Real-world cousin: it's pretty obviously inspired by seaweeds like Chondrus crispus (Irish moss). You can't grow it on your windowsill, but you can keep…

Grow this instead: a Marimo moss ball in a jar of water. It's a green velvet pebble that lives in a glass. Lowest-effort, highest-magic plant on Earth.

🌵 Mimbulus Mimbletonia — Neville's gross-but-loyal cactus

Neville's prized plant from Order of the Phoenix. Looks like a grey cactus covered in boils. Squirts Stinksap when poked. We love a chaotic queen.

Real-world cousin: equal parts Euphorbia obesa (the round one) and Lithops (the living-stones one).

Grow this instead: a Euphorbia obesa or any chunky little succulent that looks like it's plotting. Bonus points if it sits on a doily next to your Remembrall.

🌲 Whomping Willow — the tree with anger issues

Plant a tree, get a bouncer. The Whomping Willow swats Quidditch players, eats Ford Anglias, and hides a tunnel to a haunted shack. Standard willow stuff.

Real-world cousin: Salix babylonica (weeping willow) — drapey, beautiful, completely pacifist. Sorry.

Grow this instead: if you want drama on a leaf, try a Calathea Orbifolia or Maranta (prayer plant). Their leaves move — they fold up at night like they're sulking. Wild to watch.

🌹 Fanged Geranium — the bitey one

Mentioned in passing in Goblet of Fire. Looks like a normal geranium. Bites your finger off.

Real-world cousin: regular geraniums (Pelargonium) are sunny windowsill royalty and bite no one. The fanged version is, sadly, fictional.

Grow this instead: a windowsill scented geranium — lemon, rose, or chocolate-mint. Pet it; it smells incredible. No fangs included.

🎄 Bubotuber — pus, but make it a skincare ingredient

Slug-like stems full of yellow-green pus that, when properly squeezed, becomes an acne treatment. Hogwarts: where Hagrid runs the skincare clinic.

Real-world cousin: honestly… aloe vera. Squeeze it (gently), goo comes out, your skin says thank you.

Grow this instead: Aloe vera. The unofficial first plant of every Planthead. Free burn cream forever.

🌳 Venomous Tentacula — the plant in detention

A spiky vine with teeth. Tries to grab students. Banned by the Ministry. Same vibes as your one friend who keeps adopting Monsteras.

Real-world cousin: Venus flytrap (Dionaea muscipula) — actually carnivorous, actually has "teeth", actually sold at garden centres for £6.

Grow this instead: a Venus flytrap or a pitcher plant (Nepenthes). Feed it one fly. Become a Herbology professor.


So what's the point, Planthead?

Here's the thing: every plant in Harry Potter is just a regular plant wearing eyeliner. Real plants do move (Marantas pray, sunflowers track the sun, Mimosa pudica literally folds when you touch it). They do defend themselves with toxins, thorns, smells, and traps. They do heal us — aspirin came from willow bark, painkillers from poppies, antimalarials from sweet wormwood.

We don't need a wand. We need a windowsill.

Now go water something. 🌿
