I would think so. Many plums are good for Zone 4. The biggest concern I have is even though where I am is zone 5, we are actually zone 4 due to our micro climate. A couple of my other plums blossom too quickly in the Spring (one is good for Zone 5) and there are too few insects to pollinate. The one I pictured is good for zone 4, and was called a Russian Plum. Each year I get more and more fruit. Wish I could find another to plant.
