Weed identification needed

[taff]

I've been back through 6 pages of this bit, couldn't find a similar weed, and I've also looked on common weeds sites, again, couldn't find it.
Of course, that may be because I can't see for looking but enough ramble, does anyone know what this is? The frondy thing on the right.

If it has silver backs to the leaves it's silverweed! Has a small yellow flower when it gets going too. Nice little thing in my opinion.

Hooray!!!
You have no idea how long I've been looking to find out what this thing is.
It's roots are just like bindweed only brown, it'll grow from the tiniest bit, and it's completely infested the lawn, and is trying ti's hardest to get into my beds.
It is pretty, but it's also fast taking over the world!!
Thank you very much flummery, looks like I need a goose...

I've never seen that before !

You get it a lot on country verges. We've got some in one of our Britain in Bloom beds. We tried digging it all out and I can confirm it's jolly hard to eradicate. We have now decided to pretend it's deliberate!

Wayhay, a weed that isn't infesting my plot!!!!! Knew I'd find one eventually......

I'm consoling myself with the thought it's partly herb....
It's not working though....
