A Bumper Year for Kumarahou

It has been a very good year for our local cream-coloured kumarahou.  Found naturally only in the Warkworth-north Rodney area, Pomaderris hamiltoni is a different species from the well-known bright yellow kumarahou common on clay banks and roadsides in other districts.

The cream-coloured flowers of the local Hamilton’s kumarahou are distinctive on clay banks and roadsides at this time of year. This colony is on the Leigh road between Matakana and Whangateau.

Hamilton’s kumarahou grows taller and thinner than the more widespread species, but likes the same habitat of dry clay banks. There are some lovely displays locally, particularly on the Leigh road on the highest part between Matakana and Whangateau, and on the Sandspit road.

They have a fairly short flowering season so they will be fading fast. When not in flower they are hard to notice and are often at risk of roadside spraying programmes because most people would pass them over as weeds or scrub. But in spring when they flower they become much more obvious.

Hamilton’s kumarahou is a local botanical treasure which we should all recognize and appreciate.

  1. Pomaderris hamiltonii is found naturally only at Whangateau, Ahuroa and Coromandel. There are isolated specimens on the Sandspit Road and elsewhere in this district.
    Early settlers used kumarahou to relieve coughs and bronchitis and, most usefully, as a soap substitute.

    Some of the densest patches are on the Sandspit Road and the nearby James Street closer to Snells. These patches are now better than the Whangateau ones. I had forgotten about the Coromandel occurrence.
