This 'appeared' and grew in a bucket of old cactus compost stuck in a quiet corner - I thin it only appeared this spring but it could have been there last year too, so it could be an annual or a biennial. I've left it alone out of curiosity as I didn't recognise it. Today it has flowers appearing.
The leaves are quite pungent if you squeeze them.
Stem and leaves slightly fuzzy.
