Swedish Columnar Aspen (Populus tremula Erecta) is probably the narrowest of the columnar trees that we grow. Rounded leaves suspended on long petioles tremble with the faintest whisper of wind, creating the same pleasant rustling sounds as the leaves of Quaking Aspen. Swedish Columnar Aspen grows to a height of 40 feet and spread of about 10 feet. A good substitute for Lombardy Poplar, it is seedless and hardy through USDA Zone 2. It also thrives in milder climates, as evidenced by the tall specimen growing in our arboretum. |
