The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

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. 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.

Fleshy shrub to 4m tall bearing dark green thin wide leaves that are divided into 1-3 large sharp lobes and with large purpleish ruffled flowers that have a projecting yellow centre. Leaves 10-80cm long by 4-6cm wide. Flowers dished, up to 50cm wide. Fruit yellow or orange, 23-30mm long. POISONOUS.
Indigenous. North, South, Stewart and Chatham Islands. Widespread from the Hauraki Gulf Islands and Auckland south. In the northern part of its range actively spreading northwards caused it would seem through establishment through bird dispersal of fruit from garden plantings. Also present in south eastern Australia and Tasmania. Naturalised in parts of China and Russia.
Coastal to montane (0-400 m a.s.l.). usually in disturbed successional habitats, in shrublands, gullies, alongside riversides, on forested margins and in reverting pasture. Often appears following fires. A common urban weed in many parts of the country.
Erect to spreading, glabrous, soft-wooded shrub up to 4 x 3 m. Stems initially somewhat fleshy, purple-green, dark green to dark purple coloured, maturing with fine, firm, grey chartaceous bark, rather brittle. Leaves in stout petioles up to 50 mm long; lamina 100-800 x 40-60 mm, sometimes even larger, very dark green to purple-green, entire or pinnatisect, (then with 1-4(-6) pairs of lobes almost cut to midrib) on the same plant; lobes up to 50 x 20 mm, lanceolate to linear-lanceolate, or more or less elliptic; base decurrent on petiole; apex obtuse to acuminate. Flowers in 2-10-many-flowered cymes, peduncles up to 20 mm long at anthesis, decurved, slender but robust; pedicels pendent at fruiting. Calyx 5-8 mm long, accrescent; lobes broadly ovate-triangular, mucronate, much < tube. Corolla 50 mm diameter, rotate, violet or white, lobes very borad, margins frilled or ruffled, apices emarginate. Anthes 3-4 mm long. Berry 23-30 mm long, yellow or orange when ripe, fleshy, ovoid, ellipsoid, pendent, stoen cells obvious and frequent similar or shape to seeds. Seeds 2.2-2.5 mm diameter, obovoid though somewhat asymetric.
Often confused with the now much less common S. aviculare G.Forst., which in its typical state has narrower leaves which are less frequently pinnatifid, usually much narrower 10-40 mm diameter) with campanulate-rotate flowers with narrower acute tipped lobes, without distinctly frilled (ruffled), smaller seeds (1-2 mm cf 2-3 mm) and a different chromosome number (2n = 46 cf 2n = 92). S. lacinatum differs from S. aviculare f. latifolium (G.T.S.Baylis) G.T.S.Baylis by its broader, wider lobes with frilled/ruffled margins and an emarginate apex, and by the chromosome number (2n = 92 cf 2n = 46).
Throughout the year
Throughout the year
Easily grown from fresh seed and semi-hardwood cuttings. Tolerant of heavy shade and full sun, and dry or wet soils and cold tolerant. Extremely fast growing and can become invasive. It should also be noted that as with all poroporo the green fruits are extremely toxic.
solanum: Derivation uncertain - possibly from the Latin word sol, meaning “sun,” referring to its status as a plant of the sun. Another possibility is that the root was solare, meaning “to soothe,” or solamen, meaning “a comfort,” which would refer to the soothing effects of the plant upon ingestion.
The fruits of this species and S. aviculare G.Forst. var. aviculare yield important steroid precursors, so both are widely and commericially grown, especially in eastern Europe, Russia and China.
As with Solanum aviculare var. aviculare, the yellow or green berries are poisonous but when ripe (orange) they lose much of their toxicity. The symptoms are often delayed up to 6-12 hours and may include a fever, sweating, nausea and abdominal pain. Click on this link for more information about Poisonous native plants.
