Description
Razz was bred in 1934 by Frederick Coville, the man who domesticated the blueberry in the first place. It then sat as a numbered USDA selection for about seventy-five years, because the berries were too soft to survive commercial shipping, and it was finally named and released in 2011.
What kept it in the collection that long is the flavor: a clear raspberry note running through a sweet, medium-sized, light blue blueberry. The softness that disqualified it from a truck is irrelevant in a garden, where the fruit travels from the bush to the bowl. The plant is vigorous and productive at about 5 to 6 ft and ripens midseason.

Additional Notes
- Grower’s Insight: Eat these within a day or two of picking. The softness that kept it out of the trade for seventy-five years is exactly what makes the flavor.
- Regional Insight: Blueberries crop best where winters are cold enough to meet their chill and the soil is naturally acid, which covers most of the country once the planting hole is prepared properly.
