Produced by Humboldt Seed Co., Blueberry Muffin—sometimes called Blueberry Muffins—is an indica-dominant cross of Blueberry and Purple Panty Dropper. Revered for its uniform bud structure and purple-tinted flowers, this cross smells like a tray of fresh baked muffins. Its berry sweetness is softened by a smooth, creamy finish and makes for a tasty joint.
