Current conservation status
The threat classification status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Endemic. New Zealand: North and South Islands from East Cape and Taranaki south to the Marlborough Sounds. Most common on the shores of Cook Strait.
Mostly coastal (rarely inland). On rocks, cliffs, grassy places and in open scrub
Radicate, perennial herb. Stems 100-500 mm long, 1-2 mm thick, decumbent or ascending or stiffly erect. Mature leaves and bracts pale-green, alternate, sessile, variable, usually obovate-spathulate to oblanceolate on lower stem, grading to linear-lanceolate in upper stem, 8 × 2 to 30 × 10 mm; margins flat and distantly denticulate to strongly undulate, usually with scattered hairs on margins and lamina. Callus teeth 4-5 on each margin. Pedicels slender, 30-100 mm long. Flowers glabrous, 3-5-lobed, pastel lilac at anthesis, fading to off-white or pure white in different populations, 5-20 mm diameter, 4-9 mm long. Corolla rotate with shallow saucer-shaped tube, 1 × 3-4 mm; lobes spreading, 5 × 4 to 8 × 5 mm, broadly ovate, touching or overlapping in open flower. Style thickened at top, white. Calyx lobes glabrous, 1.5 × 1.0 to 3.0 × 1.5 mm, triangular; capsule glabrous 5-7 × 4 mm, ellipsoid to obconic, with protruding apical valves. Bud at anther dehiscence short and rounded. Self-fertile. Seeds 0.5 mm long.
Recognised by the preference for coastal habitats; alternate pale green leaves; pale-lilac flowers at anthesis, which open to off-white, or completely white flowers; rotate corolla with shallow saucer-shaped tube, and with the broadly ovate lobes overlapping in the open flower resulting in a compact appearance
November - April
December - May
Seeds, tip cuttings, rootstock transplants. Easily grown in a well drained, sunny situation. Often freely naturalises in gardens and can become weedy.
wahlenbergia: Named in honour of Wahlenberg, a Swedish botanist and author of A Botany of Lapland.
