‘The Prince of Wales will today open the only public garden in Britain to be allowed to grow cannabis.
The Prince will officially open the second phase of The Alnwick Garden, in Alnwick, Northumberland, which includes the UK’s only public poison garden, growing plants such as cannabis and coca under lock and key. [..]
The first phase of The Alnwick Garden, which has cost £35.1 million ($A82.04 million) to construct, was officially opened by the Prince in October 2002.
This afternoon, he will view the second phase of the project, which also contains the world’s largest wooden tree house, a unique set of water sculptures that combine physics with the arts and an imposing pavilion designed by architect Sir Michael Hopkins.’
