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, North-West Nelson from Mt Burnett (Whakamarama Range) to the Pikikirunga and Arthur Ranges inthe east
Montane to alpine (300 - 1400 m a.s.l.). A calcicole confined to limestone, marble, dolomite-limestone, dolomite-marble and dolomite rock outcrops and boulderfalls. Usually found in open sites or in sparsely vegetated situations. Sometimes in shrubland. Often around cave entrances and sink holes (tomo).
Erect, glabrous, summer-green, glaucous, perennial herb up to 0.9 x 1.0 m. Rootstock woody. Branches arising from base, dying back to base in winter with new seasons growth arising from numerous shoots at or just beneath soil surface. Stems not or only sparingly branched, 0.15-1 m tall. Lower stem leaves shortly petiolate, petiole broad and tapering; lamina 200-300 mm long, glaucous above, paler beneath, oblanceolate, obovate, elliptic to almost rhomboid, apex obtuse to acute, base attenuate, margins serrate to sinuate-serrate, rarely sub-entire. Mid stem leaves similar up to 900 mm long, narrowing to a broad petiole or subamplexicaul to amplexicaul. Upper stem leaves much narrower and smaller, bases auriculate, auricles deeply lacerate or entire. Inflorescences Unit terminal, of (1-)10(-15) capitula arranged corymbosely, overtopping leaves. Involucral bracts 5 mm long, linear. Ray florets 10-16, ligules 2-6 x 2-2.5 mm, bright yellow, linear ovate, ovate to oblong. Disc 5-8 mm diameter. Cypsela 2.5-3.5 x 0.5-0.7 mm, brown, dark brown to black-brown, narrowly elliptic to narrowly oblong-elliptic, slightly narrowed to or constricted below apex, base cuneate. Ribs broad and rounded; grooves deep, u-shaped; hairs retrorse in 1-6 rows, confined to grooves. Pappus 4.5-6.5 mm long, white.
Morphologically S. glaucophyllus is most likely to be confused with the type form of S. banksii Hook.f. which occupies similar habitats in the North Island, has similar glaucous to glaucescent leaves and flowers. However, S. banksii is in the North Island only, has smaller seeds (up to 3.0 x 0.6 cf. 3.5 0.7 mm) and a different chromosome number (2n = 60).
November - January
January - April
Easy from fresh seed and semi-hardwood cuttings. Does best in a pot in soil enriched with lime. Inclined to be short-lived.
Not threatened. However, a very local plant known from very few places, and common at none.
Dolomite and Marble
senecio: From the Latin senex ‘old man’ (probably referring to the bearded seeds)
glaucophyllus: Blue or greyish/bluish leaves; having bloom on the leaves
Where To Buy
Not commercially available
A very distinctive plant perhaps closely allied to S. banksii s.s. The Senecio glaucophyllus complex, including S. matatini, was revised by Liew et al. 2021. For more information on the group please refer to this paper (reference below)
