There is a rather vicious rose bush in a deeply forested area. The red roses that bloom on this bush can be harvested each summer for 6 pawns of herbam vis. The bush is extremely hard to harvest from and craves human blood. In fact, it needs it in order to bloom each year. The thorns the bush produces are particularly nasty and the person picking the roses will end up bleeding. Anyone who harvests from the bush will suffer a light wound. If the bush was not "fed" the previous year, it will not bloom that year.
