Clematis paniculata J.F.Gmel.

Scientific Name and Growth Form

Clematis paniculata J.F.Gmel. is an evergreen, woody, high-climbing vine.

Stem and Branchlet Characteristics

Its woody stem typically reaches 10 cm or more in diameter at the base, and it produces stout branchlets.

Leaf Texture and Shape

Its leaflets are leathery in texture, with visible pores and wrinkles; overall, leaves are shiny and tough in appearance, dark in colour, broadly ovate to broadly oblong in shape, with a heart-shaped to truncate base.

Leaf Surface and Margins

Leaves are sparsely hairy on the lower surface, and leaf margins may be toothed, entire, or lobed near the apex; profound lobing occurs only rarely.

Reproductive System

This species is dioecious (unisexual), producing separate male and female plants; the male and female flowers are similar in structure.

Flower Sepal Structure

Both flower types have six white sepals, which narrow toward the end, and terminate in either a rectangular or rounded tip.

Flower Sexual Dimorphism

Female flowers have smaller sepals than male flowers: females have few staminodes, while males have many.

Female Fruit Characteristics

Female plants produce hairy achenes 2–4 millimetres long, and do not bear persistent fruits.

Native and Naturalised Range

Clematis paniculata is native to New Zealand, and occurs naturally across the North, South, and Stewart Islands; it has also become naturalised on the Chatham Islands.

Habitat and Elevation

It grows throughout New Zealand in lowland and subalpine habitats, ranging from coastal areas up to elevations between 300 and 800 metres above sea level, where it occurs in tall forest or shrubland.

Flowering and Fruiting Periods

It flowers from August to November, and produces fruit from October to January.

Male Flower Reproductive Parts

Male flowers bear stamens, the male reproductive organs that produce pollen for plant reproduction.

Seed Structure and Dispersal

Its seeds are held in silky, feather-like clusters, and are easily dispersed by wind.

Seed Germination

Seed germination occurs within 2–3 months, though germination timing can be erratic.

Māori Common Name and Cultural Significance

In Te Reo Māori, this species is called Puawananga, and it holds major cultural significance for Māori communities.

Cultural Origin Story

Many Māori iwi (tribes) recognise Puawananga, alongside Whauwhapaku, as the offspring of Puanga (Rigel), the brightest star in the Orion constellation, and Rehua (Antares), the brightest star in the Scorpio constellation.

Celestial Seasonal Signal

The morning rising of these two stars signals the approach of summer.

Star Rising and Flowering Alignment

The period between the two risings, which falls between June and November, aligns with Puawananga’s flowering season.

Flowering as Ecological Indicator

Māori have used the flowering of Puawananga as an indicator that spring has begun, and that eels have started migrating upriver to spawn—an event that coincides with flowering, marking the appropriate time to harvest eels.

Traditional Decorative Uses

Māori women used Puawananga to create decorative pieces for hair wreaths and garlands.

Traditional Medical Use Restriction

There are historical records of Māori ancestors using Puawananga for medical purposes, which was only used by women.

Treated Medical Conditions

It was taken to treat a range of conditions including general blood disorders, skin eruptions, kidney troubles, haemorrhages, and bleeding piles.

Topical Medical Applications

Leaves were used to produce blisters as a counter-irritant, and sap was applied to help heal wounds.

Medical Administration Dosage

It was taken three times daily before meals.
