- As the name suggests, Sweetheart is a large, bright red heart-shaped cherry. Sweetheart matures
at the end of the season in late July and remains firm after picking. This self-fertile cross of Van
and Newstar is productive with good firmness, size and flavor. The tree is spreading and
precocious, yielding heavy crops that may require some fruit thinning in optimal conditions.
Good as a pollinizer for other sweet cherries.
