Well, I did a dumb-dumb. I received a couple plants of black Munger raspberries and a couple Royalty purple raspberries. Unlabeled. And while I thought I had kept them sorted, I accidentally mixed them. They are too young to flower or fruit, so I have no idea who is who. I'm just looking at leaves and stems trying to discern a difference. And kicking myself.
Are there some leaf or stem characteristics that might help me re-sort? If you have any clues or tips (other than label the damn things), then I'm much obliged.
