Ran in to this plant a the supermarket. It was only 3 bucks so I picked it up out of curiosity. I've started growing mulberry trees a while a go and did quite some youtubing and reading about them. Never have I seen or read about a climbing black mulberry. Google gives me 0 hits when searching for one. The picture on the label is definitely a mulberry, the plant in this stage look more like a blackberry to me.
Question: does this exist? can you train them as climbers (what would happen to the trunk size???), or is this a fake?
