Valeriana officinalis is a plant native to Europe and some of Asia, although it has migrated to North America. Muggles are aware of its existence, however many are unaware of its powers. The Valerian Root possesses sedative powers, and its sprig is used in several sleeping potions. The root is anxiolytic, thus it is also used in calming droughts and potions. Perfumes make use of the strong smell of the sprig (noted to be like a mix of cherry and vanilla), and the root itself is often worn by grooms at weddings, to ward off the envy of the elves. (This custom is still used today by wizards in Eastern Europe).
Valerian may grow to be five feet, and forms bunches of attractive white flowers. At least seven hours of sun is required to keep healthy. Root division and seeding are effective ways of starting the growth of a new plant. The seed should be planted in soil with a pH level of 4.5–5.0 (very strong acid), about 1/8 of an inch down. Valerian Root ought to be harvested in the fall, or in the spring. It is important to keep the plant out of the way of cats, who are just as attracted to the root as catnip.
The Valerian Root (and springs) is an important part of the Draught of the Living Dead and the Forgetfulness Potions.
