We have a wild area at the bottom of the garden with a large boggy section in woodland. At the back, up against a dry stone wall, there is a lot of dog's mercury growing strongly and I've just let it spread behind the other plants. I wonder now, though, if I should get rid of it, on discovering that it's very poisonous both to humans and dogs. We have young grandchildren and I know the risk of them eating it is very small but it's a bit of an anxiety. Sorry, can't seem to rotate photo, even though the original is upright. Any opinions appreciated.
