Solved Weed identification help please

Hi all, I’ve just moved house and am new to garden ownership. I’ve been advised to leave the garden to see what grows. I’ve seen daffs, bluebells, crocuses and tulips amongst many others, so I’m very pleased to watch it. However I’m seeing a lot of these with reddish stalks in the attached pictures. Does anyone know what they are please? I assume they are weeds and have hooked some out but if anyone could give it a name (and then I know whether to weed or not to weed...) I’d be very grateful. Thank you in advance!

 

They're of the willow herb family, probably purple leaved willowherb. The stuff in the last photo underneath is bittercress, hairy bittercress I think

 

Great, thank you!
My daughter enjoyed the explosive bittercress. I look forward to the seeds growing more of it!
