Te Ao Māori
In Māori tradition, mikoikoi was used for its strong, fibrous leaves. The leaves were used for weaving and for making cords. The golden-green colour was admired. The white flowers were noted. It was a plant of the coast and forest edge. Gathered by those who knew the open places. A fibre for the hands. A colour for the eyes.
Walk the coastal cliffs and forest margins. Look for the clumps of golden-green leaves. That is Libertia ixioides. A clump-forming perennial with narrow, iris-like leaves. Up to 40 centimetres in length. Smooth, leathery texture. The golden-green colour is distinctive. Brighter than most other native irises. A plant that shines without trying. The plant produces masses of delicate, white flowers on tall, branched stems in spring and summer. The flowers are small but numerous. Three white petals and yellow centres. Attractive to bees and butterflies. Followed by bright orange seed capsules. Persisting into autumn. Adding a second season of interest. A plant that gives twice. Golden-flag is very hardy and easy to grow. Tolerates a range of conditions. From coastal cliffs to open forests. Prefers moist, well-drained soils. Can survive short dry periods. The golden-green leaves provide colour even when not in flower. A plant that does not need to bloom to be noticed. The name Libertia honours Belgian botanist Marie-Anne Libert. Who studied cryptogams. Ferns, mosses, and lichens. The species name ixioides means resembling Ixia. A genus of South African irises. A plant named for a woman who studied the small things. To find Golden-flag is to walk the coastal cliffs and forest margins. Look for the clumps of golden-green leaves. The masses of white flowers. The bright orange seed capsules. It is a plant of the open places. An iris of the coast. The cliff is windy. The salt spray flies. The golden-flag does not care. It blooms anyway. White and gold against the grey rock. No one told it to stop. So it keeps going. And that seems to be enough.
