Columnar Swedish Aspen
The Columnar Swedish Aspen, Populus tremula 'Erecta', is native to the forests of Sweden. This slender tree is great for smaller spaces, screens and along drives. It is probably the narrowest of the columnar trees. The dark green leaves have a lighter silvery-green underside providing both visual interest and a soothing sound in the breeze and tremble with the faintest whisper of wind, creating the same pleasant rustling sounds as the leaves of Quaking Aspen. It is well adapted to very cold climates, but needs adequate moisture. This tree is an excellent substitute for a Lombardy Poplar in cooler climates. It is best suited for small yards, as a screen or a vertical accent. It has none invasive root systems and cottonless. The fall color can range from orange to red. This aspen is an excellent tree for lining driveways, fence-lines, shelterbelts or group plantings. Somewhat adapted for street and boulevard planting, the Columnar Swedish Aspen will provide both visual interest and a soothing sound to the landscape. ... more
