Disphyma australe,  horokaka,  or New Zealand ice plant is endemic to the Three Kings, North, South, Stewart and Chatham Islands. It is found in coastal areas (rarely inland), mostly on cliff faces, rock stacks, and boulder/cobble beaches, more rarely in saltmarsh and estuaries. Often in petrel scrub on offshore islands, and extending into coastal forest around petrel burrows. Occasionally on limestone or sandstone cliffs in lowland forest (Western Waikato). A  more or less succulent trailing, many-branched perennial herb that forms spreading patches  more than a metre across, with thick succulent roundedly triangular green leaves, that can often be stained red especially when growing in full sun. It has bright to pale pink flowers (rarely white) from October to December, sometimes through to April, that are followed by succulent seed capsules from December to April that mature dry and hard, but open when wet and close when dry. In a garden situation, it likes well-drained soil in a sunny position and will withstand considerable drought making it great for dry areas of the garden or sandy coastal gardens. Unfortunately it can be rather frost-tender is regions that suffer severe frosts.
