Northern vs Southern vs Rabbiteye Blueberries
| Northern Highbush | Southern Highbush | Rabbiteye | |
|---|---|---|---|
| Zones | 3–7 (cold half of 8) | 5–10 by variety | 7–9 |
| Chill hours | 800–1,000+ | 150–600 | 350–700 |
| Mature size | 4–7 ft | 4–6 ft (dwarfs 3 ft) | 6–10 ft unpruned |
| Pollination | Self-fertile; better in pairs | Self-fertile; better in pairs | Needs a different rabbiteye variety |
| Harvest | Mid-summer core season | Earliest — spring into early summer in the South | Early summer through late |
| Best at | Benchmark flavor, cold climates | Warm climates, early fruit, patios (dwarfs) | Heat, humidity, toughness, big crops |
Verdict: choose by winter first. If your area reliably gets 800+ chill hours and zone 7-or-colder winters, northern types give you the classic berry. Below ~600 hours, southern highbush is the reliable path; in the hot, humid Southeast with room for big bushes, rabbiteyes out-tough everything.
