Native seed catalogue

Coprosma grandifolia Large-leaved coprosma | Kanono

This guide is based on a literature review. It compiles information from various sources. Different sources may offer varying advice and findings.

Other known names

Coprosma autumnalis, patutiketike, kawariki, manono, raurākau, kapukiore.

Propagation summary

Variations found with sowing to germination time frame. Little information on seed viability and storage. Can be grown from cuttings.

Seed propagation category

Hard.

Geographical distribution

Widespread throughout the North Island and in the northern coastal parts of the South Island. Found at forest margins or in low regenerating forest and mainly in regions of high rainfall.(1)

Reproductive system

Dioecious – can only collect seeds from female plants.(2)

Seed collection

Seeds can be dispersed by birds.(1)

Seed storage

Seeds kept dry at room temperature and humidity for 5 months had a germination rate of 8%.(1)

Seed dormancy

Dormancy between 90–120 days.(2) Seeds sown in March germinated in August.(3)

Pre-sowing treatments

The seed needs to be de-pulped (removal of seed from fruit).

Germination

100% germination after 10 weeks.(1)

Propagation techniques

Lower and slower germination when kept in the dark and in-fruit.(1) Semi-hardwood and hardwood cuttings can take 2–6 months to form roots.(3)

Research opportunities

Germination, seed storage, and vegetative propagation need further investigation.

Information about the native seed profiles

All species names are in the following order: scientific name, common name, and Māori name. Names may vary by region. We have tried to use the most common names across New Zealand.

We have sourced photos from different websites and creators. We have used the images under different licences. These include Public Domain and Creative Commons licenses. For Coprosma grandifolia, the image details are:

The basis for each seed profile is a literature review carried out by Scion. Te Uru Rākau – New Zealand Forest Service commissioned and worked on the review to produce a native seed catalogue. The full seed catalogue is on the Ministry for Primary Industries (MPI) website.
