They really love Coleus a lot since I saw them being used at 3 different places already. In this area, they planted them in containers that were either floating on the water or were placed just above the water.
Then the huge pond at the lowest level beside the lawn had a fountain that was turned on just when we walked past it. Because of the refraction of light through the water droplets, there was a small rainbow right across the fountain.
At the center was a rock island spotting lots of Iris birds that appeared to be suntanning.
