The maple genus (Acer) comprises about 110 to 200 species and is distributed over large parts of Europe and North America. The sycamore maple (Acer pseudoplatanus) is one of the most valuable deciduous trees. The curly maple, also called curly maple, is particularly decorative and valuable.

Sycamore maple is widespread throughout Central Europe and also occurs in Turkey, the Caucasus, the Mediterranean region and Great Britain. Acer pseudoplatanus does not occur in pure stands but only in association with other hardwood species.
Trunk and bark
Maple can reach a height of up to 30 m and a diameter of up to 1.0 m. It is usually found from 40 years onwards. Maple is usually used from a diameter of 40 cm, as disturbing discolouration occurs with increasing diameter. The bark is grey, long and smooth with thin flaking scales when old.
Characteristics and wood colour
The annual rings of maple are visible as fine lines through the darker late wood. The vessels are not visible and the frequent, fine medullary rays form bright shiny lines on the brain cut. The maple wood is yellowish-white, glossy and without heartwood colouring, i.e. the sapwood and heartwood do not stand out from each other but are the same colour.
