HARROW DIAMOND
Prunus persica 'Harrow Diamond'
About the Variety: Harrow Diamond is a hardy freestone peach developed by Agriculture Canada's Harrow Research Station (same program that produced Harrow pear varieties). Released in 2003, it was bred specifically for cold hardiness and bacterial spot resistance. Harrow Diamond represents Canadian breeding focused on varieties that can handle harsh winters and unpredictable spring weather while maintaining excellent fruit quality.
​
Fruit Description: Medium to large freestone peaches with attractive red blush over yellow background. Flesh is yellow, firm, and very flavorful. Quality is excellent - sweet with good acid balance and rich peach flavor. Texture is smooth and juicy when properly ripened. The combination of cold tolerance and quality makes Harrow Diamond special.

How to Share This Fruit: Harrow Diamond's cold hardiness and disease resistance make it perfect for climate resilience education in mid-August. Organize "heritage and innovation" events discussing how Canadian breeding programs create varieties suited to challenging climates. The excellent quality despite hardy genetics provides opportunity to challenge assumptions that cold-hardy varieties sacrifice flavor. Perfect for mid-summer harvest celebrations when people are most engaged with fresh local food. Consider preservation workshops where the excellent canning quality shines. The bacterial spot resistance typically means clean, attractive fruit - great for outreach and promotional materials. Pair with Contender for comparative tastings of two different cold-hardy breeding programs (North Carolina vs. Canada). Use Harrow Diamond to discuss international fruit breeding collaboration - showing how programs in different countries share genetics and breeding goals. The reliable production makes it suitable for annual community traditions where consistency matters.
