Overview:
Carex secta, commonly known as Pukio or Swamp Sedge, is a striking New Zealand native wetland plant known for its distinctive raised “pedestal” growth habit. Naturally found in swamps, lake margins, and slow-moving waterways, it forms impressive golden-green tussocks that elevate above wet ground. Ideal for restoration projects, rain gardens, and pond edges, this bold sedge brings strong architectural structure to moisture-rich landscapes.
Key Features:
Foliage: Long, arching, golden-green to olive-green leaves forming dense tussocks.
Flowers / Fruit: Brown flowering spikes appear in spring and early summer.
Form & Habit: Large, upright clumps that develop elevated bases over time in wet conditions.
Growth Rate: Moderate to fast in wet soils.
Cultural & Ecological Value: Excellent for wetland restoration, erosion control, water filtration, and providing habitat for native wildlife.
