i bought a dwarf black beauty and dwarf perisan mulberry. the persian fruit should be slightly bigger and taste better but they are exactly the same. Ripening fruit size flavor. i can only think mislabel from nursery.
Nigra fruits are very similar.
Where did you get them? Do the leaves and other details look the same also?
i bought them at the same local nursery! same time leaves look the same to me.
I cannot distinguish between the leaves or fruits of the different Nigra strains that I’ve seen (Persian, King James, Black Beauty). Some are lobed but that’s about it.
i think its just the same variety but somehow the name was changed. i hate when that happens adds to the confusion. when its just one variety. just like figs sadly, serious collectors just have to try test and find out.
