Alnwick Poison Garden
Tucked away in the Northumbrian countryside, there is a special garden where every plant can 'kill' you. Here, visitors can see a lot of plants and flowers that are colorful and seem normal, but they are all extremely toxic. The area is home to more than 100 species of noxious plants, many of which are deadly poisonous when eaten or harmful even when smelled. According to Mr. Trevor Jones - the garden manager, the poplars make you fall asleep forever. Similarly, four poison ivy in the garden could be enough to kill a child.
The boundary of the poison garden is separated behind a black iron gate and is only open to guided tours. Even some tourists sometimes faint from inhaling toxic fumes.
