Distribution
Indigenous. In New Zealand scattered throughout from the Three Kings and North Island, south to Marlborough in the South Island. Recently (1998) discovered on Norfolk Island
Habitat
Usually coastal on rocky headlands, cliff faces and boulderfield. Shows a distinct preference for basalt, limestone and ultramafic rocks but can also be common around bird nesting grounds. Often found inland on limestone outcrops in the Waikato, and on apatite-rich greywacke rock facies around Wellington and the Wairarapa
Propagation technique
Easy from fresh seed and rooted pieces. A very attractive grass for a sunny, well drained place within a rockery, or within a hanging basket.
Threats
Not Threatened but has declined over the northern part of its range
Etymology
