1 metre tall. Sweet smelling. Round leaves. In coastal hedgerows on Gower peninsula.
No interactions present.
So not a 'wild' flower as such.
Thank you for the information.
I would consider it as a 'wildflower' albeit non-native and naturalised.
It was brough to the UK by the Romans as a pot herb (a good substitute for celery).
It is not widely planted and spreads quite easily by seed. It can be a big problem on coastal roadside verges shading out native species.

I couldn't find it in my wildflower books - so it's non-native which explains it. Wish I'd tasted it now - love celery!! I can see how it might be a problem, it was certainly a presence.
Thank you very much for taking the trouble to explain.
