should they stay or should they go?

Any ideas if these are weeds or whether they'll turn into anything worth keeping?

Many thanks

 

Bin the first 2 = dock and willowherb
but enjoy the last one = forgetmenot,
I think,

... Is there a foxglove plant, lower right, in the last photo?

 

well spotted

 

The first plant could be horseradish, check the root before you decide to throw it away (assuming you like horseradish).

 

its dock leaf , I have horseradish growing in the garden

 

Thanks guys The ones in the green box were the most puzzling, that was the box I grew pumpkins in last year and it had no weeds or anything else in it so I'm presuming they've probably been spread into it by birds or something. Will get weeding tomorrow

 

Dock, willowherb and forget-me-not. I think that's a foxglove too, though it might be Verbscum. In any case I'd say it's a keeper. It's a biennial, meaning it's done the hard work of growing from tiny seed for one year and will now grow rapidly and flower for you this year.
I wouldn't personally bother with forget-me-not, as the wild type has small flowers and lots of foliage. Willowherb has light seeds spread by the wind so it gets everywhere and looks lovely and green when young. But is a weed, especially the species if it's one of the species with a tiny flower.
