There's not a long living evergreen quiet like the Canadian hemlock
The Canadian hemlock, Tsuga Canadensis, is a magnificent, versatile, long-lived tree that will add beauty and value to your property. Also known as the Eastern Hemlock, it grows in Zones 3-7, preferring well-drained, slightly acidic soil. As a specimen tree, the Canadian hemlock will mature at 40-70 feet with fragrant, blue-green needles on branches extending to the ground.
Planted closely together, the Canadian hemlock will quickly become a thick, dense privacy screen or hedge. These trees respond well to shearing and can be maintained at the desired height. As a bonus, the Canadian hemlock is shade-tolerant.
Even the smallest property can enjoy Canadian Hemlocks. Dwarf cultivars, such as ‘Cole’s Prostrate,' look wonderful as a foundation planting or weeping over a rock wall, maturing at less than 2 feet tall and 4-5 feet wide.
Whatever variety you choose, the Canadian hemlock will delight you for many years. They have size; they have large canopies, and they can provide you with large amounts of green color year after year. In most locations, they will stay green throughout the winter too.
