The Columnar Swedish Aspen is a breakthrough in hardy trees for screening, or as a specimen tree. It forms a beautiful, upright column that can reach 40 feet, but it will always remain narrow and so it is ideal for restricted spaces. It is fast-growing, adding a foot or more every year, and its upright form means it never needs trimming to make a dense screen or a beautiful vertical accent specimen. The leaves are red in spring, green in summer and gorgeous shades of gold and crimson in fall. This tree is resistant to pests and diseases and does not produce messy seeds.
