Description
Candy Heart Pluerry™ is a Zaiger-bred interspecific selected for very sweet fruit and an unusually forgiving harvest window. Rather than demanding a narrow pick date, the fruit continues to improve as it hangs, allowing sugars and flavor to deepen well into late summer.
The fruit develops dark red skin with yellow to amber flesh and a rich, sweet flavor that leans low-acid. When allowed proper hang time, Candy Heart delivers a satisfying fresh-eating experience that feels distinctly “late-season”—dense, sweet, and rewarding after earlier hybrids have finished.
Candy Heart ripens mid-to-late within pluerry types and is often harvested about a month after very early pluerries like Sugar Twist, depending on region. In warm-summer climates this commonly places harvest in late July through August, while cooler regions may see ripening shift later. Cross-pollination is recommended for consistent production.

Additional Notes
- Grower’s Insight: Candy Heart benefits from patience. Allowing fruit to hang longer than average is key to reaching its best sweetness and depth of flavor.
- Regional Insight: In cool or wet spring climates such as the Pacific Northwest, coastal regions, or higher elevations, early bloom can limit pollinator activity. Plant multiple compatible varieties nearby and support early-season pollinators to improve fruit set.
- Ripening Context: Compared within pluerry types, Candy Heart typically ripens later than very early selections like Sugar Twist, extending the interspecific harvest window into late summer.
- Thin fruit in heavy-set years to improve size, sweetness consistency, and branch health.
