Kūmarahou (Pomaderris kumeraho)

Kūmarahou or gum digger’s soap is a 3m shrub found only in the North Island. Inconspicuous for most of the year, it bursts out with bunches of beautiful yellow flowers in spring. Grows in poor quality soils, usually along road sides.



  • A magical plant – when boiled down with water the resulting bitter tonic is extremely powerful in treating respiratory problems like asthma, coughs, sore throats and colds.
  • Rub the blooming flowers between your hands with water to create an ‘in-a-pinch’ bush soap
