Last updated

Bog blueberry (bog bilberry) is a native broadleaf shrub reaching 2 ft with multiple stems and semi-erect form. It produces urn-shaped white to pink flowers and blue edible berries with dark green foliage.

Bog blueberry is hardy in zones 2a-8b and thrives in sun to part shade with well-drained, acidic soil (pH 4.5-5.7) and moderate moisture. Growth is moderate with low drought tolerance, suiting it to naturally moist conditions. Large quantities of fruit may cause headaches due to fungal infestation.
