norjanvaahtera

Norjanvaahtera is the Finnish name for Acer platanoides, commonly known as the Norway maple. It is a species of deciduous tree in the soapberry family, Sapindaceae. Native to eastern and central Europe and southwestern Asia, it has been widely introduced as a popular ornamental and shade tree in many other temperate regions, including North America.

The Norway maple is characterized by its large size, typically reaching heights of 20-30 meters (65-100 feet) with a trunk diameter of up to 1.5 meters (5 feet). It has a dense, rounded crown and produces abundant seeds called samaras. The leaves are palmate, typically with five lobes, and are a distinctive bright green, turning vibrant yellow, orange, or red in the autumn. Its bark is dark gray and furrowed in mature trees.

While valued for its ornamental qualities and shade provision, the Norway maple is also considered an invasive species in some areas outside its native range, particularly in North America. Its aggressive growth habit, ability to outcompete native vegetation, and prolific seed production can lead to ecological imbalances. Control and management efforts are sometimes implemented in areas where it poses an invasive threat. In its native habitat, it plays a role in forest ecosystems.
