Cloudberry (Rubus chamaemorus) is a rare northern berry plant prized for its amber-gold, soft, and sweet-tart fruits. Native to Arctic and subarctic regions, this hardy perennial produces delicate white flowers in spring, followed by unique golden berries in summer. Highly valued for their vitamin-rich flavor, cloudberries are perfect for jams, desserts, and preserves. They thrive in cool, moist, acidic soils, making them a beautiful and productive choice for temperate gardens or containers.
