If I wanted clones of the original tree I would break off a few twigs, getting a good bark heel, dip in hormone rooting powder, stick in a pot and let them get on with it. I would end up with clones of original.
From seed? Not a clone, could have been pollinated froma other tree.
Grafted? That means to "a root stock". What of? So not a clone.
Am I missing something here? They are claiming to be making clones from seed and using root stock.
