Don't sweat it. It's mulberry. I just found out about them this year and went on a quest to several nurseries to find one and I did. I became very familiar with them. From what I've read, several members here have huge trees.
me too recently know of the benefits from a shrimp forum, apparently the leaves can be fed to crystals red shrimps too , i just bought some cuttings from a confirmed white mulberry , but no roots , have to wait for a week or two , lol not much confidence as this is mine first time trying a cutting
