Bog whortleberry, also known as marsh whortleberry, moorberry, and lowbush blueberry, is a type of shrub that grows in wetlands and acidic soils. The plant produces small, tart berries that are similar in taste to blueberries, but smaller in size. Other synonyms for bog whortleberry include bearberry, bilberry, and huckleberry. These names are often used interchangeably, but they may refer to different species of shrubs depending on the region. Despite their small size, bog whortleberries are highly nutritious and have been used in traditional medicine for their anti-inflammatory and antioxidant properties. They are also a popular ingredient in pies, jams, and other desserts.
