Tsuga canadensis 'Kelsey's Weeping' is an irregular, upright weeping selection of Canadian hemlock with stout, randomly growing, widely arching primary branches, horizontally spreading secondary branches, and long, strictly weeping shoots and branchlets. Foliage is species-typical bright medium green in color. After 10 years of growth, a mature specimen will measure 7.5 feet (2 m) tall and 10 to 12 feet (3 - 4 m) wide, an annual growth rate of 6 to 8 inches (30 - 35 cm), mostly outward, especially in younger plants.
This cultivar originated as a seedling selected in the late 1920s by Harlan P. Kelsey Nursery, Boxford, Massachusetts, USA. Some authorities have incorrectly listed this cultivar as 'Kelsey Weeping'.
