Canadian hemlock also known as Eastern Hemlock is a needled evergreen with short soft needles. A mature tree can exceed forty feet in height although they can be pruned as a hedge. As with most conifers, well-drained soil is essential. Hemlocks will grow in acidic or alkaline soil, but drought can be fatal if they are not watered well in dry times.
They are one of the most shade tolerant evergreens; light shade is preferred. A sheltered location is helpful as hemlocks do not tolerate windy locations well; nor do they tolerate pollution well. No part of the tree is poisonous; hemlock poison is from unrelated plants in another genus.
