Mingimingi

Coprosma propinqua

Not Threatened

Mingimingi is a distinctive evergreen shrub reaching 2-4 meters tall with a unique divaricating (interlaced branching) growth habit that creates an almost impenetrable thicket. This remarkable species has small, narrow leaves and produces translucent blue to white berries that are highly prized by native birds. Found throughout New Zealand in shrublands, forest margins, and exposed sites, it's renowned for forming dense protective habitat that provides crucial shelter for many native species. The intricate branching pattern and unusual berries make it one of the most ecologically valuable among New Zealand's native shrubs

Seasonal Care Calendar

Spring

  • New small leaves emerge on intricate branching
  • Tiny inconspicuous flowers appear on female plants
  • Good time for planting new wildlife habitat areas
  • Begin watering schedule for establishment

Summer

  • Dense divaricating growth provides maximum shelter
  • Wind pollination occurs between plants
  • Young berries begin developing on female plants
  • Drought tolerance becomes apparent in established plants

Autumn

  • Translucent blue to white berries ripen creating spectacular displays
  • Peak bird activity as native species seek out the prized berries
  • Good time for planting before winter
  • Collect unique translucent berries for propagation

Winter

  • Berries persist providing crucial winter food for birds
  • Dense branching provides essential winter shelter
  • Excellent cold tolerance with no winter protection needed
  • Best time for structural pruning if needed

When to Prune and How Much

When to Prune and How Much Overview

Mingimingi's divaricating habit is best left natural, but can be managed:

  • Remove dead, diseased, or damaged branches any time
  • Can be lightly trimmed to control size if necessary
  • Avoid heavy pruning as it destroys the natural protective structure
  • Late winter to early spring best for any pruning work
  • Consider wildlife impact before pruning dense habitat areas

Use sharp, clean tools and work carefully around the intricate branching. The natural form provides maximum wildlife value.

Planting Guide

When to Plant

Plant Mingimingi from spring through autumn when soil conditions allow. This hardy species establishes well even in challenging conditions.

Site Selection

Choose a site with:

  • Full sun to partial shade (adaptable to most conditions)
  • Any reasonably drained soil type
  • Space for mature size and natural spreading habit (4m tall, 3m spread)
  • Consider positioning for wildlife habitat benefits

Planting Procedure

  1. Dig hole twice as wide and same depth as root ball
  2. Soil improvement usually not necessary due to adaptability
  3. Position plant at same level as in container
  4. Backfill with existing soil, watering to settle
  5. Create watering basin for establishment
  6. Water moderately after planting
  7. Apply organic mulch layer around base

Initial Care

Provide regular watering during first 1-2 years until established. Mingimingi becomes very self-sufficient once the divaricating structure is established.

Propagation Methods

From Seed

Mingimingi propagates well from the distinctive translucent berries:

  1. Collect ripe translucent blue to white berries from female plants
  2. Remove pulp carefully to extract small seeds
  3. Sow fresh seeds immediately in seed mix at 3mm depth
  4. Keep moist but not waterlogged
  5. Germination occurs within 6-12 weeks
  6. Transplant seedlings when 10-15cm tall and divaricating habit begins

Remember to grow both male and female plants for berry production and wildlife value.

From Cuttings

Vegetative propagation is successful:

  1. Take hardwood cuttings from healthy divaricating growth
  2. Use rooting hormone for better success rates
  3. Use well-drained cutting mix
  4. Rooting typically occurs within 8-12 weeks
  5. Good success rates (60-80%)

Natural Regeneration

Mingimingi often establishes naturally through bird dispersal:

  • Birds readily consume and disperse the translucent berries
  • Self-seeds moderately in suitable shrubland habitats
  • Volunteer seedlings can be transplanted to extend habitat areas
  • Natural establishment helps create authentic shrubland communities

Cultural History

Mingimingi holds important cultural significance as one of New Zealand's most distinctive and ecologically valuable native shrubs:

Traditional Māori Uses

  • Name Origin: "Mingimingi" refers to the tangled, interlaced branching pattern
  • Protective Barrier: Dense thickets used as natural fencing around settlements
  • Shelter: Impenetrable growth provided emergency shelter and protection
  • Wildlife Management: Dense habitat supported bird populations for traditional hunting

Cultural Recognition

  • Divaricating growth habit made it unique among native plants
  • Associated with boundary marking and defensive purposes
  • Traditional knowledge recognized its supreme wildlife value
  • Translucent berries noted as special food for native birds
  • Featured in traditional ecological knowledge about shrubland succession

European Settlement Era

  • Early settlers noted its impenetrable nature and wildlife value
  • Sometimes managed as natural stock-proof barriers on farms
  • Recognized as excellent habitat for native birds
  • Studied by botanists for its unique divaricating growth form

Modern Conservation Role

Today, Mingimingi is recognized as a keystone species in native habitat restoration. Its unique ability to provide dense, protective habitat makes it essential for supporting populations of small native birds and creating authentic shrubland ecosystems.

Pests & Diseases

Scale Insects

  • Damage: Various scale species may infest the small leaves
  • Symptoms: Yellowing leaves, sticky honeydew
  • Management: Usually controlled naturally by beneficial insects in dense growth

Sooty Mould

  • Cause: Fungus growing on honeydew from scale insects
  • Symptoms: Black coating on leaves and branches
  • Management: Usually self-limiting; ensure good air circulation

Browsing Damage

  • Stock: Young plants may be browsed by livestock
  • Possums: May browse on berries and young shoots
  • Management: Protect young plants until divaricating structure develops

Root Rot

  • Cause: Waterlogged conditions in poorly drained soils
  • Symptoms: Branch dieback, yellowing foliage
  • Management: Ensure good drainage; avoid overwatering

Mingimingi's dense, intricate structure and hardy nature make it resistant to most pest and disease problems. The divaricating habit provides natural protection once established.

Bonus Tip

Bonus Tip Overview

Plant Mingimingi where you want to create serious wildlife habitat - the dense divaricating branches provide unparalleled protection for small native birds, while the translucent berries are among the most sought-after by species like bellbirds and tui. Allow it to develop its natural impenetrable form rather than pruning, and position where you can observe the constant bird activity it attracts. The unique architecture makes it a living sculpture that changes with the seasons.

Details

This plant has cultural associations in Aotearoa and is valued in restoration and gardens for ecological services; use eco‑sourced stock near natural areas.

Coprosma species held important cultural significance for Māori, with the orange berries of larger species like karamū (C. robusta) eaten by children as a traditional food source. Kanono (C. grandifolia) was particularly valued for its bark, which provided a vibrant orange dye used in traditional crafts and ceremonial items. These versatile shrubs were integrated into daily life, providing both sustenance and materials for cultural practices.
