Help ID Plant Please

Maybe one of the purple-leaved forms of snakeroot (Actaea)?

Thank you Tugbrethil .... I'll take a look in my plant encyclopeadias tonight. 👍

It looks like Sambucus Nigra common name black lace or black Elder

I thought it was the dark form of the common cow parsley? Anthriscus sylvestris Ravenswing Black Cow Parsley

If it grows into a woody bush, it is the elder, but that pot looks kind of small to support that. If the flowers are in a kind of wiggly spike, it's the snakeroot. If the flowers are a flat topped cluster, it's likely to be the cow parsley. The elder also has ftat topped clusters, but it isn't going to bloom if it is pruned to the ground every winter.

Thank you Tugbrethil, Thrupennybit and Honeysuckle for your suggestions, I'll try and do a bit of research myself now I have some pointers. I will also ask my daughter about the flowers.

I think the Anthriscus is the most likely.

Thanks very much Karen... Best wishes! x
