Kitty is right. Are you sure a gardener planted it? Thy're great ones for just turning up by themselves. I never introduced them here, my they are here now
Don't take too much notice of all the panic stories, just don't eat it and wear gloves if you handle it (like I don't) and all will be well. They are certainly not dangerous to wildlife or fish.
