My guess would be...

1) Buddleia seedling
2) not sure but could be michelmas daisy (Aster). Could also be a Helenium.
3) Myosotis or forget-me-not

Good morning and welcome to Goy Dimond.

Yes the 1st on is Buddleia
Not sure the 2nd

And yes forget me not for the 3rd.

agree 1& 3
think 2 might be one of the shasta daisy types big white flowers yellow eye. leucanthemums they are called now.

Agree 1 & 3. 2 might be Shasta Daisy; or my first thought was Red Campion (Silene diociae)?

Thanks for your thoughts everyone..its great that you are all so willing to help. No. 1 plant wasnt found in my garden but was one of the seeds i found and kept from my mums garden when she passed away.. i really would love to know what it is :0) I havent attended to no. 2 pic yet so still looks quite messy. Now i am off to google all of your suggestions..wish me luck :0)) thanks again !

Definitely buddleia, number one: I would guess some kind of Leucanthemum for number two (My Esther Read looked just like this), and, as everyone else says, Myosotis for number 3. (your last comment has just popped up while I was writing!)

I agree buddleia, leucanthemum and myosotis.

The leucanthemnum could be divided in two with a sharp spade to increase your stock.
