Can anyone identify this plant please?
Isle of Wight,
United Kingdom 
I know this is an Acacia, and I had the opportunity to buy one last year at an open garden event at Northcourt House on the Isle of Wight, I saw one yesterday when we were out. It has the flowers of the normal acacia, but the leaves are triangular

I've seen this one growing in a Yellow Book garden in northwest London

Thank you for all your help, i'll check it out on the tinterweb later and hopefully when the open gardens thing sets off on the IOW the plant sellers will have more to sell this year.

I think it's Acacia cultriformis, Andrea. (RHS book description and photo!)
