Rose Petal

"There are over a hundred species in the genus Rosa. Wizards and Muggles alike have been breeding garden roses for thousands of years. Thorn: Some love potions use more thorns instead of rose petals, although I personally have found the effects of these potions tend to be brief and somewhat unstable."

- Zygmunt Budge on the use of Rose Petals in Love Potions Rose Petals are the petals of a Rose (genus Rosa). They have magical proprieties and are used as an ingredient in Beautification Potions, and for Love Potions. Zygmunt Budge preferred to use the petals of a rose rather than the thorns in Love potions, as he felt that those made with thorns were of brief effect and unstable.
