The landscape company told us that the type of flowering plant that I want for the hanging planters on the long wall is called a Bougainvillea. The Bougainvillea is very common in Malaysia because grows extremely well this climate. Here are some examples of the plant I found online. I am thinking of going with a dark orange color. I am even thinking based on some of these images, that we might try some in the second story planter in front of the big window because it seems like they can grow down quite well.
