This was a huge tree. Common names are "Tree Hibiscus" , "Cotton Tree"......Latin name: Hibiscus tiliaceus. The bright yellow flowers look just like Hibiscus and they are very short lived. They fade to burgundy red color before falling. But the fading flowers look just beautiful and new, it's wonderful to see flowers in two colors in one tree at the same time. And look at the ground under the tree, only red flowers are lying dead there.
