"She leapt up and struggled against towards a damp wall. She had to struggle because the moment she had landed, the plant had started to twist snake-like tendrils around her ankles. As for Harry and Ron, their legs had already been bound tightly in long creepers without them noticing. Hermione managed to free herself before the plant got a firm grip on her. She watched in horror as the two boys fought to pull the plant off them, but the more they strained against it, the tighter and faster the plant wound around them."
— The Trio facing the Devil's Snare in 1992[src]

Devil's Snare was a magical plant with the ability to constrict or strangle anything in its surrounding environment or something that happened to touch it.[1] Devil's Snare did not seem to be common, but certain Herbologists had access to it.[1]


Hermione Granger: "Stop moving! I know what this is - it's Devil's Snare!"
Ron Weasley: "Oh I'm glad we know what it's called, that's a great help"
Hermione Granger: "Shut up! I'm trying to remember how to kill it!"
Harry Potter: "Well, hurry up, I can't breathe!"
— The Trio falling victim to the Devil's Snare[src]

The Devil's Snare strangling Ron Weasley

It was composed of a mass of soft, springy tendrils and vines that possessed some sense of touch, and resembled the Flitterbloom.[4] This plant used its creepers and tendrils to ensnare anyone who touched it, binding their arms and legs and eventually choking them. The harder a person struggled against Devil's Snare, the faster and more tightly it bound them. If the victim was able to maintain their presence of mind and relaxed, the Snare would relax its grip on them. Struggling or resistance to Devil's Snare would cause the plant to exert a greater force of constriction. Devil's Snare preferred a dark, damp environment. It would stop its movement in the environment in front of bright light and would recoil away from the heat of fire, so a well-placed fire or light based spell such as the Bluebell Flames, Fire-Making Spell, Wand-Lighting Charm or Lumos Solem Spell would effectively drive it away from its victims.[1]


1984–1985 school year

Jacob's sibling: "What is that thing?!"
Merula Snyde: "A deadly plant called Devil's Snare. Some fourth-year Slytherins showed it to me when I first arrived."
— Jacob's sibling trapped with Devil's Snare[src]

In 1984, Merula Snyde was shown a Devil's Snare in a storehouse by fourth-year Slytherin students shortly after her arrival. Later in the year, she tricked Jacob's sibling into entering the storeroom under the belief they were getting Pickled Slugs for Professor Severus Snape, in order to recover lost house points. Merula was jealous over the praise the student had received in their initial classes and angry that they had stopped her from bullying Ben Copper.[5]

The plant attacked and the student was able to briefly hold it off with the Wand-Lighting Charm while calling for help. They were rescued by Rubeus Hagrid.[5]

1985–1986 school year

Fang ended up in the same room as a Devil's Snare. Hagrid told Jacob's sibling to use a Fire-Breathing Potion to safely rescue the dog.[6]

1991–1992 school year

Hermione Granger: "Devil's Snare, Devil's Snare ... What did Professor Sprout say? It likes the dark and the damp - "
Harry Potter: "So light a fire!"
Hermione Granger: " Yes - of course - But there's no wood!"
Hermione Granger: "Oh, right!"
— The trio learning how to defeat the deadly plant in the Underground Chambers[src]

Hermione burning the plant with the Bluebell flames

In 1991, Professor Sprout placed a large Devil's Snare as the second defence of the Philosopher's Stone, just below the trapdoor guarded by Fluffy. In 1992, Harry Potter, Hermione Granger, and Ron Weasley were caught in the plant when they attempted to prevent the theft of the Philosopher's Stone.

