The netelboom is its wide screen, the crown-shaped shade tree of choice. He is distinguished by its graceful overhanging branches in the Netherlands and Belgium as a park planted. He is quite hardy.

The celtisfamilie comprises about 75 genera.

Celtis australis


The word is celtis an ancient Greek name for a tree with sweet fruits from the Greek word celthis, a sort of sweet lotus fruit. Australis does not mean that the tree is native to Australia, but south. Occidentalis western means. He probably got its name because netelboom the leaves resemble those of other nettles (nettle, deaf nettle).

The name whips tree has to do with the fact that once the branches were made whips. The English name ‘Witches Broom’ is related to mushrooms and mosses often grow on the branches.

The Dakota Indians call this tree and that means Yammumnugapi crumble, because birds the seeds with their beaks chop.

The first French settlers called the netelboom ‘bois inconnu “(unknown wood).



Celtis australis is native to southern Europe to the Southern Alps, North Africa, West Africa, South Africa and the Levant. We find him as shade trees in big French cities like Nîmes, Toulouse and Paris.

The bark is smooth and gray, similar to those of beech, flaking in old age.


The pale yellow, elastic wood of the netelboom is valuable and is used for the manufacture of pallets, crates, farm equipment, sports equipment, veneer, musical instruments and turning. He also plays a role in making charcoal. The bark yields a yellow dye. The ground seeds are suitable for cakes to be processed.

The wood of the netelboom in America acted as ‘beaver wood’.
