What tree is this?

[wishywashy6]

We found this young tree growing amongst a very overgrown hedge in our garden. Now we've sorted the garden out and DP has carefully dug it up and replanted in a better position but just wondered if anyone could tell me what it is?
I've attached some pics of the leaves, hope they've worked!

Not entirely sure, but I think it is a variety of salix (willow). Are the leaves slightly furry?

Goats willow is prone to poppiing up everywhre.

There's an app you can download where you take a photo of plant and it tells you what it is, plantfinder I think.

Looks like lilac to me, but that's the second time tonight I've said that so maybe I've just got lilac on the brain (I've been doing a lot of pruning and clearing around our one the last few days - not pruning the lilac itself though, don't worry! - so been getting a good look at it).

@yamadori yes the leaves are slightly furry

Thanks all, I'll try plantfinder and see what that says.

@wishywashy6 Good idea, I agree with another pp that it is probably goat willow although willows have a tendency to hybridise so you might not find the exact thing.

Willow. Lilac doesn't have furry leaves.

The app said Goat Willow so we're thinking it's most likely that!
Thanks for all your help, I'm not very green fingered!
