I'd agree they aren't beefsteaks and it sure ins't Sorrento. But it also could have been just that one mis-packaged seed rather than the whole packet. Stray seeds in packets happen.

If you grew out several of them and they are all the same then you need to contact the seller.

That particular vendor isn't a source for any of us as it is located in Bangalore, India. So their reputation is an unknown. If they are unwilling to address the issue consider it a lesson learned and find a different supplier.

All plants turned out to produce same plums. We don't use much of cherrys around here in India, salad isn't our regular food habit.

Time to give away a lot of cherrys!
