Native – Endemic taxon
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.

Simplified description
Rosette forming perennial herb with ground level pale green leaves. The spoon-shaped leaves have a somewhat woolly margin providing a white border. A single flower spike grows centrally into a compound head of white florets. When ripe the seeds become airborne via a tail similar to a badminton shuttlecock.
Flower colours
White
Detailed description
Rosette forming rhizomatous perennial herb. Leaves approximately 10-15 × 2 cm, obovate-spathulate, cuneately narrowed to petiole, surfaces with sparse cottony and subhispid hairs, woolly margin narrow but distinct. Scape bracts narrow-obovate to elliptic. Scapes 150-450 mm, long, 2-3 mm diameter, sparsely floccose, becoming glabrous. Inflorescence a solitary terminal glomerule, approximately 20 mm diameter. Achenes obovate, circular to oval in cross section, 1.4-1.7 mm long, densely silky-hairy, nut-brown to brown, pappus 3.2-3.5 mm long.
Similar taxa
Most likely to be confused with Craspedia uniflora var. maritima, which overlap with this species on the Southernmost parts of the Eastern Wellington Harbour. C. uniflora var. grandis when in bloom is easily distinguished as the flowers are white, compared to C. uniflora var. maritima which are yellow. The leaves are slightly different too, the woolly margin of each blade is generally not very obvious in this species, and is very obvious in C. uniflora var. maritima, a detail which can be troublesome if you are not familiar with both species.
Distribution
Endemic. Te Ika-a-Māui | North Island, Raukumara, Huirau, Tararua and Remutaka Ranges to Wairarapa and coastal Wellington.
Habitat
Coastal to montane (0-800 m.a.s.l.), cliffs and escarpments, amongst rocky faces and outcrops, in damp places.
