I have this palm like plant right in front of the bungalow I am staying in which only flowers at night. During the day the buds look like they are going to burst open. As it becomes dark, the flowers open revealing these pink and white flowers. By next morning the flowers have all dropped to the ground.
My bungalow has a nice tropical garden and is at the foot of forest covered mountain, so all this weird and wonderful wildlife comes out at night.
