Can someone please identify the unknown plant in the middle for me,
before my brain explodes with the effort ? I know it's going to be
something quite common, probably, but I cannot remember what it is (I
planted the damn thing too!). Thank you to anyone who knows and posts.

Hi Clare

One useful thing to do is to search on google but select images - you
should get lots of photos and hopefully you will be able to compare them
to your plant and get a definite ID!

Good luck
