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.
