Wild flower growing near several veteran trees. Possibly Bush Vetch.
No interactions present.
Not a Bush-vetch. Looks very much like a member of the dead-nettle family (Lamiaceae) but not one I know. Could be a garden escape (although knowing me its probably something native, obvious and common).
... nothing more than hedge woundwort (Stachys sylvatica), but in the absence of a view of the foliage I'm not sure - the inflorescence is rather more leafy than usual.
Reasonably sure its not S.sylvatica - flower form and colour looks wrong.
