Garden notes
The leaves and bark of Tsuga canadensis have a mildly pungent aroma. The bark of White hemlock (also known as western hemlock, Canadian hemlock or eastern hemlock) has been used in traditional fabric dyeing. Brown and brown are common colors produced with this plant. This species can survive very cold winters with annual averages as low as -40� Fahrenheit. It needs a bit of a cold spell with temperatures below 15� Fahrenheit to do its best. This plant does very well with hot summer days. Full sun to full shade is needed for this species to do its best. It prefers moist, well drained soils.
