A common Ash (for DD)

Ours are the same, no golden leaves, just lots of seedlings

It's actually in neighbours garden but right on the fence line & towers over everything.

Oh dear and they grow quite fast, I see there is a willow too.

Yes there is & again it's just on the boundary. Last early spring before they broke leaf, the neighbour got 2 tree men round to remove the lower branches from the ash & to also reduce the willow. They had all the proper gear, I was glad to see the ash branches go but I thought the willow looked awful when they had finished, they removed all the top branches but left 3 main trunks sticking up like huge telegraph poles. Can't tell what its like now as still in leaf.

Obviously an old Ash tree GF they do grow to be enormous trees, unless they get Ash dieback! the one I photographed was a young tree.....

Angela,
Or it could be F.'Jaspidea' Golden Ash

I had hoped our common one would die-back but it's still pretty vigorous!

That's typical isn't it, I wish our neighbours awful conifers would too, no such luck!
