Ствол тсуги канадской У молодых деревьев кора красноватая или тёмно-коричневая, чешуйчатая. С возрастом она становится толстой и глубоко бороздчатой с плоской вершиной, приобретая тёмный седовато-коричневый оттенок. Чешуйки коры отслаиваются. Если кору сломать, части разлома покрываются фиолетовыми крапинками[7]. Толщина коры взрослых деревьев составляет 1,3—2 см[5]. Шишки тсуги канадской Хвоя плоская, мелкая (0,5—1,5 см) притупленная на конце; сверху — тёмно-зелёная, с продольной бороздкой, снизу — светло-зелёная с двумя узкими полосками. Хвоинки заканчиваются небольшим черешком, который крепится к маленьким подушечкам, расположенным на веточках растения[7]. Шишки овальные, серовато-бурые, до 2,5 см длиной, растущие прямо из верхушек веточек[8], семена мелкие (1—2 мм), яйцевидные, с крыльями[9]. Мужские стробилы — маленькие, жёлтые, округлые; женские стробилы — светло-зелёные. Вдоль каждого нового побега более чем 6 см длиной имеются небольшие боковые ответвления без почечной чешуи в их основаниях. На более коротких побегах эти отростки могут включить только короткий стебель, несколько маленьких хвоинок и зеленовато-коричневую верхушечную почку. Такие побеги существенно увеличиваю

Encyclopedic overview

An eastern hemlock branch at the Kortright Centre for Conservation. Tsuga canadensis, also known as Canadian hemlock, eastern hemlock-spruce, or eastern hemlock, and in the French-speaking regions of Canada as pruche du Canada, is a coniferous tree native to eastern North America. It is the state tree of Pennsylvania. Eastern hemlocks are widespread throughout much of the Great Lakes region, the Appalachian Mountains, The Maritimes and the Northeastern United States. They have been introduced in the United Kingdom and mainland Europe, where they are used as ornamental trees.

Eastern hemlock populations in North America are threatened in much of their range by the spread of the invasive Hemlock woolly adelgid, which infests and eventually kills trees. Declines in population from hemlock wooly adelgid infestation have led to Tsuga canadensis being listed as Near Threatened on the IUCN Red List.
