Swedish Aspen (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. 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. Used for small yards, as a screen or a vertical accent. It has none invasive root systems and is cotton-less. The fall color can range from orange to red. This aspen is an excellent tree for lining driveways or group plantings.
