Mulberry species identification

@MisterGuy

Could you please possibly keep posting as it leafs out, and possibly, for no particular reason, point out how to tell it’s a black beauty?

I will keep posting progress on all my plants for years to come

For this plant, pictures will help you discern that it is Morris nigra. To discern whether it is the Black Beauty cultivar though, is a matter of tasting and biological tests.
