Duke Ferol has prohibited the cultivation of the narcotic Drudanae plant, except by special dispensation. Since this is a crossbred species that cannot survive in the wild, the plant has therefore become very rare. Drudanae needs lots of light, a warm (preferably indoor) atmosphere and regular watering (although not to excess). Keep in a bright location indoors during the winter. In summer, if warm or hot move outdoors to a sunny or only partly shaded location.
