About
Campanula 'Royal Wave' is a low-growing perennial characterized by its dense mat of small green foliage. This variety produces large, cup-shaped flowers in a violet-blue hue with white centers, which bloom successively for an extended period. The flowers emit a pleasant fragrance. As this cultivar is sterile, it continues to flower for several weeks without the need for deadheading.
