The Louisiana orange tree, also known as Naranjo de los Osages or Espino de los Osages, whose scientific name is Maclura Pomifera, is a typical tree in the southern United States where it is appreciated for its characteristic fruits and hard wood.
Originally, this species was only found in southern states like Oklahoma, Texas or Louisiana. However, during the past century, it was spreading to the north of the country. There it is known as Osage Orange. This name is due, on the one hand, to the American Indian tribe that populated the area, the Osage, and who used it to make bows and arrows. And, on the other hand, its fruit, similar to orange or grapefruit, although it is not edible by man.

Uses of naranjo de los osages wood
As for the uses of this wood, we find a strong contradiction. On the other hand, it is a shiny wood, which provides an exceptional finish and contrast, and can be used perfectly for quality joinery work. However, its hardness made its main uses work, those where what is sought is its resistance and not its appearance. For example electric poles, fences, cars, wooden wheels …
Other uses other than the Louisiana orange tree are obtaining yellow dyes using only hot water and as a species for reforestation in areas where erosion must be avoided.
