The Weeping Canadian hemlock (Tsuga canadensis ‘Sargentii’) is a cultivar of the Eastern hemlock (Tsuga canadensis). It features numerous pendulous branches and is most effectively employed near water, in rock gardens or on embankments. The tree is usually trained to grow several feet tall and then allowed to spread up to two times its height. The needles are dark green and alternate arranged. The Eastern hemlock is native to America. The weeping (pendula) cultivar was first introduced in horticulture in a supplement of A.J. Downing’s 1859 edition Treatise on the Theory and Practice of Landscape gardening byMrs. Henry Winthrop Sargent and carries his name. Today it is threatened by the woolly adelgid. The common name “hemlock” comes from the Indians of upper New York who called this tree “Ohnehtah” and referred to Canada as the land of the “Ohnehtah”. Notably the poisonous hemlocks are not pinaceae but come from the parsley family (Apiaceae), Circuta maculata and Conium maculatum).Tsuga is the Japanese name for trees in this genus. The specific epithet means native of Canada.
