Water
Dalmation bellflower prefers moderate levels of moisture. While it can tolerate short periods of dryness, it’s essential to water it regularly, especially during hot and dry spells. Proper watering is crucial during the plant’s establishment phase and in periods of extended drought.
Sunlight
This variety of Campanula portenschlagiana thrives in full to partial sunlight. It requires at least 4-6 hours of direct sunlight daily to ensure healthy growth and prolific flowering. Adequate sunlight also enhances the vibrancy of its golden foliage.
