UK’s first homegrown blueberry developed

The James Hutton Institute has announced the successful development of the UK’s first domestically bred blueberry, “Highland Charm,” created at its Invergowrie research facility in Scotland. The result of a decade of work, this cultivar was selected from over 300 unique crosses of the native North American species Vaccinium corymbosum, carefully bred to thrive in the Scottish climate.

Blueberry breeder Susan McCallum described the new variety as “a real standout,” highlighting its high yields, large fruit size, balanced sugar-acid profile, excellent flavour, and long shelf life. “It has proven consistent in yield, size, and taste across multiple trial seasons. Growers are really excited about it,” she said.

The berry has already performed well in UK and EU trials across diverse environmental conditions. Research is now expanding to assess Highland Charm’s performance under reduced input systems, supporting the industry’s goals for sustainability and efficiency. Scotland’s unique growing conditions—cool summers, fertile soil, and clean water—contribute to the berry’s intense, well-balanced flavour compared to those ripened quickly in hotter climates.

The James Hutton Institute’s soft fruit breeding programme supports the entire supply chain, from growers to retailers, using marker-assisted breeding to accelerate development. The programme also addresses broader challenges such as climate resilience, pest and disease control with reduced pesticide use, and rising production costs. With UK consumers importing 90% of the 60,000 tons of blueberries consumed annually, Highland Charm offers potential for expansion of local supply. The variety is currently undergoing licensing and is expected to appear in supermarkets within two to three years, alongside a sister variety now in development.
