your babies have the characteristics of true nigras @pileta and @Drew51 . And if some of those turn out to be male, and please forgive me if it sounds like ill will, that i actually wish that some will be. Reason being is that nurseries/importers never really bothered obtaining budwood from male nigras for the usa market, so virtually all nigras in america are female. And this equates to zero genetic diversity since there will never be cross pollination, unless there’s that very unlikely chance of a bud sport developing on someones female nigra tree and the sport actually has radically different characteristics from the mother plant.
on the other hand, having males around may also spell trouble, or at the least, be a hassle. What i mean is that all my nigra trees are ‘virgins’ ( there aren’t any males to fertilize and produce viable seed), which perhaps explains why all the berries they produce are conveniently seedless. If someone should start a nigra cross-breeding experiment in our neighborhood by raising male and female nigras, that someone could perhaps transform our seedless berries into seeded ones.
and if this should happen to a litigious party, it could result in a most novel agricultural lawsuit
