Romance Series Sour Cherry Seeds
Romance Series Sour Cherry Seeds
Pack contains: 15+ seeds
These Sour Cherry seeds come from a mix of Juliet, Valentine, Cupid, Romeo, and Crimson Passion fruit. The seedlings will be genetically varied rather than copies of the named Romance Series cultivars, but some may produce similar large, richly flavoured sour cherries.
The Romance Series cherries are Prunus × kerrasis hybrids with about 75 percent Prunus cerasus and 25 percent Prunus fruticosa ancestry, named for the breeding work of Dr. Les Kerr. Their fruit is more tart than common sweet cherries but can also develop high sugar when fully ripe.
Cold Hardiness Zone: 3
Seed Source: Manitoba
Stratification Required: 1 month warm, followed by 3 to 5 months cold

More about this plant
University of Saskatchewan dwarf sour cherries combine sour-cherry and selected Mongolian-cherry material. Their named cultivars are self-compatible and ripen from early through mid-to-late August in Saskatchewan. The named parents range from few to some suckers, with Crimson Passion listed as producing very few. Those are parent references only: seedlings from this mixed lot can differ, and the packet did not resolve a supported fruit-mass value.
