Whether you buy your blueberries in season at the supermarket or have the privilege of going to a “you-pick” stand, there’s no denying their refreshing, sweet flavor. Their popularity in America makes it clear that the U.S. is the world’s largest blueberry producer, but there’s one state amongst the 50 that you can thank in particular.

Washington state produces the most blueberries every year, harvesting an impressive 160 million pounds in 2019 alone. This is due in part to their blueberry season that lasts from June to October, which is longer than average thanks to Washington’s sustainable weather pattern.

Washington blueberries grow in the western part of the state but also in the east, where the soil is an ideal acidity, and the low precipitation breeds fewer pests. This provides them with a five-month harvest period where berries in the west are harvested later, while the ones in the east are harvested in June before temperatures cool down.
