Care

Exposure

Install this grass in full sun to obtain the most beautiful bluish foliage colors. It tolerates partial shade but prefers bright locations. Avoid overly shaded areas which weaken the plant.

Soil and drainage

Helictochloa versicolor thrives in well-drained soils, even chalky or poor ones. It dislikes stagnant moisture: improve drainage if your soil is heavy or clayey. This grass adapts well to dry and rocky terrain.

Watering

Once established, this grass is very economical with water. Water regularly for the first few weeks after planting to encourage rooting. After that, watering is only necessary during prolonged droughts.

Pruning and maintenance

Cut back the dried foliage to ground level in late winter (February-March) or early spring. Use a metal comb or trimmer to remove dead parts. This operation rejuvenates the clump and encourages spring growth.

Fertilization

No fertilizer application is really necessary. If the soil is very poor, a light application of compost in early spring is sufficient. Avoid excess nitrogen which weakens resistance and spoils the appearance of the foliage.

Health and prevention

This grass is naturally resistant to diseases and pests. In case of excessive moisture, root rot may appear: improve drainage. Otherwise, no specific treatment is generally required.

Did you know?

Helictochloa versicolor owes its scientific name to the spectacular variability of its colors: "versicolor" literally means "of many colors". Its finely bluish foliage turns reddish or purple depending on the season, light and growing conditions, making it a particularly prized ornamental grass in mountain gardens where it rivals asters and saxifrages in beauty.

Where to buy it

Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
