I have been trying to discover the name of this flower for fifteen years. They are on trees that flower so high above the ground that you can only see them from a distance. Last year, I photographed a smaller variety next to the car wash in Ajijic. When I photographed this one at the Nueva Posada two days ago, it was from very far away but decided to use it today anyway. It was when I cropped it a bit that I suddenly remembered what the leaves remind me of. Sure enough, I finally identified it as a variety of schefflera called the flowering schefflera or octopus tree! Now if I can just remember it next time. (Also known as the schefflera arbicola.)
For Cee’s flower prompt.
