What I am trying to say is that all Mulberries I have seen have much bigger leaves like 4-6" and thicker branches. I would not like to end up with some kind of dwarf that would grow to a couple of feet only and would not be a Morus Nigra

I don’t think M. nigra can be ruled out based on those two characteristics at such a young age. I have had many leaves that size on my black beauty. They do tend to be stiffer and more sandpaper-like in texture than other mulberry leaves though. Hopefully it ends up being what you wanted, good luck!

with a potential size of 15'h and 10'w. This is the perfect size for my needs

==>> trees never really stop growing.. at some magical height ...

and i would never expect a fast growing tree .. to stay that small ...though that might just be the name of the business ....

anyway.. live your dream.. but all kinds of warning flares are going off in my head about all the hype ... at worse.. you buy a tree saw ... and learn how to prune to maintain the size you want ....

ken

gotta wonder why there are so few pix of the actual tree .. hmmmm

Black Mulberry leaves --as my scan shows-- are roundish overall, heart-shaped at their bases, on short stalks. They are lobed rarely. They are dark and semi-glossy above, paler and fuzzy beneath. They measure mostly 3 to 5 inches, up to at most 9.
