Cytisus battandieri aka the Pineapple Broom. One of my absolute favourites
I had one on a pergola years ago - when in flower there's a strong scent of pineapple and the silvery leaves look great when not in flower
Thanks Dovefromabove and Pete8 for your quick replies, I'm so please you recognise it and I now have a name.
I agree it's a lovely tree I have never seen before.
I loved mine as well but it died the year of the really hard winter we had in Scotland a few years back.....They are a bit tender.
