Plant facts:

A low-growing, tufted native sedge that forms dense, bright green patches. It has a grass-like appearance and is well suited to open, dry environments. Tough and adaptable, it performs well across a wide range of conditions and is commonly used in naturalistic plantings.

Natural habitat:

Found from coastal to montane regions in open grasslands, gumland scrub, clay pans, rocky areas, talus slopes, and other sparsely vegetated sites.

Growing environment:

Sun, Wind, Drought & Free draining tolerant.

Endemic distribution:

New Zealand (North and South Islands). Also found in Australia, New Guinea, Lord Howe Island, and Norfolk Island.

Height:

Typically very low-growing (10–20 mm culms, with foliage forming dense mats above this)

Flowering:

August – December

Fruiting:

October – May

Uses:

• Ground cover
• Lawn alternative
• Erosion control
• Native landscaping

Appearance:

Growth habit:
Forms tight, low-growing clumps with short underground rhizomes, creating dense, carpet-like patches.

Leaves:
Fine, grass-like leaves (1.5–3 mm wide), typically longer than the flowering stems. Leaves are slightly curved (recurved) and have very finely rough margins.

Flowers:
Small, pale green spikes clustered near the base of the plant. The terminal spike is male, while the lower spikes are female.

Fruit:
Produces small, enclosed seeds (nuts) within sac-like structures that aid in dispersal by wind and animals.

How to grow:

Easily grown from fresh seed or by division. Prefers full sun and well-drained soil but tolerates a wide range of conditions, except permanently waterlogged sites. Can naturalise in suitable environments but is not considered invasive.
