This plant spreads using subterranean stems and forms mats in suitable areas. Its habitat is among the high, bleak tussock grasslands of central South Island, growing between tussocks and around rock outcrops. It can be distinguished from its closest congeners by the glaucous leaves with red teeth and its spreading, mat-forming (rather than compact) habit. Flowering occurs in January with fruit being produced in February and March.[1]
Conservation status
In 2018, it was classified as "Not Threatened" under the New Zealand Threat Classification System.[2]
