The graceful western hemlock - Tsuga heterophylla in Latin - was introduced into Scotland during the 19th century for ornamental purposes. It has also been used commercially on a limited scale. Its tolerance to light shade allowed it to be planted under old broadleaved woodlands, but its susceptibility to butt rot has greatly reduced this practice.
