Spiky flower tree

What kind of tree is this? Has these amazing blossoms.

A hard blip choice today, between this sort of sentimental image and a pic from a balcony overhead of some people eating at a restaurant. Kind of apples and oranges. I was fond of the idea of the diners, but none of the images worked out quite right. Sometimes you fall in love with a concept, but it doesn't deserve your love.
