Apium prostratum or Shore parsley is indigenous, and is known from the Kermadec, Three Kings, North, South, Stewart and Antipodes Islands. It is also found in eastern Australia as far north as Brisbane and along the whole coastline of southern Australia and Tasmania. It grows in coastal and lowland regions, very rarely montane. It is common on rock ledges, boulder falls, cliff faces, within petrel scrub on damp seepages, in peaty turf, saltmarshes, within estuaries on mud banks, around brackish ponds, and lagoons. Also found in freshwater systems such as around lake and tarn sides, along streams and rivers and in wet hollows occasionally well inland, and sometimes at considerable elevations. A variable, fleshy perennial herb with sprawling stems and glossy green leaves, it is easily grown from fresh seed and whole plants.  It is edible and pleasant tasting so it could be more widely used as a substitute for celery.
