Solved Willow or blueberry?

Hi everyone I'm unsure what I have here, first instinct was pussy willow but it's popped up about 3ft away from a couple of blueberry plants so I'm hoping it's the latter.

 

Looks a bit pale for a willow.

 

I'd say blueberry out of the two, but I'm not sure about the "popped up" bit! Don't they take a couple of years to get to that size from seed? Don't exactly know myself as I've only ever bought mature plants...

I'm using my phone at the moment so the pictures to small for my bad eyesight, I'm erring towards willow now, sorry but I'm on the fence at the moment.

 

Just had a look at the blueberries their leaves seem thinner.

 

Yeah, looking at bigger pictures now I'd guess willow.

 

Sadly....Weedy willow!
