The natural distribution of Tsuga heterophylla is from southern Alaska to northern California where it is an important forest tree. In Britain it is planted in rich soils in semi-shaded situations resulting in fast growth but alas the plant is susceptible to heart rot.

Some of the first plantings occurred at Scone, Dupplin, Murthly and Abercairney in Perthshire.
