Description
Selected from a mature stand of native trees by Bill Heard in central Iowa, this tree was chosen for its upright, narrow shape. 'Greencolumn' grows with a strong, straight trunk and maintains a good central leader. it matures at about 65' with a 25' spread. Unlike most trees with a narrow shape, it has a wide branch angle making it resistant to storm damage. The leaves are light green; fall color is yellow.
