The golden shower trees (Cassia Fistula) are very common here in Malaysia (the plant is native to India and Southeast Asia) and when they bloom with the whole tree full of yellow flowers it is a beautiful sight. I was fortunate enough to get up close and personal with the flowers at my eye level on a young tree recently to take a few pictures of the blooms as the tree normally grows up to 10–20 m/33–66 ft.
