Northern Japanese Hemlock Tree

Northern Japanese hemlock is an evergreen conifer native to Japan, with glossy green needles marked by two pale bands underneath and small cones. It usually forms a broadly conical tree, while plants in colder, higher-elevation parts of its range can be shrubbier. The [American Conifer Society profile](https://conifersociety.org/conifers/tsuga-diversifolia/) describes its mountain habitat and shade tolerance, and the [RHS profile](https://www.rhs.org.uk/plants/18471/tsuga-diversifolia/details) confirms its name and family. ## Site and display Use this species where an evergreen structure is wanted and there is room for its mature form. It tolerates dense shade and grows in cool, snowy mountain conditions; the foliage and branching suit woodland or shaded conifer plantings. The [American Conifer Society](https://conifersociety.org/conifers/tsuga-diversifolia/) notes that plants at high elevations may have a more compact, shrubby form. ## Maintenance Water during establishment and extended dry weather, while allowing excess water to drain. Preserve the natural outline with only selective pruning. Choose a site with suitable light and space rather than assuming every hemlock has the same mature shape.
