Canterbury Bells are biennials, meaning they complete their life cycle in two years. In the first year, they produce a rosette of foliage, and in the second year, they send up tall, upright flower stalks adorned with bell-shaped flowers. These flowers come in shades of blue, purple, pink, and white. They are primarily grown as outdoor garden plants, adding a cottage garden charm. While technically possible to grow indoors, they require very bright light and cool temperatures to thrive, making it challenging.
