White Paper Flowers
This plant is a white Bougainvillea. It's sometimes also known as "paper flowers" because the bracts are thin and papery. In this case, the bracts are white in color. Bougainvillea is quite common in Malaysia due to its tropical and warm climate.
This pic was taken at the back of my home. While this plant is relatively small, I've seen some Bougainvillea which can grow out of control just like my other home in Seremban. However, if it's well maintained by proper trimming and shaping, the plant can look really good.
