Thank You

Not sure of the name, but the first one is a 'weed'. The second one looks like a willowherb - also a weed (take it you're talking about the plant in the foreground with the PALE pink flowers). Third one is a rush of somekind - the pith inside was once used for wicks in lamps - also a weed in a garden (unless it's a bog garden), and not sure what the last one is - but it doesn't look like a healthy garden specimen!

 

I would consider them all weeds

 

If you dont like them, they are weeds, if you do, they are plants.

Deciede yourself if you want them or not.
