Clematis paniculata (in Māori puawānanga[2] or puapua) is a species of flowering plant in the buttercup family Ranunculaceae.

[3] Puapua on the other hand comes from reduplication of the Polynesian term pua referring to either Fagraea berteroana, Guettarda speciosa or Gardenia taitensis.

[11] Clematis paniculata prefers soils that are damp but not overly soaking and if the roots become dried out the plant will not survive.

[12] In the northern North Island, it will most likely be found in granular soil which is a volcanic material that has been derived from substantial weathering.

[12] C. paniculata prefers sunny areas as the vine will grow up other trees to be able to reach the sunlight.

[17] It is only found to infect C. paniculata in Dunedin and the centre of the North Island[8] The rust produces colourless teleutospore on the host.

One way is the virions can be kept in an infectious state for the amount of time it takes for the aphid to go and give it to a plant that has not been infected yet.

[19] This is what makes Cucumber mosaic virus so detrimental to crops, as the aphid can quickly and easily spread it from one plant to another.

[19] Clematis paniculata or known in Te Reo as Puawananga is very important to the Māori community as it has great cultural significance.

[20] They also use the flowering of the plant as an indicator as that the season of spring has started and that the eels have started to migrate up the rivers to spawn therefore it was time to harvest them as this is a spring event, so the two events of the flowering and eel migrating coincided.

Females would use it for multiple things such as general blood disorders, skin eruptions, kidney troubles, haemorrhages and bleeding piles.

[23] Something unique about the Clematis paniculata is that there are no similar taxa to it in New Zealand whether it is endemic, native or an exotic species there is nothing else like the dark green colour of the leaves.

It is the only species that fit these categories in New Zealand, which is what makes it so unique and special, along with being a native plant.
