From glaciers to greeting cards, discover how the Maine wild blueberry became one of the state's most recognizable symbols and inspired our handcrafted paper art.
Living in Maine, it's impossible not to notice how deeply wild blueberries are woven into everyday life. They're our official state berry, one of our most important agricultural crops, and a celebrated symbol of summers in Maine.
So, how did a little berry become such a huge part of Maine's identity?
Let's find out.
Meet the Maine Wild Blueberry
The Maine wild blueberry is unlike any other blueberry in the world. Wild, resilient, and bursting with sweet-tart flavor, it's one of nature's most remarkable fruits.
Naturally Wild
Maine's wild blueberries are considered wild because they've never been planted or domesticated. Unlike cultivated highbush blueberries, they continue to spread naturally across Maine's barrens, just as they have for thousands of years.
Small and Mighty
Wild blueberries are about half the size of cultivated blueberries, but don't let their size fool you. They pack a concentrated sweet-tart flavor and an impressive nutritional profile. They're a good source of fiber and vitamin C, and they're especially well known for their high levels of naturally occurring antioxidants.
Wild blueberries have been the subject of scientific research for decades because of their unique nutritional profile. Studies continue to explore how their naturally occurring antioxidants and other plant compounds may support brain health, heart health, and healthy aging. Combined with their exceptional flavor, they've earned a reputation as one of nature's original superfoods.
Growing Against the Odds
About 20,000 years ago, much of what is now Maine was covered by glaciers. As the climate warmed and the glaciers slowly melted, they scraped away much of the existing topsoil. What remained was thin, rocky, acidic soil that held relatively few nutrients.
For most plants, it was a difficult place to grow. Their roots struggled to find enough nutrients, and the short growing season and long, cold winters made survival even harder.
Wild blueberries were among the few plants that didn't just survive these conditions. They thrived in them.
We don't know exactly when the first wild blueberries became established after the glaciers retreated. That part of the story is older than written history. What we do know is that once the berries arrived, they found an environment perfectly suited to them.
The Hidden Life of a Wild Blueberry
Most of the wild blueberry plant lives where we never see it. What appears to be a small, delicate shrub is really the visible tip of an extensive underground network.
Beneath the surface, underground stems called rhizomes slowly spread through the soil. They store energy through Maine's long winters before sending up fresh shoots each spring.
Blueberry Fun Fact Wild blueberry plants have a secret underground sidekick: tiny fungi. They latch onto the blueberry plant's roots and help absorb nutrients from Maine's stubborn, nutrient-poor soils. In return, the blueberry plant shares some of the sugars it produces through photosynthesis. It's one of nature's sweetest partnerships.
Year after year, the rhizomes continue to spread beneath the soil, slowly expanding each colony of wild blueberries. Over thousands of years, this underground network has helped the plants spread naturally across parts of Maine.
The Maine Blueberry Barrens
Despite the name, a blueberry barren isn't barren at all. The term refers to land that is too poor to support most traditional crops, not because it's devoid of vegetation.
A blueberry barren is a naturally occurring landscape where wild blueberries grow in dense, low carpets across open ground. These broad fields are found primarily in Downeast Maine, where the thin, acidic soils and cool climate create ideal growing conditions for wild blueberries.
Some blueberry barrens cover hundreds or even thousands of acres, creating one of the largest naturally occurring wild blueberry landscapes in the world. During much of the year, the barrens appear green. In spring they're covered with delicate white blossoms, and by midsummer they're filled with tiny blue berries.
In autumn, however, the plants turn brilliant shades of crimson and scarlet, transforming entire hillsides into a sea of red.
Like many deciduous plants, wild blueberry leaves stop producing chlorophyll as the days grow shorter. As the green fades, the leaves turn brilliant shades of crimson and scarlet, creating one of Maine's most spectacular fall landscapes.
Living with the Land
The First Blueberry Stewards
The first human stewards of Maine's wild blueberry barrens were the Indigenous peoples of what is now Maine. Today, they are known collectively as the Wabanaki Confederacy, whose name means People of the Dawnland.
For thousands of years, Wabanaki families harvested wild blueberries each summer for food, medicine, and traditional crafts. The berries were an important seasonal resource, and the annual harvest brought families together to share knowledge, strengthen community, and pass traditions from one generation to the next.
Their relationship with the land was rooted in respect and stewardship. Through generations of observation, they learned how to care for the barrens in ways that encouraged healthy blueberry growth. Periodic, low-intensity burning kept the barrens open, reduced competing shrubs and trees, returned nutrients to the soil, and encouraged new growth.
European Settlement
As European settlers established communities across Maine during the 1600s and 1700s, many settled along the Downeast coast, where vast wild blueberry barrens stretched across the landscape. The barrens had been cared for by Indigenous peoples for generations, and settlers quickly recognized the berries as an abundant source of food.
Over time, summer trips to the blueberry barrens became part of everyday life. Families headed into the barrens each summer to gather berries for fresh eating, drying, and preserving, selling any surplus in nearby communities. In many areas, the harvest remained open to anyone willing to do the work.
Settlers also adopted many of the stewardship practices used by the Wabanaki. Periodic burning helped keep competing shrubs and trees in check while encouraging healthy blueberry growth.
For nearly two centuries, wild blueberries remained a seasonal food gathered from naturally growing barrens. Most of the harvest stayed close to home, enjoyed fresh, dried, or preserved for the winter months.
From Barrens to Battlefields
In 1861, the American Civil War changed the future of Maine's wild blueberries.
