This tree has many names, such as Gold Rush Tree, Golden Shower Tree, Indian Laburnum, Pudding Pipe Tree and Cassia fistula. It's formal name is Cassia fistula, but most people call it golden shower. I like Laburnum and I call it Florida Laburnum. The Laburnum is a temperate tree that has chains of yellow flowers shaped like a sweet pea. The tropical tree stays in flower much longer then the temperate one.
