your hubby's first-hand accounts of weather conditions and true nigras being gnarly are promising indicators!
could also be that those bloggers received albas, and were too disappointed to even follow up on their respective blogs. Even in this forum, you'd see many members complaining about mulberries, saying mulbs are nothing more than weedy pests, and i can't blame them, since evidently they've never tasted a true black mulberry, and if they have actually bought one, they probably received impostors, which grew fast and became weedy pests which produced lackluster fruits(whereas nigras grow really slow, and produce superb fruits)..
thus the tendency to denigrate mulbs for not being nigras.
needless to say, your blog is the first one have come across where the specimen is authentic nigra. And surely, the provenance which spanned two growing seasons, of finally getting the real mccoy after receiving a faux nigra was just as eventful as getting the real mccoy to fruit! Has been a bit of a journey, no doubt.. Burntridge did you good by sending an old specimen, so despite the delay with the faux nigra you received last year, your overall waiting time was less than what others generally have to endure, myself included
