Types of Blueberries

The five types of blueberries grown in the US

There are five main types of blueberries suited to US home gardens: northern highbush, southern highbush, half-high, lowbush, and rabbiteye. The right type depends entirely on your USDA hardiness zone and local climate.

The blueberry is one of the few fruits native to North America, and the diversity of species reflects thousands of years of adaptation across the continent — from the subarctic tundra to the Florida coast. That range means there’s a blueberry suited to nearly every US garden, but only if you match the species to your climate.

This guide covers what each type looks like, where it grows best, which varieties perform best for US home gardeners, and what all blueberries share in common regardless of type.

Northern highbush blueberries (Vaccinium corymbosum)

Northern highbush is the most widely grown blueberry type in the US. It produces the large, firm berries found in grocery stores and grows best in Zones 4–7 with cold winters and moderate summers.

Northern highbush plants reach 4–6 feet tall at maturity and produce berries from late June through August depending on variety and zone. They require 800–1,000 chilling hours (temperatures below 45°F) per winter to break dormancy and bloom properly. This requirement makes them the wrong choice for gardeners in the deep South or warm coastal climates.

States where northern highbush performs best: Michigan, New Jersey, Oregon, Washington, Maine, Massachusetts, and the upper Midwest.

Chandler is worth noting for home gardeners: its berries regularly reach 1 inch in diameter, among the largest of any blueberry variety. Patriot is the most cold-hardy northern highbush, surviving Zone 3 winters when established.

Southern highbush blueberries (Vaccinium corymbosum hybrids)

Southern highbush blueberries were bred to produce large, high-quality berries with low chilling hour requirements — 150–300 hours — making them the right choice for gardeners in Zones 7–10.

Southern highbush is a hybrid developed by crossing northern highbush with native southeastern US species. The result is a plant that tolerates the heat of the Southeast and Gulf Coast while still producing the large berries consumers expect.

Best-producing states: Florida, Georgia, California, Texas, and the Carolinas.

Sunshine Blue is a standout for southern gardeners: it’s self-fertile, stays compact at 3 feet tall (suitable for large containers), and tolerates a wider pH range than most blueberries. It remains productive even in partial shade, which is rare among blueberries.

Rabbiteye blueberries (Vaccinium virgatum)

Rabbiteye blueberries are the most heat- and drought-tolerant blueberry type, thriving in Zones 7–9 across the Southeast. They grow larger than highbush plants — up to 10–15 feet without pruning — and require two varieties for cross-pollination.

The name “rabbiteye” comes from the pink blush on immature berries before they ripen to blue, said to resemble a rabbit’s pink eye. These plants are extremely long-lived — documented specimens over 50 years old still produce commercially — and tolerant of Alabama clay, Georgia red dirt, and the high summer heat of the Gulf Coast.

Rabbiteye requires two compatible varieties for reliable fruit set. Planting a single rabbiteye variety produces very little fruit.

Tifblue and Brightwell are the most widely planted commercial rabbiteye combination in the Southeast. For home gardeners, Climax and Brightwell or Premier and Powderblue work well as pairs. Plant selections within the same ripening window for the best overlap in bloom time.

Half-high blueberries (Vaccinium corymbosum × V. angustifolium hybrids)

Half-high blueberries cross northern highbush with lowbush to produce compact plants — 2–4 feet tall — with exceptional cold hardiness for Zones 3–5. They deliver bigger berries than lowbush with better cold tolerance than highbush.

Half-high varieties were developed specifically for gardeners in the northern US and Canada who want larger berries but experience winters too severe for standard highbush. They survive temperatures down to -35°F and -40°F depending on variety, making them viable in Minnesota, North Dakota, Wisconsin, and upper Michigan.

Northsky is the right choice for container growing in cold climates — it stays under 2 feet and survives containers when moved to a cold garage or unheated porch during the deepest winter months.

Lowbush blueberries (Vaccinium angustifolium)

Lowbush blueberries are the wild blueberries of Maine and eastern Canada — low-growing ground covers under 18 inches tall, intensely flavored, and hardy to Zone 3. They spread by underground rhizomes rather than seeding, forming patches over time.

The “wild blueberries” sold frozen in grocery stores are almost exclusively lowbush. Their smaller size — pea-sized or smaller — concentrates flavor compounds and antioxidants more intensely than highbush types. University of Maine research shows wild lowbush blueberries have 33% more antioxidant capacity per gram than cultivated highbush types.

Lowbush blueberries don’t grow as individual plants in the garden sense — they spread as a colony. They’re suited to acid soil, rocky hillsides, and naturalized areas in the North. They don’t fit a traditional garden bed well but excel as:

• Ground cover on slopes where mowing is difficult
• Naturalized patches at the edge of a wooded property
• Mass planting under acid-loving trees like oaks and pines

You’ll find lowbush plants and sod-cuts available through Maine specialty nurseries and northeastern extension programs. They’re not widely sold at chain garden centers. Chippewa and Northsky half-high types are often a better fit when gardeners want smaller plants with manageable spread.

How to choose the right blueberry type for your zone

Matching blueberry type to USDA zone is the single most important selection decision. A northern highbush planted in Zone 8 never gets enough chilling hours and produces nearly nothing. A rabbiteye planted in Zone 5 may survive a mild winter and fail in a cold one.

For gardeners in Zone 7, you’re in the transition zone between highbush and rabbiteye. Both types work. Highbush varieties give you larger, milder berries with earlier ripening. Rabbiteye varieties give you stronger heat and drought tolerance and longer production into August and September.

What all blueberries need regardless of type

Five requirements apply across all blueberry types:

1. Acidic soil (pH 4.5–5.5). This is non-negotiable. Test soil pH before planting with a home test kit or through your local county extension office. Most US soils test between 6.0 and 7.0 — too alkaline for blueberries. Lower pH with elemental sulfur mixed into the top 6 inches of soil, 6–12 months before planting if possible. Acidifying fertilizers like ammonium sulfate maintain pH once established.

2. Full sun (6–8 hours minimum). Blueberries produce best with 8 hours of direct sun. Partial shade reduces fruit production significantly. Fewer than 4 hours makes plants barely productive.

3. Cross-pollination from a second variety. Even self-fertile types like Sunshine Blue and Tifblue yield substantially more with a pollination partner. Plant two or more different varieties of the same type — two highbush, two rabbiteye, two half-high. Mixing types (planting a highbush with a rabbiteye) doesn’t work because bloom times don’t overlap reliably.

4. Consistent moisture. Blueberries have shallow, fibrous roots that dry out quickly. Mulch heavily with pine bark, wood chips, or pine needles to 3–4 inches deep around plants. Water to keep the top 6 inches of soil consistently moist during the growing season. Established plants tolerate brief drought but produce poorly under water stress.

5. Patience. Year 1 through 3 is establishment time. Plants pruned of flowers in years 1–2 develop stronger root systems and out-produce unpruned plants by year 4 onward. The 5–10-pound harvest from a mature highbush makes waiting worthwhile.

Comparing blueberry types at a glance

The US blueberry industry runs primarily on northern highbush in the Pacific Northwest and Michigan, and rabbiteye in Georgia and the Carolinas — a distribution that mirrors exactly which types thrive in each climate. Home gardeners who follow the same zone logic get the same results in their own backyard.
