Matgrass is a hardy, perennial grass that forms dense, low mats in acidic, nutrient poor soils. It is a common sight in heathlands and mountain pastures across Europe. You will find it thrives where other grasses struggle to gain a foothold.

Care
This grass prefers cool, damp conditions and does not require much attention once established. Watch for signs of drying out during extreme heat, though it is quite drought tolerant in its native range. Keep the soil acidic to ensure it stays healthy.
- Watering
- Keep the soil consistently moist but never waterlogged.
- Feeding
- It rarely needs fertilizer as it is adapted to poor soil conditions.
- Pruning
- Trim back dead foliage in early spring to encourage fresh growth.
- Repotting
- Repot only when the root system has completely filled the container.
- Soil
- Acidic, sandy, or peaty soil
- Soil pH
- 4.0 to 6.0
- Temperature
- -30 to 25°C
- Humidity
- 60 to 90%
- Drought tolerance
- Moderate
- Lifespan
- Perennial, typically 5 to 10 years.
- Deer and rabbits
- High
Signs it needs repotting
- Roots circling the bottom of the pot.
- Reduced growth despite adequate moisture.
Safety
- People
- There are no reports of significant toxicity to humans, though it is not a food source.
- Children
- The sharp, stiff leaf blades can cause minor scratches to children's skin if they play in dense patches.
- Contact allergens
- The stiff, wiry leaves can cause minor skin irritation if handled roughly.
- Airborne allergens
- Like many grasses, it produces wind-borne pollen that may trigger hay fever in sensitive individuals.
- Edibility
- This grass is not considered edible for humans and is generally avoided by grazing livestock due to its tough, wiry texture.
How to identify it
- Dense, tufted perennial grass clumps
- Stiff, bristle like grey green leaves
- One sided, slender flower spikes
- Forms low, mat like colonies
- Height
- 0.15 to 0.3m
- Spread
- 0.1 to 0.2m
- Leaves
- green, grey-green, deciduous
- Flowers
- purple, yellow, 0.5 to 1cm
Problems to watch for
- Rust fungus · Orange or brown pustules may appear on leaves during periods of high humidity.

Growing it
- Propagation
- division, seed
- When to plant
- spring, autumn
- Overwintering
- The plant is fully hardy and requires no special protection. Simply leave the foliage in place to protect the crown from winter moisture.
- In containers
- It is not well-suited for containers due to its specific need for acidic, nutrient-poor soil and its tendency to form wide mats.
Division
- 1. Dig up a mature clump in early spring.
- 2. Gently tease the root mass apart into smaller sections.
- 3. Replant the sections immediately into acidic, moist soil.

Grows well with
- Heath bedstraw · They naturally occur together in acidic heathland habitats.
- Tormentil · This plant shares the same preference for nutrient-poor, acidic soils.
Similar species
- Purple moor grass · It also prefers acidic, damp soils but grows much larger.
Science

- Native range
- Europe, western Asia, and North Africa. Introduced in parts of North America.
- Conservation
- It is a common and widespread species in its native range and is not currently of conservation concern.
It survives in harsh, nutrient-poor environments by forming dense mats that conserve moisture and outcompete other species for limited resources.

Questions people ask
- Will this grass grow in my garden?
- It prefers acidic, damp, and nutrient-poor soil, so it may struggle in typical fertile garden beds.
- Does it need to be mowed?
- No, it is a slow-growing, low-stature grass that does not require regular mowing.
Where the name comes from
The genus name Nardus comes from the Greek word for a fragrant ointment, though this plant lacks that scent. The specific epithet stricta refers to the stiff, upright growth habit of the leaves.
Good to know
- It is commonly known as mat grass because it forms dense, tough mats that exclude other plants.
- The plant is highly resistant to grazing, which allows it to dominate overgrazed pastures.
- It thrives in acidic, waterlogged soils where few other grasses can survive.
