Campanula is a genus of flowering plants in the Campanulaceae family, which includes more than 300 species. Commonly referred to as bellflowers, campanulas are popular garden plants known for their delicate, bell-shaped flowers that come in shades of blue, purple, pink, and white.

Most campanulas prefer full sun to partial shade, and they thrive in well-draining soil. They are generally low maintenance plants that do not require frequent watering or fertilizing. However, some species may require regular deadheading to encourage prolonged blooming and to prevent self-seeding.
