Carex secta, commonly known as the tussock sedge, is a native grass-like plant found in New Zealand. 




  • Growth Habit: Carex secta forms dense tussocks or clumps of grass-like leaves. The tussocks can vary in size, with some reaching heights of up to 1 meter or more.
  • Leaves: The leaves of tussock sedge are long and narrow, with a grass-like appearance. They are typically dark green in color and may have a slightly glossy texture.
  • Flowers: Tussock sedge produces small, inconspicuous flowers that are borne in terminal spikes or clusters. The flowers are often brown or greenish and are wind-pollinated.
  • Ecological Role: Carex secta is an important component of wetland ecosystems in New Zealand. It helps stabilize soil and prevent erosion along waterways. Additionally, it provides habitat and food for various wildlife, including birds and insects.


Growing Conditions:


  • Habitat: Tussock sedge is typically found in wetland and riparian habitats, such as swamps, bogs, and along the edges of streams and rivers.
  • Sunlight: It can tolerate a range of light conditions, from full sun to partial shade.
  • Soil: Carex secta prefers moist to wet soils and is often found in areas with high water tables. It is well-suited for clay and peaty soils commonly found in wetlands.
  • Watering: In cultivation, it benefits from regular watering to maintain consistently moist soil conditions.




  • Ecological Restoration: Tussock sedge is frequently used in ecological restoration projects to revegetate wetland and riparian areas and enhance their ecological functions.
  • Landscaping: It can also be used in landscaping to create water features, enhance the appearance of wet areas in gardens, or stabilize the banks of water bodies.


Carex secta plays a vital role in New Zealand's native ecosystems, contributing to the health and stability of wetland environments. Its clumping growth habit and adaptability to wet conditions make it an important species for both ecological restoration and landscaping purposes. As a native plant, it supports local biodiversity by providing habitat and food for various species, including birds and insects.
