Common hemp-nettle (Galeopsis tetrahit)
Despite its name, the royal nettle is not a nettle! It is a false nettle, easily recognizable by its square stem and the presence of a swelling beneath the nodes (at the leaf insertion points). It is hairy but not stinging. It can reach up to 80 cm in height and has purplish (pink) flowers, speckled with yellow or white. They are grouped together and form a crown of spines: this is the calyx. Flowering occurs from July to October. Like the rest of the nettles (true or false), it is a undemanding plant: it is found in hedges, clearings, along paths or even in fields.
