Alnwick Poison Gardens. England
Located in the town of Alnwick, Northumberland, England, next to Alnwick Castle, the garden is home to some of the most poisonous plants known to man: Nux vomica (the source of strychnine), hemlock, ricinus communis (source of harmless castor oil but also deadly ricin), foxglove, atropa belladonna, brugmansia, and laburnum. There are even specimens of cannabis and coca plants specially protected from the public, and for which they have a special license. You wouldn’t want your children gamboling around some of these plants.
