- Te Ao Māori
- Montia australasica has no recognised Māori name. It grows in damp forest and wetlands, areas rich in resources for Māori. The plant would have been known but not distinctively named.
It creeps across damp ground. Montia australasica, white purslane, is soft and slightly succulent. It is a damp ground specialist. It grows in wet places. Along stream banks. In seepages. In damp forest. It spreads across the ground. Forming a soft green mat.
The leaves are small, fleshy, and bright green. They are succulent. Storing water. The stems creep along the ground. Rooting at nodes. The flowers are small and white. With five petals. They appear in spring and summer.
Montia australasica grows in damp forests. Along stream banks. In wetlands. It likes moisture. It does not like drying out.
The name australasica means from Australasia. The plant is found in New Zealand and Australia.
White purslane is native to New Zealand and Australia. It belongs here.
In gardens, Montia australasica is valued as a ground cover for damp, shady areas. It grows in rain gardens. It grows along pond edges. It grows where other plants struggle.
The plant is not threatened. It is locally common. But wetland drainage reduces its habitat.
Montia australasica is a reminder. Damp places have their own plants. Soft. Creeping. Succulent. Tolerant of wet feet.
The seepage is wet. The purslane spreads. Soft green leaves. Small white flowers. The water flows. The plant drinks. It does not mind the wet. It has been here for millennia. It will be here as long as the water flows.
It just stays moist. That is enough.
