Detailed description
Vigorous vine, shoots densely hairy with large persistent stipules. Leaves 3-lobed up to 14 cm long, densely tomentose beneath, at least some hairs above. Flowers are pink with long hypanthium (up to 9 cm) and short petals. Fruit up to about 10 cm long, obovoid, green ripening to orange-yellow and containing edible orange pulp with small black seed.
Similar taxa
Can be distinguished from P. tarminiana by the large persistent stipules, and the long hypanthium on the flower. P. mixta is also similar, but has salmon-pink flowers and a pubescent hypanthium. From var. azuayensis (q.v.) it is distinguished by having ‘leaves moderately to densely pubescent on upper surface’ (Heenan & Sykes 2003); var. azuayensis has ‘leaves glabrous to glabrate on upper surface’ (ibid.)
Habitat
Terrestrial. Typically found in shrublands, forest margins, roadsides, wastelands, farm and orchard hedges and domestic gardens. Prefers light gaps on fertile soil, In cooler areas regular frosts and occasional snowfalls appear to limit the plants growth

Tolerances
The plant is intolerant to deep shade and reprouts after grazing and physical damage. Requires medium soil fertility.
Life cycle and dispersal
Perennial. Few seedlings are present owing to the parent plants combinations of low germination levels (around 25%), high seedling mortality and shading (Buxton 1994). Reproduces from seed and can grow from stem fragments.Moderate seed numbers are produced by the plant. Seed accumulates in the soil seed bank over time, ensuring continuous germination (Williams & Buxton 1995). The fruit is eaten by pigs, possums, kiore, ship rats, Norway rats, and many birds, however it is not known whether the seed remains viable after consumption.

National Pest Plant Accord species
This plant is listed in the 2020 National Pest Plant Accord. The National Pest Plant Accord (NPPA) is an agreement to prevent the sale and/or distribution of specified pest plants where either formal or casual horticultural trade is the most significant way of spreading the plant in New Zealand. For up to date information and an electronic copy of the 2020 Pest Plant Accord manual (including plant information and images) visit the MPI website.
Environmental Weed (2024)
This plant is named in a list of 386 environmental weeds in New Zealand 2024 prepared by DOC. 759 candidate species were considered for inclusion on this new comprehensive list of environmental weeds in New Zealand. The species considered were drawn from published lists of weed species, lists of plants that must be reported or managed by law if observed, existing national and regional programmes and agreements for pest management, and species already managed by the Department of Conservation (DOC). Candidate species were then assessed to see if they were fully naturalised and whether they have more than minor impacts in natural ecosystems. Read the full report here.
NVS code
