Tsuga canadensis 'Ashfield Weeper' is an irregular, weeping selection of Canadian hemlock with long, arching branches, and pendulous branchlets densely covered with dark-green needles that are bigger than those typical of the species. The tree's smooth, gray bark combines with its swooping branches, draping branchlets and small cones and buds to create, over time, an elegant look in the landscape. If staked, a mature specimen will measure 8 feet (2.5 m) tall x 5 feet (1.5 m) wide after 10 years, an annual growth rate of 6 to 8 inches (15 - 20 cm).
This cultivar originated as a random mutated tree, found in 1964, by Ormand Hamilton alongside a roadway in Ashfield, Massachusetts, USA.
