Osage Orange is a strong, flexible, and durable wood popular among Osage, Comanche, and other Native Americans for making bows.
"In Arkansas, in the early 19th century, a good Osage bow was worth a horse and a blanket," reported Harriet Keeler in her classic 1900 book, Our Native Trees and How to Identify Them.
Osage Orange is a favorite wood of Grammy Award-winning Carolina Chocolate Drops founding member, Dom Flemons.
Only very distantly related to the orange, Osage Orange is instead a member of the mulberry family. Palmer and Fowler's Fieldbook of Natural History 2nd edition, rates Osage orange wood as being at least twice as hard and strong as white oak. The dried wood has the highest BTU content of any commonly available North American wood, and burns long and hot (but you might not want to brag about this to your melody band mates).
