Vaccinium corymbosum (Highbush Blueberry)

A confirmed cornerstone species of the New Jersey Pine Barrens and the wild progenitor of most cultivated blueberries, highbush blueberry is both deer resistant and a documented larval host for the Striped Hairstreak, Spring Azure, Brown Elfin, and Henry's Elfin butterflies - genuine four-season ecological and ornamental value in one shrub.

Species Overview

Vaccinium corymbosum, or highbush blueberry, is a deciduous shrub native to wetlands, forest edges, and swamps across eastern North America, typically growing 6 to 12 feet tall. White to pink, bell-shaped flowers bloom in spring, followed by large, sweet blue berries in summer above deep green foliage that turns vibrant red, orange, or yellow in fall.

Application

• New Jersey Pine Barrens and acidic wetland restoration - confirmed cornerstone species
• Larval host habitat for the Striped Hairstreak, Spring Azure, Brown Elfin, and Henry's Elfin
• Deer-pressured sites - confirmed deer resistant
• Rain garden, wetland edge, and edible-landscape plantings

Growing Conditions / Specification Data

• Light: Full Sun to Part Shade
• Soil/Moisture Tolerance: Acidic, moist soils; wetlands, forest edges, and swamps
• Plant Type: Shrub
• Mature Height: 8-15 ft.
• Fall Color: Yellow, Orange, Red
• Bloom Color / Period: White, Pink; May
• Wetland Indicator Status: NI (No Indicator) - see flags
• Native Range: Northeast/Mid-Atlantic (full list) - cornerstone New Jersey Pine Barrens species
• Hydrology: Mesic-Moist
• Root Depth: Shallow (Under 12 in.) (blueberries are well-documented as shallow, fibrous-rooted)
• Salinity Tolerance: Low
• Growth Rate: Slow
• Drought Tolerance: Low (shallow roots limit access to deep soil moisture)
• Flood Tolerance: Moderate - Can occur at wetland and bog margins in addition to drier upland sites, more moisture-tolerant than its relative lowbush blueberry; tolerates periodically wet soil.
• Shade Tolerance: Intermediate
• Growth Habit: Multi-stemmed/Thicket-forming - suckering
• USDA Hardiness Zones: 3-7
• Deer Resistance: Yes (Rarely Damaged)
• Pollinator Value: Larval host, supports bees, supports butterflies, supports moths

Planting Guidance

• Plant in groups of at least two to three for best cross-pollination and fruit set; self-fertile but produces larger berries with cross-pollination. Shallow root system benefits from rich, acidic soil kept consistently moist.
