Macropiper psittacorum is a subspecies of kawakawa found on the northern offshore islands. It is similar in form to M.Excelsum, the differences being that it has a slightly longer flower spike, has slightly larger, thicker leaves with more pronounced veining in the leaves and branches more like a vine. It may be less prone to catapillar damage. It forms a densely branched shrub of about 2m. Male and female flowers are carried on separate spikes, often on separate plants. They are very tiny and tightly packed on upright spikes, and on the female become an attractive orange ‘candle’ of berries adding to the trees ornamental appearance. Kawakawa is an excellent choice for shady areas, where it looks best. Frost Tender. Propagation by seeds or cuttings.
