Alpine hairgrass: complete guide

Overview

Alpine hairgrass (Deschampsia media) is an elegant, evergreen ornamental grass native to the Alps and mountainous regions of southern Europe. This graceful plant is known for its delicate, purplish-tinged panicles that appear in July and August.

The plant forms thin, compact clumps of fine green foliage. It grows slowly and remains compact, making it ideal for small spaces, rock gardens and alpine plant combinations. Alpine hairgrass is frost-hardy and low-maintenance.

Appearance and bloom

Alpine hairgrass forms an elegant, compact-growing grass clump. The leaves are very fine and setaceous (thread-like), dark green in color. The plant reaches only 30-40 centimeters in height.

The panicles are exceptionally delicate and fine, with a purplish to grayish tint. They appear on thin, elegant stems that tower above the leaf mass. The panicles are very light and wave elegantly in the breeze.

Blooming occurs from July to September. The panicles remain interesting for a long time and dry beautifully.

Ideal location

Alpine hairgrass grows best in a full sun to light shade location. A minimum of four hours of direct sunlight is needed for optimal growth. The plant also thrives in alpine mountain gardens where diffuse light is dominant.

Ensure a well-ventilated spot with good air circulation. Avoid strong wind in warm environments.

Soil

Alpine hairgrass makes very high demands on drainage. The plant grows naturally on rocks and stony mountain meadows. Ensure excellent drainage and avoid heavy, wet clay soils.

A mixture of sand, gravel and organic material in equal parts is ideal. The plant prefers slightly acidic to neutral soils. Moderately fertile soil is sufficient.

Watering

Once established, alpine hairgrass is moisture-loving and tolerates drought well. During the first two growing seasons, water regularly until well-established. Thereafter, minimal supplemental watering.

Stagnant groundwater must be absolutely avoided. The plant does not tolerate wet feet. Use only rainwater or soft water.

Pruning

Alpine hairgrass is an evergreen grass and does not undergo drastic fall pruning. In spring, dead foliage from the previous season can be removed. Remove wilted panicles if they become unsightly.

Divide old clumps every three to four years to maintain vigor.

Maintenance calendar

Spring (March-May): Remove unwanted foliage and dead leaves. Resume watering. Minimal feeding needed.

Summer (June-August): Plant blooms. Water regularly during extreme drought. Panicles appear and are striking.

Fall (September-October): Blooming ceases. Plant goes dormant. No pruning needed.

Winter (November-February): Plant is dormant. Very minimal care. Frost-hardy.

Winter hardiness

Alpine hairgrass is very frost-hardy and grows in alpine regions where temperatures reach minus 25 degrees Celsius. The plant tolerates harsh winters well as long as drainage is good.

Even in very cold regions of Europe, the plant grows without protection.

Companion plants

Alpine hairgrass combines beautifully with other alpine plants: sedums, saxifrages, alpine primulas, and dianthus. It also works well with silver-leaved plants.

In rock and gravel gardens, alpine hairgrass forms a graceful backdrop for other alpine flora.

Conclusion

Alpine hairgrass is an elegant choice for rock gardens and alpine borders. With minimal care, this plant produces season-long elegance. For rock and gravel gardens, alpine hairgrass is essential. Where to buy: Specialized nurseries have this grass available online.
