China Doll Gone Wild

See that two story plant growing in the corner of the little planter that runs under the window? That is what is known as a 'China Doll' plant (Radermachera sinica) that is most well known as a small house plant. It was here when we bought the house and I have it cut down to about the height of the door once or twice a year. I do not fertilize it and it gets what little water there is from the automatic sprinkler in the planter. It just grows like crazy!
