Whenever I look at the White Popinac flower up close it reminds me of the images of microscopic life forms taken with a powerful microscope. The flowers are these little (2cm diameter) balls that are creamy white with a greenish tone toward the inside. The image above illustrates what they look like far better than my descriptions.
The White Popinac is native to Mexico but has been introduced into many other countries for a variety of purposes. Its uses range from a simple ornamental tree for its unique flowers to firewood to livestock feed and as a tree that is good for the environment.
It is not a very big tree. Of the ones I have seen none is taller than 5 meters (16 feet).
