First i.d was Lucerne but looking at it closely, it does not have stalked flower heads and the leaves do not appear to be toothed.
No interactions present.
Thanks Mark for the i.d. I had it down as Lucerne but it just seemed different from my other ob which shows long flower stalks.
Having made the mistake of mixing two species in one ob. I didn't want to do the same again!
