Superior Blueberry
Superior Blueberry
Large, Late-Season Berries on a Vigorous Minnesota Half-High
Superior Blueberry (Vaccinium 'Superior') is a vigorous University of Minnesota half-high that ripens late in the season, extending your blueberry harvest with large, firm, flavorful berries. It's tall for a half-high, very cold-hardy, and finishes the season with rich red fall color. Give it acidic soil and a second variety nearby for the best crop. Whether you're rounding out a berry patch in Edina, filling a sunny bed in Maple Grove, or adding a late-fruiting shrub in Woodbury — Superior stretches the blueberry season in zone 4b–5a (and colder) gardens.
Superior Blueberry Plant Details
| Attribute | Detail |
|---|---|
| Scientific Name | Vaccinium 'Superior' (half-high, U of MN) |
| Plant Type | Deciduous fruiting shrub (half-high blueberry) |
| Mature Height | 4–5 feet |
| Mature Width | 3–4 feet |
| Sun | Full sun (6+ hours) for the best yields and sweetness |
| Water | Moderate to high — 1–2 inches per week; shallow roots need steady moisture |
| USDA Zones | 3–7 (Twin Cities is zone 4b–5a) |
| Soil | Acidic, pH 4.5–5.2 — essential. Most Minnesota soils are too alkaline; amend heavily with peat and elemental sulfur. |
| Pollination | Self-fertile but yields far better with a second blueberry variety nearby |

| Fall Color | Rich red foliage |
| Winter Hardiness | Reliable to zone 3 |
Superior Blueberry Uses in Minnesota Gardens
Extending the harvest
As a late ripener, Superior caps off the season after early types like Saint Cloud finish, giving a Plymouth garden weeks more fresh fruit.
Cold-climate berry patch
Tall and vigorous yet zone 3 hardy, it's a productive backbone shrub. Plant with another half-high for cross-pollination.
Raised beds and edible landscaping
Acidic raised beds suit it best in the Twin Cities, and its size and fall color make it an attractive edible-landscape shrub in Eden Prairie.
Best Time to Plant Superior Blueberry in Minnesota
Spring (late April–May) is the best window, giving the shrub a full season to establish. Early fall planting can work in a sheltered spot, but spring is safer. Never plant after mid-October.
How to Plant Superior Blueberry
- Test and acidify the soil first — blueberries need pH 4.5–5.2. Mix in peat moss and apply elemental sulfur ahead of planting.
- Dig wide, not deep, and backfill with a 50/50 blend of native soil and acidic peat/compost.
- Plant a second variety within a few feet for cross-pollination.
- Set the crown level with the soil and water in well.
- Mulch 3–4 inches with acidic mulch — pine bark, pine needles, or sawdust — kept off the stems.
- Pinch first-year blooms so the plant builds roots before fruiting.
Watering Superior Blueberry in Minnesota
First Year Watering Schedule
- Weeks 1–2: Every 1–2 days, deep and slow
- Month 1–2: Every 3–4 days
- Month 3–6: 1–2 inches per week; blueberries have shallow roots and dislike drying out
- Stop watering 2–3 weeks before ground freeze (typically late October in the Twin Cities).
After Year One
Keep soil consistently moist, especially during fruit set and ripening. Use rainwater if your tap water is alkaline, since hard water gradually raises soil pH.
Why plant a late variety?
Pairing Superior with an early type like Saint Cloud can stretch your fresh-blueberry harvest across much of the summer.
Do I need a second variety?
It fruits alone but yields more with a partner. Any zone 3–4 half-high or highbush blooming at the same time works as a pollinator.
Will it survive a Minnesota winter?
Yes — hardy to zone 3. Mulch in-ground plants; protect container roots over winter.
