Tsuga canadensis 'Gentsch White' is a low-maintenance dwarf that selection of Canadian hemlock that grows well in medium to full shade, although it can handle full sun in northern latitudes. Like all hemlocks, which are under-story trees, this conifer should not be allowed to dry out during prolonged heat spells. The heat, combined with full sun, will scorch the white new growth for which it is prized. Annual shearing is advised to maintain a compact habit and to promote the white new growth." After 10 years of growth, a mature specimen will measure 4.5 feet (1.5 m) tall and wide, an annual growth rate of 4 to 6 inches (10 - 15 cm).
