Every Chinese garden has some type of rock element. Some designers opt for a simple rock garden, while others construct miniature mountains from an assorted collection of rocks.
Rocks are chosen based on their shape, texture, substance, color and softness.
Limestone rocks that have taken strange shapes due to erosion are among the most valued rocks for Chinese gardeners. Some rocks are deliberately immersed in fast running streams so that they are scoured for the effects.
Back in Hong Kong, in the Nam Lian garden, there are also a good display of rocks in the garden. Again, the main elements of the garden being rocks, trees and lakes or water features. Some of course have pavilions or bridges too.
