Canadian Hemlock will grow to be about 60 feet tall at maturity, with a spread of 30 feet.

It grows at a medium rate, and under ideal conditions can be expected to live for 70 years or more.
This tree performs well in both full sun and full shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type, but has a definite preference for acidic soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This species is native to parts of North America.
