Help to identify a plant.
This plant has arrived in my garden. I have let it flower to aid identification but have no idea whether it is friend or foe. I have never seen this in any of my friends gardens or in any garden I have visited but the bees seem to love it. It has quite a strange scent - like mild discenfectant and the stems are too tough to break by hand. It has grown to about 3 ft.high. When it first appeared I thought, by the shape and feel of the leaves it was a fox glove but now its grown it obviously isn't. Would love to here what you think so I know whether to compost it or not before it sets seed. Thank you