Hermione managed to quickly free herself from the plant's grasp, but Harry and Ron quickly became bound by its tendrils, and started to suffocate. Hermione instantly identified it but initially struggled to remember how to kill the plant from she had learned in Herbology. Thankfully, she remembered the plant's preference for damp and darkness, so she set the plant alight with the Bluebell Flames, freeing both Harry and Ron from the deadly plant.[1]

1995–1996 school year

"As his speech and mobility improved, Healer Strout encouraged Mr Bode to look after the plant himself, unaware that it was not an innocent Flitterbloom, but a cutting of Devil's Snare, which, when touched by the convalescent Mr Bode, throttled him instantly."
— A spokeswizard for St Mungos regarding the death of Broderick Bode, reported in the Daily Prophet[src]

In 1995, Broderick Bode, an Unspeakable working for the British Ministry of Magic, was a comatose patient at St Mungo's Hospital for Magical Maladies and Injuries, after having been Imperiused into attempting to steal a prophecy from the Department of Mysteries. When Bode began to recover, a Death Eater sent a potted Devil's Snare to the hospital, disguised as a Christmas gift, in order to silence him.

Healer Miriam Strout foolishly mistook the plant for a harmless flitterbloom[4] and left it by his beside his bed, despite St, Mungo's strict guidelines about decorations in the wards. She believed that taking care of it himself may help with his recovery. It subsequently asphyxiated Bode later that night.[2]

"Tentacula. Devil's Snare. And Snargaluff pods ... yes, I'd like to see the Death Eaters fighting those"
Pomona Sprout planning her own unique defences for Hogwarts Castle[src]

In 1998, during the Battle of Hogwarts, Professor Pomona Sprout and Neville Longbottom placed Devil's Snare around the castle of Hogwarts to attack approaching Death Eaters and Giants, along with the similarly dangerous Venomous Tentacula and Snargaluffs.[3]

  • In the film adaptation of Harry Potter and the Philosopher's Stone, Hermione and Harry were able to escape the Devil's Snare by simply remaining calm. When Ron began to panic, Hermione saved him by casting Lumos Solem. The Snare also roared in its appearance when exposed to Hermione's spell.
  • In the film adaptation of Harry Potter and the Goblet of Fire, the Hedge Maze attacked the Champions during the third task of the Triwizard Tournament. Some roots attacked Cedric, it may be related to Devil's Snare. Eventually, it kept strangling Cedric, then Harry freed him from it.
  • In Harry Potter and the Deathly Hallows: Part 2, Devil's Snare can be seen inside the Room of Requirement growing out of a glass case at the bottom of a column and growing toward the ceiling.
  • In LEGO Harry Potter: Years 1-4, the first year Herbology students have a lesson on Devil's Snare. The plant gets out of control and captures Ron, as well as stealing Pomona Sprout's wand, requiring Harry and Hermione to destroy the plant with the Lumos Solem Spell.
  • In the PS2, Xbox and Gamecube versions of Harry Potter and the Philosopher's Stone, the Devil Snare actually heavily resembles a giant Venomous Tentacula but coloured blue instead of green (and it is defeated the same way, using the Severing Charm and the Fire-Making Spell respectively).
    • This also applies to its portrayal in the GBA version, but it instead fires seeds continuously from its mouth if within a specific range and can only shoot them diagonally (unless Harry is very close to them then they'll shoot perpendicularly); unlike the Venomous Tentacula, it can be defeated by jinxing the nearby torch platters with Flipendo to make them tumble and burn the Devil's Snare.
  • In the PS1 version, there is a circular chamber containing the Devil's Snare. Ron and Hermione run to a side and a part of the Devil's Snare forms a wall, blocking them from the rest of the circular chamber. There are several tree-like branches which are green that spring up when Harry gets to close and attempt to squash him. Harry must cast the Knockback Jinx on the correct stalk (indicated in light green) in order to kill that stalk and bring the central stalk up, in which Harry must use a fully charged jinx at it to defeat part of its life. After defeating it each time and then setting the plant alight with the Fire-Making Spell to kill it, the Devil's Snare blocking Ron and Hermione will wither away which allows them all to proceed.
  • Devil's snare is also another name for datura stramonium.
