Fun Facts
- 🌱 Dianthus is often called 'Pink' because of the serrated or 'pinked' edges of its petals, created by the fringed margins that look like they were cut with pinking shears.
- 🌱 The sweet clove-like fragrance of dianthus comes from volatile compounds similar to those found in actual clove spices, making it aromatic enough to detect from several feet away.
- 🌱 Crimson Ace is a hybrid dianthus (Chinese Pink crossed with other species), bred specifically for compact size, prolific blooming, and vivid color—it cannot reproduce from seeds true to type.
