The usual suspects

I wonder if some kind soul out there might be able to assist me with the identification of some plants (whose images appear below) that seem to be all too prevalent in our garden (yard). I have endeavoured to ascertain their particulars but thus far without success.

Should the gentle reader be tempted to advise me simply that they are ‘weeds‘ – then my gratitude might seem somewhat muted. That much I already know!

Thanking you in anticipation…
