Do you mean the photonext to your name?

Welcome to GoY Kath, you need to add photo to your questions before we can answer - if it is the plant on you avatar that is far too small to i.d.

There's a better pic in the Garden Pictures section.

No idea, we need a photo of the complete plant please.

If the bright green one next to the fern is the one you're referring to, it looks suspiciously like ground elder.

Could be Tugb.
