Looks like a Moroccan or pineapple broom, Cytissus battenderi

Yes, I agree. Smells lovely!

Yes I also agree, its a lovely shrub/small tree.

Wow! I want one... Never seen one grown like that before. Gimme gimme.
I have to give it a go.

Thanks everyone - I want one too!

Hi, I agree with the identification, but would question the hardiness of these, I know most sellers say they're fully hardy, but I'm fairly sure that they're only frost hardy, down to about 23f, Derek.
