Opinion
"
Sargents Canadian Hemlock could be one of the most beautiful evergreen shrubs. The soft and short needles attached on the weeping branches can reach the ground. It is generally an excellent specimen and also an erosion control evergreen shrub.

| Propagation |
| It can be propagated by cuttings from the woody stem of this species’ cultivar of eastern hemlock, especially in summer. Remove the soft tip growth, and cut into 15–30 cm long. Make sure all cuttings are clean above a bud at the top. Keep moist in dry times in summer. It won’t be successful if heat, rooting hormone, and moisture levels don't meet the demands. |
