Osage orange from Argentina has good working properties and has a lesser tendency to crack than the American variety. Color also stays yellow/orange a lot longer than the American type. One of the few cases where the substitute is better than the original. As of spring 2011, it looks like osage orange prices will go up. They have been sold at some loss (no idea why) by the mill that produces them for years and they now hope to make a profit. Note: Soon after this announcement, the mill went broke. Most wood sold now is just the leftovers from that mill years ago.
