Well, your flowering plant is the weed 'scabious'. Sorry! But good (?) news! The grass seed you refer to would be from one of our lovely native spear grasses. Well named, no? Quite a pretty grass but you certainly want to avoid getting the seeds lodged in your clothing, or skin, or dog, for that matter.

Thanks for that Leanne - I did wonder about the flower. The spear grass is *very* aptly named, and the seeds are most unpleasant.
