cushions wet snowy alpine zones tight
- Size
- Height: 3-8 cm, Diameter: up to 30 cm
- Lifespan
- Perennial (slow-growing)
- Diet
- Not applicable - autotrophic. Photosynthetic cushion plant. Obtains nutrients from consistently moist alpine soils in seepages and damp scree.
- Habitat
- Alpine and subalpine areas, particularly in wet, snowy zones. Grows on rocky slopes, in seepages, and on damp scree. Prefers consistently moist soils.
- Range
- Endemic to New Zealand. Found in alpine and subalpine areas of the South Island, from Nelson to Southland in high mountain regions.
- Endemism
- Endemic
- Main Threats
- Climate change is the primary threat. Alpine habitats are warming. Snow patches are retreating, reducing suitable habitat for this moisture-dependent species.
- Population
- Found in alpine areas of the South Island. Locally common in suitable wet habitats. Not threatened but vulnerable to long-term climate shifts.
- Conservation Status
- data_deficient
- Human Risk
- harmless
- Handling Note
- protected alpine cushion plant, do not walk on or disturb
- Conservation Note
- Endemic alpine cushion plant; data insufficient for full threat classification.

- Te Ao Māori
- Donatia novae-zelandiae has no recognised Māori name. The alpine zone was not heavily used by Māori. The snow cushion plant grows in the wettest, coldest places. It is part of the high mountain ecosystem and is treated with respect by those who visit these remote areas.
Dense, bright green mounds in wet alpine zones. Looks soft. Lies. Donatia novae-zelandiae forms tight cushions that look like velvet from a distance. Touch them. They are firm, not soft. The plant is dense, compact, built to survive.
The leaves are small, narrow, bright green, crowded on the stems. The cushions are domed and smooth. The flowers are small, white, star-shaped. They are held just above the cushion. They appear in summer.
Donatia novae-zelandiae grows in wet alpine zones. Seepages. Damp scree. Snow patches. It likes moisture. It likes cold. It does not like drying out. The name novae-zelandiae means of New Zealand. The plant is named for its home.
The species is endemic to New Zealand. It is found only in the South Island mountains. In the alpine zone, it grows in the wettest places. It is often found near snowmelt streams. It is a specialist.
The genus Donatia is named for Donat, a French botanist. The plant is small. It is obscure. It is beautiful. Snow cushion plant is not threatened. It is common in suitable habitat. But alpine areas are threatened by climate change.
Donatia novae-zelandiae is a reminder. The wettest alpine zones have their own plants. Dense. Green. Soft-looking. Deceptive.
Do not walk on it. Keep your distance. It is protected.
It keeps going.
