Star Blueberry is a patented Southern Highbush cultivar bred from Vaccinium formosum crossed with corymbosum, selected in Florida for performance in mild winter climates. It earns its name from the distinctive star shape visible at the blossom end of each large, sweet berry. Hardy in zones 7-9 and requiring full sun and consistently moist, acidic soil (pH 4.5-5.5), this vigorous bush grows 6-7 feet tall and blooms early in July, making it especially valuable for maritime regions of the Pacific Northwest and California where low chill hours are the norm.

Each berry displays a pronounced star shape at its blossom end, a distinctive visual marker that makes hand-harvesting quick and satisfying. Star thrives in the cool, mild winters of maritime climates where many blueberries struggle, flowering reliably in July despite minimal chill requirements. The berries themselves are notably large and flavorful with excellent ripening concentration, so you can harvest most of the crop in a single pass rather than making multiple rounds through the bush.
Star berries are eaten fresh off the bush, where their large size and pronounced sweetness make them satisfying to snack on. Their good ripening concentration means most berries ripen within a narrow window, making them practical for home preserving in jam or for freezing. Hand-harvesting is straightforward thanks to their size and the distinctive star marking, so they work well for pick-your-own scenarios or gardens where you enjoy harvesting by hand.

Transplant container-grown Star Blueberry in early spring or fall, after hardening off if it has been in a greenhouse or nursery environment. Choose a spot with full sun and prepare soil with abundant peat moss or sulfur to reach the required 4.5-5.5 pH range. Space plants 4-6 feet apart and plant at the same depth they were growing in their nursery container, firming soil gently around the root ball.
Harvest Star berries in July when they are fully dark blue (not red or purple) and have developed their characteristic sweetness; berries will feel slightly soft when gently rolled in your palm but should not be mushy. Because of the excellent ripening concentration, most berries will reach peak ripeness within a short window, allowing you to harvest the majority in one or two passes. Cup your hand under each cluster and gently roll ripe berries into your palm; they'll detach easily when truly ready. The distinctive star marking at the blossom end makes it easy to spot fully mature berries.
Prune Star Blueberry in late winter or early spring before new growth begins, removing any dead or damaged canes and crossing branches to open up the interior of the bush for light and air circulation. Thin older canes to encourage productive new growth, as blueberries fruit on one-year-old wood. Keep the bush at a manageable height of 6-7 feet by selectively heading back tall canes; Star's strong growth habit will quickly respond with vigorous new shoots.

“Star is a patented selection developed in Florida, engineered specifically for gardeners in mild-winter regions who couldn't reliably grow traditional highbush blueberries. Its parentage, crossing Vaccinium formosum with the standard V. corymbosum, gave it the low-chill characteristics of southern genetics while maintaining the vigor and berry quality of northern highbush types. The variety has become a leading choice among Southern Highbush blueberries precisely because it solved a real problem: giving Pacific Northwest and California gardeners a reliable, productive blueberry that doesn't demand the hard freezes other varieties need.”
