Is this a weed

Do you all think that this is a weed?
Really hope that it is . I thought it was self sown euphorbia but there’s no milky sap. 
It’s taking up too much space and I’ve got some alstroemeria that I want to plant in its place.

Got it!
rosebay willow herb. 
yes it’s a weed - got loads of it to yank out!
will be posting photos of alstroemeria once they get going!
