On closer inspection I noticed that the plant had serrated leaves, was of medium height (50 cm) and, to my surprise, had a sharp sting. I was keen to find out what it was and, after taking a picture and searching for similar plants on iSpot, I was able to ascertain it was Urtica dioica, commonly known in England as the stinging nettle.
