Fun Facts
- 🌱 Wave petunias were introduced in the 1990s by seed companies as a breakthrough in petunia breeding, revolutionizing container gardening with their vigorous spreading habit—they can cover 2-3 times more area than traditional petunias.
- 🌱 Petunias come from South America and were named from the Tupi word 'petum' meaning tobacco plant, as they are botanically related to tobacco.
- 🌱 Wave Pink flowers remain open during the day and close at night, and individual blooms last only about 2 days before dropping, but the plant continuously produces new flowers all season.
