Pigweed (Amaranthus)

Observation - Pigweed (Amaranthus) - UK and Ireland. Description: This plant had a distinctly minty smell when the leaves were crushed so I'm sure it's a mint. My first thought was Corn Mint but it was too big for that - not much short of a metre tall - hence this suggestion. Edit: Changed to match Spins' ID. Many than

This plant had a distinctly minty smell when the leaves were crushed so I'm sure it's a mint. My first thought was Corn Mint but it was too big for that - not much short of a metre tall - hence this suggestion.
