Bompas and Parr will also be hosting a 'Plant Connoisseurs’ Club', looking at "unfamiliar, yet culturally significant plants" which guests will be invited to try.
Guest speakers will include Professor David Nutt, the former government drug advisor who was dismissed in 2009 over his liberal comments on drugs.
The endeavour is similar to a permanent display at Alnwick Gardens in Northumberland. Their Poison Garden is specially licensed by the government to grow a variety of poisonous and intoxicating plants.
'Intoxication Season' is on now and will run until the 12 October. Tickets can be bough here.
