Populus tremula aka Poplar

Populus tremula, commonly known as aspen, common aspen, Eurasian aspen, European aspen, or quaking aspen, is a tall and vigorous deciduous tree native to cool temperate regions of Europe and Asia. It can be found in various countries such as Iceland, the British Isles, Kamchatka, Scandinavia, northern Russia, central Spain, Turkey, the Tian Shan, North Korea, and northern Japan. It even occurs at one site in northwest Africa in Algeria. In the southern part of its range, it thrives at high altitudes in mountains. This substantial tree can grow up to 40 meters tall and has a broad trunk that can reach over 1 meter in diameter. The bark is initially pale greenish-grey and smooth on young trees, but it becomes dark grey and fissured as the tree ages. The leaves, which are produced on mature branches, are nearly round and slightly wider than long. They have a coarsely toothed margin and a laterally flattened petiole, allowing them to tremble even in gentle breezes. This unique characteristic gives the tree its scientific name and one of its vernacular names, "langues de femmes." However, the leaves on seedlings and fast-growing stems of suckers have a different shape, being heart-shaped to nearly triangular and often larger in size. Overall, Populus tremula is a striking tree with rustling leaves that display vibrant autumn colors. It is well-adapted to its native habitats in Europe and Asia and can thrive in various climatic conditions.
