You and I know it as a China doll because Radermachera sinica, also known as a serpent tree or emerald tree, is native to Asia, specifically the South and East where the climate is warmer. This plant can reach a height of about 30 feet, is more robust, has a graceful appearance, and grows without much difficulty even though it takes some time. It can grow to a larger size and is a mature height. They generally grow 5 to 6 feet indoors, and you basically need to shape them. Because the branches are close together, they could appear shrubby and compact. Before planting china doll plants in your yard, learn more about how to take care of them.
