Why You’ll Love It

Growing to 3–4 metres high, this giant grass forms dense clumps of mid-green leaves that sway beautifully in the wind, creating both sound and motion in the garden. In late summer to autumn, tall flower plumes emerge, silvery at first before maturing to soft bronze tones, providing striking seasonal interest that persists into winter. Its imposing stature makes it ideal for creating privacy screens, backdrops, or dramatic architectural statements in larger garden spaces.

Planting & Care Tips

  • Plant in full sun with well-drained soil

  • Water during establishment, then reduce once established

  • Leave foliage and plumes standing through winter for structure

  • Cut back hard in late winter before new growth emerges

  • Space generously to allow full clump development