At the time, several canneries along Maine's coast were preserving sardines and other seafood for customers across the country. The South was one of their largest markets, but when the Southern states seceded from the Union, that business disappeared almost overnight.
Maine's coastal canneries suddenly found themselves with equipment, skilled workers, and far fewer customers. At the very same time, the Union Army needed enormous quantities of food that could be preserved, transported long distances, and stored for months at a time.
Wild blueberries proved to be an unexpected solution. Every summer, millions of berries ripened naturally across the barrens of Downeast Maine, and they could be canned using the same equipment already found in Maine's processing plants.
For many Union soldiers not from New England, canned wild blueberries were their first introduction to the fruit. Their sweet-tart flavor offered a welcome change from the army's monotonous diet and a rare taste of summer in the middle of war.
By the time the war ended in 1865, thousands of Union soldiers had discovered Maine's wild blueberries. Many returned home with an appreciation for the berries, helping create a demand that stretched far beyond New England.
What Built Maine's Wild Blueberry Industry
Maine's wild blueberries were abundant, but abundance alone doesn't build an industry. Three innovations transformed this seasonal harvest into a product that could be enjoyed all year across the country: the invention of the blueberry rake, the growth of commercial processors like Wyman's, and the development of flash freezing.
The Hand Rake (late 1800s)
Before the invention of the blueberry rake, berries were picked entirely by hand, making large harvests slow and labor intensive. The hand rake allowed workers to gather ripe berries far more efficiently without uprooting the plants. It quickly became an essential tool of Maine's blueberry harvest and remains in use today.
Jasper Wyman and Commercial Processing (1874)
Founded in 1874 by Jasper Wyman in Milbridge, Maine, Wyman's began as a seafood cannery. As demand for wild blueberries continued to grow after the Civil War, Wyman recognized the fruit's commercial potential. Facing increasing competition in seafood canning, the company gradually expanded into blueberry processing and, by 1900, had shifted its primary focus to wild blueberries.
Wyman's helped transform Maine's wild blueberries from a seasonal local harvest into a nationally distributed product. Today, the company remains family owned and is one of the world's leading processors of frozen wild blueberries.
Flash Freezing (Mid-1900s)
Canning introduced Maine wild blueberries to the country, but flash freezing transformed the industry. Freezing the berries shortly after harvest preserved their flavor, texture, color, and nutritional value without relying on sugar or syrup. Instead of being available only during harvest season, Maine wild blueberries could now be enjoyed year-round almost anywhere.
The Modern Maine Wild Blueberry
Thousands of years after the first wild blueberries took root in Maine's rocky soils, they continue to shape the state's landscape, economy, and way of life.
A Big Industry
Today, Maine is the world's largest producer of wild blueberries, supplying nearly 40% of the world's wild blueberry harvest and almost all of the wild blueberries grown commercially in the United States.
The Maine wild blueberry industry contributes hundreds of millions of dollars to the state's economy and supports thousands of jobs. More than 500 growers steward approximately 46,000 acres of wild blueberry barrens, producing around 90 million pounds of berries in a typical season.
Each summer, berries harvested from the same naturally occurring barrens that have supported wild blueberries for thousands of years are shipped to consumers around the world.
Stewardship Today
Despite its size, the Maine wild blueberry industry still depends on healthy blueberry barrens. Wild blueberries grow naturally, but productive barrens require thoughtful stewardship.
Today's growers build on generations of knowledge, combining traditional practices with modern agricultural research to care for the barrens. Their work supports not only healthy blueberry plants, but also pollinators, wildlife, and the broader ecosystem.
The infographic below highlights several of the practices used today to steward Maine's wild blueberry barrens.
A Cause for Celebration
For many Mainers, the arrival of wild blueberry season is more than the beginning of harvest. It's a celebration of the people, places, and traditions that have shaped life in Maine for generations.
Across the state, blueberry season brings festivals, farm tours, roadside stands, and opportunities to pick berries straight from the barrens. Events celebrate the harvest and bring together growers, local businesses, residents, and visitors to enjoy one of Maine's most beloved agricultural traditions.
Events like the Machias Wild Blueberry Festival, the Union Fair & Maine Wild Blueberry Festival, and Wild Blueberry Weekend bring together growers, local businesses, residents, and visitors to celebrate the little berry that has become one of Maine's biggest icons.
Berry Tasty
Wild blueberries may be small, but they deliver big flavor. Their naturally concentrated sweet-tart taste makes them a favorite ingredient in everything from breakfast to dessert. Every summer, fresh Maine wild blueberries find their way into pies, muffins, pancakes, cobblers, crisps, jams, ice cream, salads, and countless family recipes.
Whether enjoyed fresh from the barrens or tucked into a favorite dish, they're one of the most delicious traditions of a Maine summer.
A Symbol of Home
The wild blueberry is one of Maine's most recognizable symbols. It appears in paintings, pottery, quilts, ornaments, postcards, souvenirs, and countless other works celebrating the state. Alongside the lobster, lighthouse, chickadee, and eastern white pine, it has become an enduring icon of Maine.
In 1991, the wild blueberry was officially designated Maine's state berry, honoring a fruit that had long been woven into Maine's landscape, traditions, and way of life.
More than a fruit, the wild blueberry tells an important part of Maine's story. It carries the story of a plant shaped by glaciers, generations of stewardship, remarkable ingenuity, and traditions that continue to bring people together each season. For many, it's also a sweet reminder of summer.
