Blueberry Varieties

There are many different cultivars and varieties of blueberry. Here is an overview of the most common types of blueberries:

Highbush

This is the most widely commercially grown species. It is adaptable to different climates.
Varieties include Bluecrop, Duke, Spartan, Berkeley, and Patriot.
Highbush blueberries can grow up to 12 feet tall and are the largest type of blueberry.

Lowbush

Also called “wild blueberries”, lowbush are found growing wild in northeastern and eastern Canada as well as Maine.
Lowbush berries are small and intensely flavorful. They have a higher antioxidant content compared to other blueberry varieties.
Major commercial lowbush areas are found in Atlantic Canada and Quebec.

Rabbiteye

This variety thrives in hot humid climates like the southeastern United States.
Popular rabbiteye varieties include Premier, Tifblue, and Powderblue.
Rabbiteye bushes grow up to 6 feet tall and produce soft, juicy berries.

Southern Highbush

Southern highbush are a cross between northern highbush and rabbiteye varieties.
They are adaptable to warmer southern climates with mild winters.
Common southern high bush varieties are Legacy, Rebel, Ochlockonee, and Star.

Half-high bush

Half-high blueberries are hybrids bred to combine dwarf size with highbush qualities.
The compact 2-4 feet bushes are easy to harvest and maintain.
Popular varieties are Northblue and Northland.

So in summary, blueberry varieties can differ widely in size, texture, taste, hardiness, and growing range. But they all share the signature blueberry flavor and nutritional benefits.

Nutrition and Storage Tips

To get the most from your blueberries nutrition-wise, follow these picking, storage and prep tips:

Select plump firm berries – Choose berries that are firm, plump, have smooth skin, and are free of moisture or green/red coloring. Avoid mushy or moldy berries.
Refrigerate promptly – Get fresh berries into the fridge within 2 hours of picking or purchasing. Proper refrigeration extends shelf life.
Wash just before eating – Only rinse berries right before eating as washing too soon can cause mold growth.
Enjoy fresh or frozen – For maximum nutrition, enjoy berries fresh or individually quick freeze them.
Avoid soaking – Don’t soak blueberries as this diminishes the water-soluble vitamin content.
Use within 3 weeks – Eat fresh berries within 3 weeks. The nutrient content declines with long term storage as sugars convert to starch.
Freeze for later – To extend shelf life up to 1 year, individually quick freeze berries on a sheet pan then transfer to an airtight freezer bag.
Avoid high heat – When cooking blueberries, use a gentle hand. High heat can degrade their delicate nutrients.

Following these simple tips will help you select, store, and use blueberries to harness their maximum nutritional advantages. Take advantage of blueberries’ short growing season by freezing or preserving some for enjoyment all year round.

Fascinating Blueberry Growing Facts

Blueberry cultivation requires precise conditions and expert growers. Here are some eye-opening facts about the complex process of growing these treasured berries:

Two crop cycles – Most blueberry varieties produce two separate crops. First-crop berries are smaller and less sweet. The larger, juicier second crop berries usually ripen 5-6 weeks later.
7-10 year harvest – After planting, it takes 2-3 years for blueberry shrubs to begin fruit production. Peak production occurs between years 7-10. Bushes can continue fruiting for 40+ years.
Precise soil needs – Blueberries require acidic soil with a pH between 4.2-4.8. Otherwise, they cannot absorb nutrients properly. Most soils require sulfur treatment to reach optimal acidity.
Extensive pruning – Detailed pruning is done each year to stimulate new growth, allow light penetration, and maximize yields. About 20% of ‘canes’ are removed post-harvest.
Bees are key – Bees play a critical role in blueberry pollination. Hives are set near blueberry fields during flowering season. Growers can bring in thousands of hives to ensure pollination.
Susceptible to climate extremes – Too much heat, cold, rain, or wind at key points in the growing process can devastate a crop. Frost protection is vital for blueberries.
Ripening challenges – Since individual berries ripen at different times, harvesting is very labor intensive. Multiple rounds of picking are required to ensure only ripe berries are collected.
Vulnerable to pests – Blueberries are prone to bird and animal pests who love to eat the ripe berries. Netting, sound cannons, and falconry help fend off intruders.

As you can see, growing plump, sweet blueberries is an intricate process full of challenges. The next time you enjoy fresh blueberries, remember the care and effort it took to produce them!

Fun Blueberry Superlatives

Blueberries have some fun and impressive superlative bragging rights. Here are just a few of the ways blueberries outrank their berry competition:

Superior antioxidant – Blueberries rank #1 among fresh fruits and vegetables for antioxidant power. Their ORAC score is 2-5x greater than similar-sized berries.
America’s #1 berry crop – Blueberries are the #1 berry crop in North America based on annual production volume, generating valued at $720 million (in 2021)
Biggest producer – North America produces nearly 180 million pounds of wild blueberries per year, more than any other region. Maine alone provides 10% of all globally grown blueberries.
Most prolific shrub – A mature highbush blueberry plant can produce up to 15,000 berries per bush in peak season, enough for more than 100 pints of berries.
Most natural color – Unlike other blue foods, the distinctive navy hue of blueberries comes entirely from their natural pigments anthocyanins and carotenoids. No artificial colors were added!
Official July birthstone – The deep blue hue of blueberries inspired the American Gem Trade Association to designate blueberries as the official birthstone for July.
State berries – Blueberries are the official state berries of New Jersey and Maine, which are among the top blueberry-producing states.
Olympian blueberries – At the 2008 Beijing Olympics, Maine wild blueberries were featured on the menus for the U.S. Olympic team training table.
