World's deadliest garden where no humans are allowed

The Poison Garden located on the grounds of Alnwick Castle in Northumberland, England is the deadliest garden in the world

In the Poison Garden, you can admire the plants with your eyes, but you're not allowed to touch or smell anything, because every plant in the garden is poisonous, and can possible even kill you

The garden was created in 2005 when Jane Percy, the Duchess of Northumberland, wanted to show people the scariest plants around

There are over 100 plants in the Poison Garden, and they're all wicked in some way.

Oddly enough, many of the plants found in the Poison Garden can be found right in your backyard.

Some of the narcotic plants, like poppies, cannabis, and tobacco don't sound so bad. But some plants sit behind caged because they're so deadly

The head gardener, Trever jones, even has to tend the garden wearing a face shield, gloves and protective bodysuit just to get around
