"A common garden plant that is known to bite or attack if not taken care of. Its fangs are used in many simple potions and in cooking."
—Description on seed packet at Dogweed and Deathcap[src]

A Fanged Geranium was a magical flower with sharp teeth.[1][2] Its fangs were used as potion ingredients, as well as in wizarding foodstuffs.[3] They are also an ingredient in the Strength Potion.[4][5]

This plant was covered in fifth year Herbology lessons in the 1988-1989 school year.[6]

This was one of the plants covered in 1995 as a part of the O.W.L. practical for Herbology. Harry Potter received a minor bite from one during his exam.[1]

There was widespread historical speculation that the Muggle War of the Roses actually started with wizarding neighbours arguing over a Fanged Geranium.[7]

Fanged Geraniums were mentioned in an advertisement for the Toots, Shoots 'n' Roots radio show that was printed in Rumours!. The ad copy asked, "Fanged Geranium nothing but gums?"[2]

Fanged Geranium seeds were sold at Dogweed and Deathcap.[3]
