Fun Facts
- 🌱 Surfinia is a registered trademark of the Suntory company (originally developed by Japan's Suntory in the 1980s), representing some of the first genetically selected trailing petunias specifically bred for ornamental container use.
- 🌱 The 'Milliflora' designation refers to the profusion of small flowers—'milli' meaning thousand, emphasizing the abundance of tiny blooms compared to standard petunias.
- 🌱 Surfinia petunias are self-cleaning flowers, meaning they naturally drop spent blooms; however, regular deadheading still encourages greater flower production and a tidier appearance.
