Ficinia nodosa, commonly known as Knobby Club Rush or Knotted Club Rush, is a tough, evergreen, perennial sedge native to Australia and New Zealand. It is highly valued for its adaptability to coastal and wetland environments, making it a popular choice for landscaping and erosion control.
Key Characteristics:
- Growth Habit: A clumping, tufted rush with upright, narrow, cylindrical stems.
- Height: Typically grows between 50 cm and 1.5 meters.
