Description Harglow apricot is considered one of the most reliable apricot varieties for cold-winter and frost-prone regions. Developed in Canada as part of the Har-series breeding program, it was selected specifically for exceptional flower bud hardiness and a notably late bloom—two traits that dramatically improve apricot success where spring frosts are common. The fruit is medium to large, bright orange with a mild blush and classic apricot flavor that balances sweetness with gentle acidity. While Harglow is not the earliest apricot to ripen, its delayed bloom timing greatly increases the likelihood of a full crop in challenging climates, making it a favorite among growers who have struggled with apricots in the past. Overview Late-blooming apricot with outstanding frost resistance. Medium-large fruit with classic apricot flavor. Developed for cold and variable spring climates. Reliable producer compared to many apricot varieties. Self-fertile. Growing Details Latin Name: Prunus armeniaca ’Harglow’Site and Soil: 1/2 day to full day of sun; well-drained soil essentialRootstock: Marianna 2624Hardiness: USDA Zones 5–8Bearing Age: 1–3 yearsSize at Maturity: Typically 12–15 ft tall and wide (maintained smaller with pruning)Bloom Time: Late spring (later than most apricots)Ripening Time: Mid-summerPollination Requirements: Self-fertilePests & Diseases: Improved resistance compared to many apricots; good airflow and drainage reduce issues Additional Notes Grower’s Insight: Harglow is often considered one of the safest apricot choices for frost-prone sites due to its exceptionally late bloom. Regional Insight: Harglow excels in the Pacific Northwest, Upper Midwest, and northern growing regions where spring frosts routinely challenge apricot production. Later bloom timing makes site selection especially important—avoid warm microclimates that encourage early growth. Best suited for fresh eating and preserves where reliability matters more than earliest harvest. Explore more apricot varieties in our collection: Apricot Trees
