Argentine Osage Orange (Maclura tinctoria), also called Fustic or Mora, is a South American relative of the domestic Osage Orange, with the same bright yellow-orange color. It grows from Mexico to Argentina, and was once a major source of yellow dye.It usually comes in larger sizes, with cleaner lumber and fewer defects than the US species. Like its cousin, its color deepens over time toward a richer golden brown, and a finish with UV protection slows the change. The grain is straight to interlocked with a medium texture.It's hard and dense, so it's tough on tools, but it turns and finishes well, polishing to a lovely luster. Sharp tools and light passes give the cleanest results. It's naturally durable, sharing much of its cousin's resistance to rot.It's a great choice for boxes, inlay, carving, cabinetry, crafts, bows, turnings and specialty pieces where you want a splash of color, and its larger, cleaner boards make it easier to use than the domestic species.
