In the wild, our native Pacific madrone grows into large noble trees. The majority grow 50-75 feet tall. However, In Humboldt County, California, (see black and white photo in the link below), one was found growing 96 feet tall by 113 feet wide; its trunk measured 24 feet, and estimated to be about 600 years old. I was in Humboldt County once; I believe they super-size everything down there. Unfortunately, the madrone was split into pieces by a windstorm on February 3, 2000.
