It has a willow look about it? But there are so many, I wouldn't like to guess.

Looks as though its planning to be a tree anyway.

I agree - it looks like the willow that self-seeds into my garden from the school site over the wall, but I don't know what variety, I'm afraid.

i know it as crack or goat willow

Yes - goat willow, that's it.

many thanks to you all for replies my big sister will think me very clever if only fo a moment .
