I've walked by this tree many, many times but never noticed it until today. That only happened because it's flowering and the flowers are bright red and exotic and one was low enough that I caught it with the corner of my eye. I can't find anything like it in any of my tree books.
I went back a few days later and found seed pods all over the sidewalk and brought one home to draw. I have permission to go back and draw some more. There's a low branch with a blossom. I can't wait!
