Current conservation status
The conservation 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). 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.

Endemic. South Island, Marlborough , Kaikoura Coast from the Flaxbourne River to Clarence River mouth and inland on the Chalk Range. Also known from the Pikikiruna Range at Gorge Creek (north-west Nelson)
Confined to calcareous rocks, especially fine grained limestone. Coastal to montane (0 - 800 m a.s.l.), and mainly restricted to gorges and steep cliffs. Less commonly found growing in boulder falls and on sparsely vegetated terraces.
Perennial, erect or spreading subshrub up ot 300 mm tall. Tap root fleshy, white, soon developing rhizomes. Stems arising from base, initally brownish-white, 2-3 mm diameter, soon purple-red to purple, glabrous, branching at the top into 2 or more almost naked scapes. Leaves crowded on stems, 10 x 1 to 50 x 3 mm, dark green, linear, glabrous, margins entire or distantly, finely toothed, sometimes recurved. Scapes 100-150 mm long, simple or branched again, bearing a few, distant, narrow linear bracts 5-15 mm long. Inflorescence, terminal, pedunculate. Calyx glabrous, 4-5 x 1 mm, linear-triangular. Flowers pale blue to pale blue-lilac with white zoning and deeper blue or violet veins, or completely white; corolla 20-40 mm diameter, deeply campnaulate with tube 7 x 5 to 9 x 6 mm, lobes spreading, 10 x 6 - 20 x 8 mm, ovate-lanceolate. Anthers linear, 4 mm long, style equalling corolla tube, stigma usually 2-lobed. Capsule glabrous, 6 x 4 to 12 x 6 mm long, domed obconic. Seeds 0.5 mm long.
None. The distinctive erect subshrub habit, and branches bearing numerous, crowded, dark green linear leaves set this species well apart from any of the other New Zealand Wahlenbergia Roth.
December - April
January - April
Easily grown from fresh seed. Does best in full sun, in a free draining, calcareous soil. Excellent in a rockery. A beautiful plant which deserves to be more widely cultivated than it is.
Abundant within its Marlborough range but rather uncommon in north-west Nelson. Browse dby animals where it is accessible but otherwise very common and not unduly threatened. This specie sis listed mainly because it is a narrow-range endemic.
wahlenbergia: Named in honour of Wahlenberg, a Swedish botanist and author of A Botany of Lapland.
