Kūmarahou (Pomaderris kumeraho) is one of the harbingers of spring along the roadsides of the Waitakeres. Starting out as the palest yellow blush when in bud, the colour intensifies as the flowers open.
The plants are shrubs or small trees. They are also known as “gum diggers soap”, because, apparently, the flowers will lather up when rubbed with water. Leaves of the plant have uses in Maori medicine.
Unlike many of the blossom I like and photograph, this one is not a weed.
