Behind the scenes
- On Pottermore, it is revealed that a single company, Floo-Pow, was licensed to make Floo Powder in Britain, and that the composition of its product was a "closely guarded secret" no one had managed to figure out. Thus, this plant must be considered non-canonical, as it is unlikely its existence or practical application would be widely known, much less taught in Herbology class at Hogwarts.
