Ficinis nodosa, commonly known as knobby club-rush, is a tough, evergreen sedge native to coastal regions of New Zealand and Australia. It forms dense, upright clumps of narrow, arching, dark green leaves, creating a tidy, grass-like appearance year-round. Small, inconspicuous brown flower heads are produced on short stems in spring and summer, followed by distinctive knobbly seed heads. It prefers free-draining soils but will tolerate a wide range of conditions, from sandy coastal soils to heavier ground. Commonly used in coastal planting, mass plantings, borders, and low-maintenance landscapes, it is valued for its resilience, strong form, and suitability for challenging sites.
