Kōwhai

Kōwhai (Māori pronunciation: [kɔːɸai] or [kɔːfai]) are small woody legume trees within the genus Sophora that are native to New Zealand. There are eight species, with Sophora microphylla and S. tetraptera being the most recognised as large trees. Their natural habitat is beside streams and on the edges of forest, in lowland or mountain open areas. Kōwhai trees grow throughout the country and are a common feature in New Zealand gardens. Outside of New Zealand, kōwhai tend to be restricted to mild temperate maritime climates.

The blooms of the kōwhai are widely regarded as being New Zealand's national flower, although they have no official status as such.

The word kōwhai is also used in the Māori language for the colour yellow, because of the colour of the flowers.

The eight species of kōwhai are:

Most species of kōwhai grow to around 8 m high and have fairly smooth bark with small leaves. S. microphylla has smaller leaves (0.5–0.7 cm long by 0.3–0.4 cm wide) and flowers (2.5–3.5 cm long) than S. tetraptera, which has leaves of 1–2 cm long and flowers that are 3–5 cm long.

The very distinctive seed pods that appear after flowering are almost segmented, and each contains six or more smooth, hard seeds. Most species have yellow seeds, but Sophora prostrata has black ones. The seeds of Sophora microphylla can be very numerous and the presence of many hundreds of these distinctively yellow seeds on the ground quickly identifies the presence of a nearby kōwhai tree. Many species of kōwhai are semi-deciduous and lose most of their leaves immediately after flowering in October or November, but quickly produce new leaves. Flowering of kōwhai is staggered from July through to November, meaning each tree will get attention from birds such as tui, wood pigeon and bellbird. Tui are very attracted to kōwhai and will fly long distances to get a sip of its nectar.
