i know it is just a picture, but got to hand it to you—i have NEVER seen anything like it. It is beautiful!
have seen one in some Greek webpage depicting an 800 year old tree, but it had a much smaller canopy, presumably damaged by lightning or windy weather when the pic was taken(the longer a tree lives, the chances of it getting hit by a ‘big one’ increases…)
if you compare the branches, even the main trunk, of my fruiting ~10 year old ‘spring chickens’ to those with smaller caliper branches of your tree, mine are too smooth, coddled and pampered i feel they need to be shipped to mulberry boot camp for several decades more.
you are not the first person to say that, and i too, am beginning to have my doubts about the fancy schmancy names as noir, black beauty, etc.
i have successfully grafted nigras to albas, but they take forever to grow decided to buy the biggest, hence oldest specimens could get my hands on. Have never been lucky with marcots though, but not that it should matter, considering the laggard growth
btw, fruits are rarely available even in farmers markets here, and on the few occasions that they are, nigra berries are sold for 20$/lb.
again, thanks for posting, and feel free to post more!
