Prior to 1994
The Herbivicus spellbook is a book containing information on, and instructions of how to perform, Herbivicus. It was owned by Professor Pomona Sprout, who kept it in a garden of the Hogwarts greenhouses at Hogwarts Castle. Harry Potter, Ronald Weasley and Hermione Granger later came across it during the 1994–1995 school year and used it to learn the spell, which proved valuable against the ungrown plants which can be found all over the Hogwarts grounds.
