Black Horehound

Black horehound is a course or rough plant. The stem and leaves are dark in appearance and hairy too with a pungent and disagreeable smell.

Not only is the plant 'rough and ready' it grows in rough places. It can be found in waste places and on hedge banks where little else will grow. This is a tough character, a survivor perhaps. You would not want it your garden and you are best leaving it alone if you see it and yet it is quite harmless.
