Common name(s): Toetoe, toetoe-kākaho, toetoe-mokoro, toetoe-rākau

About:
A large wetland toetoe endemic to the North Island of New Zealand. Distinguished by its ivory-white waxy leaf sheaths, stout upright flowering plumes, and strong association with swamps, wetlands, and harakeke-dominated habitats.

Natural habitat:
Occurs naturally in freshwater wetlands, swamps, damp valley floors, stream margins, seepages, and wet lowland areas.

Growing environment:
Full sun to partial shade, Wet soils, Frost tolerant & Wind tolerant.
Thrives in consistently moist to wet ground and tolerates seasonal flooding.

Endemic distribution:
Endemic to New Zealand.
Confined naturally to the North Island from western Waikato south to Wellington.

Height:
Approximately 2–4 m tall when flowering

Width:
Large clumping tussocks typically 2–3 m across

Flowering:
Late spring to summer
Produces large creamy-white upright plumes from November through February.

Fruiting:
Spring to autumn
Wind-dispersed seed develops from October through March.

Uses:

• Wetland restoration
• Streambank stabilisation
• Shelter planting
• Cultural weaving material
• Ornamental landscaping
• Habitat restoration

Appearance:

Growth habit:
A massive tussock-forming grass with dense upright foliage and tall rigid flowering stems.

Leaves:
Leaves are long, coarse, straw-yellow to green, sharply edged, and strongly ribbed with distinctive waxy ivory leaf bases.

Flower plumes:
Produces dense creamy-white to pale buff plumes held upright above the foliage.

Seed heads:
Large feathery seed heads persist well after flowering and disperse freely by wind.

Ecology:
An important wetland and riparian species providing erosion control, shelter, nesting habitat, and structural diversity within freshwater ecosystems.

Associated habitats:
Frequently grows with harakeke (Phormium tenax), sedges, raupō, wetland shrubs, and riparian forest margins.

How to grow:
Best grown in full sun or light shade in permanently moist or wet soils. Very hardy once established and tolerant of flooding, wind, moderate drought, and coastal conditions.

Propagation:
Easily propagated from fresh seed or by division of established tussocks. Fresh seed germinates rapidly when surface sown and kept moist.

Cultural significance:
Traditionally one of the most important weaving and construction grasses used by Māori. The flowering stems (kākaho) were widely used for wall linings, roof panels, tukutuku frameworks, arrows, pipes, kite frames, and weaving materials.

Garden value:
A spectacular large-scale native grass ideal for wetland plantings, naturalistic landscapes, erosion control projects, and bold native garden designs. Particularly valuable for authentic New Zealand ecological restoration and cultural landscapes.
