The Dwarf Bilberry (Vaccinium caespitosum), also known as the Dwarf Blueberry or Whortleberry, is a hardy, low-growing evergreen shrub native to North America. It produces small, sweet, edible blue berries similar to wild blueberries, making it an excellent choice for naturalized gardens, containers, or cool-climate landscapes.
These non-GMO bilberry seeds produce compact plants ideal for ground cover, alpine gardens, or wildlife habitats. Its glossy green leaves turn shades of red in fall, providing year-round beauty and productivity.
