Awesome! How about Poison Hemlock, Monkshood, Mandrake (Old World/European as opposed to 'wild' Mandrake aka 'Mayapple') or Henbane!? Check out the fun little book called 'Wicked Plants' by Amy Stewart (if you haven't already.) There's a small old church nearby that has the most beautiful golden yellow Brugmansia trees in the front. Stunning hanging trumpet flowers! Found I had this bookmarked: http://www.thepoisongarden.co.uk/default.htm Good luck...
