Plum!

I bought this tree and planted it 4 years ago. It hasn't done any growing since, but this year at least it has decided to flower. It is supposed to be a Victoria plum but I planted one of those in the past and it romped ahead, so I have my doubts! If we could have one fruit setting, we will have the answer! Fingers crossed. My apricot from the same source turned out to be a nectarine and the eating cherry  is a wild cherry so you never know...
