2 unknowns in planter

Hi, there's two unknown plants among my Lobelias and Violas/Pansies. It is the browny coloured plant with pink flowers (top left) and the small 3-leaf plant bottom left.

I think I also had a chickweed type plant in there but I removed them.

P. S. I've just noticed I've a second "3-leaf plant" amongst the biggest green Viola leaves (centre).

The brown/green plant isn't a Herb Robert is it? They are in the near locale.

Thanks

The brown/green plant looks like a rose bay willow herb....

...the other one, a buttercup of some kind?

 

1. Agree willowherb ..there are many different ones.
However not Chamaenerion angustifolium...common name rosebay willowherb...see pics below.
