Māori Sedge

Botanical name: Carex maorica
Synonyms: Carex fascicularis var. minor, Carex forsteri var. minor
Common name(s): Māori sedge

About:

A light green to yellow-green tufted sedge commonly found in wetlands, riparian margins and damp lowland habitats. It is a versatile and adaptable species that performs well in restoration projects and can tolerate a wider range of conditions than many wetland sedges.

Natural habitat:
Freshwater wetlands, swamp margins, stream and river banks, lake edges, damp seepages, pond margins and forest clearings.

Growing environment:
Thrives in moist to wet fertile soils but is adaptable to a range of moisture conditions. Tolerates frost, wind, coastal exposure and occasional dry periods. Grows best in full sun but will tolerate partial shade.

Endemic distribution:
Endemic to New Zealand. Found throughout much of the North and South Islands, though uncommon in parts of the eastern North Island and absent from Fiordland and Southland.

Height:
400–700 mm tall

Width:
Forms dense clumps up to 600 mm wide

Flowering:
October – December

Fruiting:
November – May

Uses:

• Wetland restoration
• Riparian planting
• Stream bank stabilisation
• Biodiversity enhancement
• Revegetation projects
• Pond and lake margins
• Native garden planting

Appearance:

Growth habit:
Tuft-forming sedge with upright to arching foliage and clustered seed heads.

Leaves:
Light green to yellow-green, 2–7 mm wide, often exceeding the flowering stems. Leaves have distinctive cross-veinlets and a softly arching habit.

Flowers:
Male and female spikes are clustered together near the top of the stem, creating a compact flowering head. Female spikes are often larger than the terminal male spike.

Fruit:
Produces pale green to light brown strongly veined utricles that spread outward when mature, containing small light brown seeds.

Ecology:
An important wetland and riparian species that contributes to habitat diversity and bank stability. Seeds are dispersed by wind and animals.

Associated habitats:
Freshwater wetlands, swamps, seepages, stream margins, lake edges, wet forest clearings and riparian corridors.

How to grow:
Easy to grow from fresh seed or division. Plant in moist to wet soil in full sun or partial shade. Although naturally a wetland species, it adapts well to a range of garden conditions provided it does not dry out for extended periods.

Propagation:
Readily propagated from fresh seed and by division of established clumps.

Cultural use:
Part of New Zealand’s indigenous wetland flora and an important species in traditional wetland ecosystems throughout much of the country.

Garden value:
A useful and attractive native sedge valued for its bright foliage, adaptability and suitability for ecological restoration. Excellent for wetlands, rain gardens, riparian plantings and naturalistic native landscapes.
