The weed, Enchanters Nightshade (Circaea lutetiana) grows, I understood in dark damp places and flowers in Summer? Yet here in Kent, UK it appears to be in flower in Winter and is growing in a sunny dry place? Is this a different plant? Any help appreciated!
Your plant is not Circaea lutetiana....Enchanters nightshade...which only grows in damp shaded wood..in winter it vanishes completely. Circaea lutetiana - Google Search It looks like Mercurialis perennis..Dogs mercury. But this is another woodland plant and normally disappears in winter and is the first to emerge in the spring. I wouldn't expect to see it in full flower in January. Mercurialis perennis flowers - Google Search
