There are so many spectacular flowering trees, but the royal poinciana (Delonix regia) must be at the top for sheer extravaganza.
The first photo is of the tree on the other side of the road. It's not the typical shape, which is umbrella-like. The second photo, taken one block away, is more like it. You can also see two more further down, and in May and June, this is a common sight -- a tunnel of vermilion.
Poincianas (also known as flamboyants or flame trees) are true tropicals and I'm not sure how far north it grows, but probably not above Lake Okeechobee.
The first time I ever saw one I was visiting Guiana with my father. As I stood gobsmacked by the glorious sight, my poor old dad couldn't understand what I was talking about. Turns out that poincianas are all brown if you have red/green color blindness. Sadly, I also have the gene since I passed it on to my son. He can't appreciate them, either.
