"She whipped out her wand, waved it, muttered something, and sent a jet of the same bluebell flames she had used on Snape at the plant. In a matter of seconds, the two boys felt it loosening its grip as it cringed away from the light and warmth."
—Hermione using the spell against the Devil's Snare[src]

Hermione placing the Bluebell Flames in a jar

Bluebell Flames (incantation unknown), also known as Cold Fire,[5] was a charm that created magical blue flames with unique properties.[4]


Bluebell flames were bright blue in appearance and were waterproof.[6] Not as dangerous as real fire, these magical flames could be touched, penetrated and held without it burning the holder, though it was known to singe materials such as clothing and plants.[4] As such, it might be safely carried in small objects, such as a jar, without the object being damaged.[7] These unique flames could also be directed to a desired location by its caster, and return to its original position.

Behind the scenes

Bluebell flames

A jar of bluebell flames

  • In the film, this spell was replaced by Lacarnum Inflamari when Hermione attempted to distract Snape by igniting his robes, and Lumos Solem to attack the sunlight and heat sensitive Devil's Snare.
  • In the seventh film, Ron tells Harry that he always liked these flames. In that film, the flames are depicted as normal, reddish-orange fire which levitate without a surface to burn on, though in the book they appear blue, as in the other books.
  • The video game adaptions of Harry Potter depict this fire as similar to the Incendio. However, these appearances must not be considered valid, as Incendio produces normal fire, not the bluebell flames that this spell creates.
  • Hand-held flames may be a variation of this spell, as both produce flames that can be safely carried.
