A plant known under many names:
Fellenwort, felonwood, poisonberry, poisonflower, snakeberry, are the english names I found (there are most probably way more) and some of the German names are Bittersüß (bitter sweet), Hundbeere (dog’s berry), Mäuseholz (mice wood), Mausholz (mouse wood), Natterholz (verbatim: adder wood, but “Natter” is also a synonym for a snake in general), Saurebe (hog’s tendril), Stinkteufel (stinking devil), Süßstoff (sweetener), Teufelsklatten (devil’s claws. Klatten is the Middle High German word for “Krallen” meaning claws), Waldnachtschatten (that is the official name, I guess).
All parts of the plant are very poisonous!
Just if you need to know 😉
