If you mean Prunus padus when you say wild cherry, it should produce fruit all by itself - but it isn't very pleasant to eat. Its common name is Bird Cherry, because they're usually left on the tree for the birds rather than being picked and eaten.

Thank you, im not sure what type it is. The lady i bought it from uses the fruit in jams from the parent tree. Will the blossoms still be a beautiful as other cherry blossoms?

Google Prunus padus - the blossoms are quite different from ornamental flowering cherries, being white and sticking up like candles. Attractive though.

Prunus padus is used in jam, Canadian friends of our brought some over. As Bamboo says it will not look like the ornamental cherries when it flowers.
