Te Ao Māori
In Māori tradition native chickweed used as green vegetable. Leaves and stems eaten fresh or cooked. Plant also used medicinally as poultice for wounds and skin irritations. Name refers to chickweed-like appearance. Known as sign of healthy, damp soils. Plant of stream banks. Gathered by those who knew water's edge.
It does not inhabit the dry exclusively. Stellaria decipiens is small, trailing herb. Pairs of pointed leaves. Plant that looks like weed. Plant that is useful. Leaves and stems are edible. Mild, spinach-like flavour. Can be eaten raw in salads or cooked as green vegetable. Very similar to introduced chickweed or Stellaria media but has slightly larger flowers. Native that is easy to mistake for invader. Leaves arranged in opposite pairs along stem. Each pair at right angles to pair below. Leaves pointed and bright green. Stems slender and trailing. Rooting at nodes. Forming loose mats. Plant that spreads without asking permission. Flowers small and white. Five petals deeply divided. Making them look like ten petals. Appear in spring and summer. Followed by small, capsule-like fruits containing seeds. Flower that pretends to have more petals than it does. Native chickweed very similar to introduced chickweed. Native species has slightly larger flowers. Less aggressive. Found in damp, open areas. Often in native grassland and at forest margins. Plant that minds its own business. To find native chickweed is to search damp margins of forests and streams. Look for trailing mats of pointed leaves. Small, star-shaped white flowers. Humble plant but useful. Handful of leaves can add mild, spinach-like flavour to salad or soup. Forest margin is damp. Chickweed trails between grasses. White stars scattered in green. Most people walk past without noticing. Chickweed does not mind. It was not trying to be noticed. It was just growing where ground stays wet. And that seems to be enough.
