Sour Cherry Seedlings were grown from open pollinated fruit collected in Manitoba from Juliet, Valentine, Cupid, Romeo, and Crimson Passion cherries in the University of Saskatchewan Romance series. These are seedlings, not named cultivars, so fruit and growth will vary while retaining traits from their sour cherry parents.
Romance cherries combine Prunus cerasus and Prunus fruticosa ancestry, and the name Prunus × kerrasis recognizes Dr. Les Kerr's breeding work. Their dark red fruit is about 1/2 to 3/4 inch across and is smaller and more tart than supermarket sweet cherries, but can develop high sugar and excellent flavour when fully ripe.

More about this plant
These are open-pollinated sour cherry seedlings, so they should be expected to vary rather than reproduce a named Romance-series cultivar. The named seed parents differ materially in mature height, suckering, fruit mass and August harvest timing; those parent measurements are not transferred to individual seedlings. Seed-parent guidance recommends full sun and well-drained loam or sandy loam. Clay can be tolerated where drainage remains good.
