Fun Facts
- 🌱 Million Bells earned its common name from the sheer abundance of blooms—a single plant can produce over 1,000 flowers per season in ideal conditions.
- 🌱 Calibrachoa is a relatively modern genus created through deliberate hybrid crosses between wild Petunia and Calibrachoa species; it was formally recognized in the 1990s.
- 🌱 Unlike petunias, Million Bells have a trailing habit and are self-cleaning on many cultivars, meaning spent flowers fall away naturally without deadheading.
