Dog's Mercury (Mercurialis perennis)

Wild flower 

2/4/16

A poisonous coloniser of ancient woodland, dog’s mercury is quick to sweep over the wood floor, sometimes outcompeting more delicate ancient woodland species.

Dog’s mercury is not a showy plant and is easily overlooked, but it’s very common. It flourishes in woodland with a preference for living under oak, beech, ash and elm. Although it’s mainly a plant of ancient woods, it can colonise new deciduous woodland very quickly. It favours shady areas and can also be found in hedgerows.
