Verbena

Verbena is a common flowering plant. Perhaps common in general, but not in the game. There it grows outside St. Lebioda's Hospital, and near the Druids' grove and Golem burial ground only. It is said to be also known as Vervain in Bullsville.

 * One of many "Old peasant women" in Murky Waters will give Geralt entries for Verbena, hop umbels, and finally bryonia in exchange for "something sweet" (Candy and Sugardolls work) or 80 each time.

While this plant grows wild and is quite abundant, it can also be purchased from various merchants including:
 * Anezka in Lobinden
 * Myron in the Kaedweni camp
