  • groundlayer to forest garden
  • use to stabilise soils, reduce the erosive impact of heavy rain, retain soil moisture and shade soils to reduce high summer temperatures.

Notes: May be less vigorous growth in the cool season. Reportedly used by Captain James Cook’s crew to combat scurvy on arrival at Botany Bay, Australia, in 1770. Expedition botanist, Joseph Banks, took seeds back to Kew Gardens in London.

New Zealand spinach is grown in a number of countries and has been commercially cropped in Europe. It is a common plant of the coastal zone and is wild-harvested.

If wild harvesting does not over-harvest so as there is some left for others and to avoid environmental damage.
