When I first bought my house, about 5 years ago, I planted what was supposed to be a nectarine tree. It was grafted onto the root of a different tree--no idea what. Long story short, the nectarine graft died but the root stock it was grafted onto thrived. Last year, it had a few fuzzy fruits that I thought were just inedible peaches. This year, it's covered in those fruits. And someone suggested they might actually be almonds. From web searches, it's impossible to determine what this might be, so I thought that, perhaps, you could help in determining which it is. Thanks in advance.
