The Mulberry/Osage didn't have the thorns - They were on a different tree. A co-worker had given me a small piece of Osage to show me what it looked like but that was before I picked this stuff up. The color on that was incredibly yellow... Wish I had kept it for comparison. If it was Osage, I was going to put it aside for a few years and try it. Seems like the majority thinks it's Mulberry though.
