Please can you identify the attached shrub/tree found as a self set in SW Hertfordshire? I have been unable to find any relevant information in my various books.
Thank you to all the people who replied to my question. All answers were most helpful.

It looks like Goat Willow, this seeds around freely and will grow into a large, rather boring tree.

But it has nice "pussy willow" catkins in spring

The leaves and stems look remarkably similar to my Kilmarnock Willow, but it has weeping branches.
