Carex vir-Carex virgata (swamp sedge)

Carex virgata, commonly known as swamp sedge or pukio, is a vigorous, tussock‑forming New Zealand native sedge with narrow, bright green, arching leaves. This hardy, evergreen species thrives in damp to very wet environments, including swamps, drains, wetlands, seepages, and stream margins. Despite its preference for wet conditions, it is also surprisingly tolerant of periodic dryness, making it a versatile choice for a wide range of planting sites.

Highly valued for restoration and landscaping, C. virgata excels in:

  • Wetland and riparian planting
  • Erosion control
  • Stabilising streambanks and drain margins
  • Forming dense, attractive clumps in both natural and designed landscapes

Durable, adaptable, and fast‑establishing, Carex virgata is an essential species for ecological projects across Aotearoa.
