What's this amazing tree

I saw it in a local park and had to take a photo. Can anyone identify it?

Thinks it's a Handkerchief Tree.

Just googled. Official name Davida Involacrata.

Thanks User! Hooray for the power of Mumsnet.

Not sure if you were asking because you are intending to purchase one. If so buy a mature specimen because they do not flower until they are about 20 years old
