A Respectful Guide to Identification, Ecology, and Growing Your Own

New Zealand’s native plants are taonga—treasures. They represent millions of years of evolution in isolation, creating species found nowhere else on Earth. This guide focuses on identifying common natives, understanding their ecological roles, and growing your own native garden, while respecting the deep cultural knowledge systems (rongoā Māori) that have cared for these plants for over 700 years.

Why Grow Native Plants Instead of Foraging?

Conservation: Over 30% of NZ’s indigenous plants are threatened. 82% are endemic (found nowhere else). Wild harvesting adds pressure to struggling populations.

Cultural Respect: Many natives have deep Māori significance. Growing your own respects wild populations and traditional knowledge.

Quality: You know growing conditions (organic, contaminant-free). Sustainable source you can harvest as needed.

Accessibility: Native nurseries widespread across NZ ($2-25 per plant). Many councils offer free/subsidised natives. Community planting days provide free plants.

Wild harvesting guidelines: Only with explicit permission, from abundant populations, taking <5% maximum, understanding tikanga, checking conservation status. Even then, growing your own is preferred.

Native Plant Profiles

1. Kawakawa (Piper excelsum)

Identification:

• Leaves: Heart-shaped, 5-10cm across, dark green, aromatic when crushed
• Distinctive feature: Leaves often have holes from kawakawa looper moth caterpillar (this is normal and traditionally considered a sign of potency)
• Flowers: Small greenish spikes
• Fruit: Orange berries on female plants (not all plants fruit—dioecious species)
• Growth: Shrub or small tree, 2-6m tall
• Bark: Jointed stems with swollen nodes

Where It Grows Naturally:

• Native forests throughout North Island and northern South Island
• Forest margins, clearings, regenerating bush

Ecological Role:

• Food source: Berries eaten by kererū (wood pigeon), tūī
• Insect host: Kawakawa looper moth larvae feed exclusively on leaves
• Understory plant: Provides habitat in forest understory layer
• Indicator species: Presence suggests healthy native ecosystem regenerating

Growing Kawakawa:

• Availability: Native nurseries NZ-wide — $5-20/plant depending on size
• Conditions: Shade to partial sun, moist soil, frost protection when young
• Propagation: Easy from cuttings (semi-hardwood), moderate from seed
• Care: Keep moist, mulch well, protect from strong wind

Conservation Status: Not Threatened (but local populations can be vulnerable)

2. Harakeke / NZ Flax (Phormium tenax and P. cookianum)

Identification:

• Leaves: Long, sword-shaped, growing in fan formation from base
• P. tenax (harakeke): Large, upright, blue-green leaves up to 3m, reddish base
• P. cookianum (wharariki/mountain flax): Smaller (1-2m), yellow-green, more drooping
• Flowers: Tall flower stalks (up to 4m) with tubular red, orange, or yellow flowers
• Growth: Forms large clumps, multiple fans per plant

Where It Grows Naturally:

• Throughout NZ in wetlands, swamps, stream margins
• Coastal areas (tolerates salt spray)

Ecological Role:

• Bird attraction: Flowers produce abundant nectar for tūī, bellbirds, silvereyes
• Erosion control: Extensive root systems stabilise stream banks
• Insect habitat: Provides shelter for numerous invertebrates
• Wetland indicator: Presence suggests wetland conditions or water table

Growing Harakeke:

• Availability: Garden centres, native nurseries — $5-30/plant (many cultivars)
• Conditions: Full sun to part shade, moist to wet soil, tolerates drought once established
• Propagation: Division of fans (easiest), seed
• Care: Water well first year, then very hardy, remove old flower stalks

Conservation Status: Not Threatened, though “yellow-leaf disease” (phytoplasma spread by flax planthopper) affects some populations

3. Mānuka (Leptospermum scoparium)

Identification:

• Leaves: Small (7-20mm), prickly, aromatic, with sharp pointed tip
• Flowers: White or pink, five petals, prominent stamens, dark central capsule
• Bark: Flaky, stringy, peels in strips on mature plants
• Growth: Shrub or small tree, 2-5m (occasionally to 15m)
• Similar species: Often confused with kānuka (Kunzea) but mānuka leaves are prickly to touch, kānuka soft

Where It Grows Naturally:

• Widespread throughout NZ in scrubland, regenerating forest, hillsides
• Tolerates poor soils, disturbed sites

Ecological Role:

