- 🌱 The striking variegation appears immediately on new spring shoots and intensifies throughout the growing season, with burgundy tones developing in response to cooler fall temperatures.
- 🌱 This grass is rhizomatous and expands slowly and predictably, making it safe for mixed borders and containers, unlike aggressive spreading grass species.
