I had to look up what an Osage Oragne tree was, and I have seen them before but the likelihood of me coming across one to use is going to be rare. My guess would be that the common hardwood trees (pecan, oak and mesquite) would also be good to submerge as well because the wood is denser? While I don't have a lot of these on my property, they are very abundant in the neighborhoods around my house and are frequently taken down.