• Pioneer species: First to colonise disturbed ground, stabilises soil, creates conditions for other natives
• Insect food: Flowers provide nectar/pollen for native bees, beetles, flies
• Shelter: Dense growth provides habitat for small birds
• Succession: Eventually shaded out by taller trees as forest matures

Growing Mānuka:

• Availability: Very common in nurseries — $2-8/small plant, up to $20/larger specimens or cultivars

• Several species: Different species throughout NZ

Where It Grows Naturally:

• Throughout NZ in forest margins, stream banks, coastal areas
• Different species have different distributions (North vs South Island)

Ecological Role:

• Nitrogen fixation: Legume family—roots harbour nitrogen-fixing bacteria (Rhizobium), enriching soil
• Bird food: Nectar crucial for tūī, bellbirds, kākā in early spring (when other food scarce)
• Insect host: Kōwhai moth larvae feed on leaves
• Succession: Long-lived, provides structure in mature native forest

Growing Kōwhai:

• Fronds: Large, feathery, dark green above, distinctive silver-white undersides
• Trunk: Slender, rough, brown, covered with hexagonal leaf base scars
• Growth: Tree fern, up to 10m tall (trunk grows very slowly)
• Distinctive: Turn fronds over—silver underside is unmistakable

Where It Grows Naturally:

• Throughout NZ in drier lowland forests
• More common North Island, widespread in suitable South Island habitats

Ecological Role:

• Sub-canopy: Forms middle layer in native forests
• Epiphyte habitat: Trunk hosts mosses, lichens, small ferns

Sustainable Wild Harvesting Protocols (If You Must)

We emphasise growing your own, but if you’re in a position where wild harvesting is appropriate:

Before harvesting wild natives (if you must):

1. Check Conservation Status:

• Visit nzpcn.org.nz
• Search for your specific plant
• Check threat classification
• Never harvest Threatened or At Risk species

2. Confirm Legal Permission:

• Private land: Get explicit landowner permission
• DOC land: Check specific area regulations (doc.govt.nz)
• Council land: Usually prohibited (check bylaws)
• Māori land: Requires permission from tangata whenua

3. Assess Population Health:

• Is this a large, healthy population?
• Are there seedlings/juveniles present? (population recruiting)
• Are there signs of stress (dieback, disease, pest damage)?
• If population is small or stressed, don’t harvest

While harvesting:

The 5% Rule (Actually 2-3% for Natives):

• From any population, harvest maximum 5% (for natives, aim for 2-3%)
• Example: 100 kawakawa plants = harvest from 2-3 plants maximum
• Spread harvest across area, don’t strip one plant

Selective Harvest:

• Take from healthy, vigorous plants
• Leave the largest, healthiest plants (breeding stock)
• Don’t take from small or young plants
• Avoid plants in flower/fruit (let them reproduce)

Minimal Impact Techniques:

• Clean cuts with sharp tools (not ripping/tearing)
• Harvest outer leaves, never growing tips
• For kawakawa: 2-3 leaves per plant maximum
• For harakeke: Never centre leaves, proper cultural cutting protocols
• For tree ferns: Never growing tip (kills plant)

Leave More Than You Take:

• If in doubt, take less
• Consider just taking a photo instead
• Maybe this population shouldn’t be harvested at all

After:

Give Back:

• Remove invasive weeds nearby
• Pick up rubbish
• Spread mulch around plants
• Consider planting additional natives

Acknowledgment:

• Many people use karakia (prayer/acknowledgment)
• Or simple gratitude
• Recognise the plant’s gift

Document:

• Record location, date, amount taken
• Monitor population over time
• If population declines, stop harvesting

Final Thoughts

New Zealand’s native plants are extraordinary. Eighty-two percent found nowhere else on Earth. They’ve evolved here for millions of years, creating unique adaptations, relationships, and ecosystems.

When you grow natives:

• You participate in conservation
• You support the birds, insects, and other creatures that depend on them
• You build a living connection to this place
• You honour the knowledge systems (rongoā Māori) that have cared for these plants

Start small:

• One kawakawa plant
• A mānuka by the fence
• A harakeke by the tap

Learn deeply:

• Observe through seasons
• Notice which birds visit
• Watch insects on flowers
• Feel the connection grow

Respect boundaries:

• Acknowledge rongoā Māori knowledge exists beyond this guide
• Seek proper teaching for medicinal use
• Appreciate without appropriating
• Grow rather than take from the wild

These plants are taonga. Treat them as such.
