Knowra Populus tremula Populus tremula Populus tremula, the European aspen, is a deciduous tree native to Europe and parts of Asia. Its laterally flattened leaf stalks make the leaves tremble in light winds.
Populus : Populus is a genus of deciduous trees that includes poplars, aspens, and cottonwoods. European aspen belongs to this genus of wind-pollinated trees.
Phyllode : A phyllode is a flattened leaf stalk that functions like a leaf blade, often replacing a reduced true blade. An aspen leaf has a distinct blade; its flattened stalk causes trembling instead.
Aspen wood : Aspen wood is the light-colored, relatively soft timber obtained from trees in the genus Populus. European aspen wood is used for products including pulp, panels, and matches.
Pando : Pando is a vast clonal colony of quaking aspen in Utah, United States. It is a famous North American example of clonal aspen growth, not Populus tremula.
Salicaceae : Salicaceae is a family of flowering plants that includes willows and poplars. The family places European aspen among its close relatives, the willows.
Vegetative reproduction : Vegetative reproduction produces new plants from stems, roots, leaves, or other non-seed tissues. Root suckers allow an aspen to multiply without producing seeds.
Plywood : Plywood is an engineered wood panel made by bonding thin veneers with their grain directions alternating. Aspen timber can be peeled into veneers for lightweight panels.
Aspen parkland : Aspen parkland is a transitional biome of prairie and boreal forest, characterized by groves of aspen and grassland. It illustrates how aspen woodland can form a shifting boundary with open grassland.
Leaf petiole : A leaf petiole is the stalk connecting a leaf blade to a plant stem. Its flattened petiole lets the leaf blade swing in passing air.
Root sucker : A root sucker is a shoot that grows from a plant's root and can develop into a separate stem. This is the shoot through which an aspen clone expands above ground.
