6-8 weeks (summer to early fall)Tall, feathery plumes emerge above foliage in mid to late summer, initially purple-tinged, maturing to cream
Plumes are self-supporting. Avoid cutting or pruning during flowering. Leave inflorescences for winter interest.
Mature Tussock
Year 3 onwards (indefinite)Fully established plant forms a dense, upright mound 3-4 feet tall with consistent reddish coloring and persistent plumes
Minimal maintenance required. Can last 20+ years. Remove dead outer leaves if desired. Do not cut back severely.

Harvest Tips
Red Tussock Grass is an ornamental; no harvesting for consumption. Cut flowering plumes in late summer or early fall when they have matured to cream color for dried arrangements. Remove plumes before they shed seed if you want to prevent volunteer seedlings. Prune dead outer leaves selectively; never cut back the main crown.
Fun Facts
- 🌱 Red Tussock Grass is endemic to the South Island of New Zealand, growing naturally above 2,600 feet elevation in alpine tussock grasslands—one of the harshest environments in the Southern Hemisphere.
- 🌱 The distinctive reddish coloring intensifies in cooler weather and at higher altitudes, serving as an adaptive response to UV exposure in New Zealand's thin, high-altitude atmosphere.
- 🌱 Chionochloa species can live for 20-40+ years in cultivation, making them exceptionally long-lived ornamental grasses that improve with age, forming increasingly sculptural mounds.
