Growth Stages

1

Dormancy/Early Spring

December-March

Plant is dormant underground with rhizomes. Cut back old growth from previous year to 4-6 inches above ground in late winter/early spring.

Cut back before new growth emerges. Clean up dead foliage to prevent disease and allow new shoots to emerge easily.

2

Sprouting & Early Growth

April-May

New shoots emerge from ground in spring, showing characteristic cream and green striping immediately.

Water regularly to support shoot development. Apply balanced fertilizer in early spring. Remove any winter debris.

3

Vegetative Growth

June-August

Rapid stem and leaf development throughout summer; plant grows taller with increasingly prominent variegated striping.

Water consistently during dry periods. No fertilizer needed once established. Monitor for any pest issues. Provide staking in windy areas if needed.

4

Fall Color Change & Maturity

September-November

Foliage develops reddish-burgundy tones while maintaining cream-green striping. Plant reaches full height of 4-6 feet.

Reduce watering as temperatures cool. Do not cut back; leave standing for winter interest and wildlife shelter.

5

Winter & Dormancy

December-February

Plant remains standing with dried foliage displaying warm tan and burgundy colors throughout winter.

Leave standing for winter interest and to protect rhizomes. Do not cut back until late winter when new growth appears.

Fun Facts

  • 🌱 Autumn Twist is a sterile hybrid, meaning it produces no viable seeds—a major advantage over other Miscanthus varieties that can become invasive in some regions.
  • 🌱 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.
