Argentine Osage: Brilliant Color, Extreme Durability, and Outstanding Turning Wood

Argentine Osage, commonly associated with Maclura tinctoria (often referred to as Fustic or Old Fustic), is a dense tropical hardwood native to Central and South America. It is closely related to the North American Osage Orange (Maclura pomifera) and shares many of the same desirable characteristics—most notably its brilliant yellow coloration and exceptional durability.

For woodturners, Argentine Osage offers bold natural color, impressive strength, and excellent finishing qualities, making it a unique and rewarding material to work with.
