Common name(s): Matthew’s Fescue, Blue Fescue

About:
Matthew’s Fescue is an elegant endemic New Zealand tussock grass forming neat clumps of fine blue-green to glaucous foliage. It produces graceful, open flowering stems well above the foliage during spring and summer, adding movement and texture to alpine and native landscapes. Hardy and adaptable, it is one of New Zealand’s finest ornamental native tussocks.

Natural habitat:
Occurs naturally in montane to alpine tussock grasslands, often growing on well-drained slopes and open high-country environments.

Growing environment:
Sun, Frost, Wind & Free draining tolerant.

Endemic distribution:
Endemic to New Zealand.

Found throughout much of the South Island, occurring east and west of the Main Divide from the Waiau River south to Fiordland, with occasional populations in Marlborough.

Height:
40 cm–1 m

Width:
30–60 cm

Flowering:
October – December

Produces airy, open panicles of straw-coloured to lightly purple-tinged flower spikelets with yellow to purple-tinged anthers.

Fruiting:
November – March

Produces fine grass seed dispersed naturally by wind, water and attachment to animals.

Uses:
• Feature tussock
• Native gardens
• Rock gardens
• Mass landscape planting
• Meadow plantings
• Erosion control
• Alpine restoration
• Texture planting

Appearance:

Growth habit:
A dense tuft-forming perennial tussock with upright foliage and elegant flowering stems that rise well above the leaves.

Leaves:
Fine, narrow blue-green to silvery-glaucous leaves with a softly textured appearance. The foliage forms compact rounded tussocks and remains attractive throughout the year.

Flowers:
Large, open and gracefully spreading flower panicles are held high above the foliage, creating a light, airy appearance. Spikelets are straw-coloured, sometimes flushed bronze or purple.

Fruit:
Small grass seeds mature through summer and are dispersed by wind and animals.

Ecology:
An important component of New Zealand’s alpine and subalpine grasslands, providing ground cover, stabilising soils and contributing to high-country biodiversity.

Associated habitats:
Montane grasslands, alpine herbfields, tussock landscapes, rocky slopes and open high-country environments.

How to grow:
Grow in full sun with free-draining soil. It thrives in exposed, cool climates and tolerates frost, wind and dry conditions once established. Avoid humid or poorly drained sites where growth may decline.

Propagation:
Easily propagated from fresh seed or by division of established clumps. Division every few years helps rejuvenate older plants and maintain vigorous growth.

Cultural use:
As one of New Zealand’s endemic alpine grasses, Matthew’s Fescue contributes to the distinctive character of South Island high-country landscapes and is increasingly valued in ecological restoration and native landscape design.

Garden value:
Matthew’s Fescue is an exceptional ornamental tussock, admired for its fine blue-grey foliage, graceful flowering stems and year-round architectural form. It is ideal for rock gardens, gravel gardens, modern native landscapes and large-scale restoration projects where texture, movement and resilience are desired.
