Wavy Hairgrass

Avenella flexuosa

Wavy Hairgrass (Avenella flexuosa) is a species of flowering plant native to Europe, Asia, and North America. It grows in a wide range of habitats, including meadows, ditches, the margins of woods and ponds, and sandy or gravely soils. The stems of this plant are dark green and form an upright habit up to 50 cm high, with wavy, slightly flattened leaves. The flowers are small and reddish-purple, forming panicles on the top of the stem. It is an excellent source of forage for wildlife, and makes a good choice for naturalizing areas of the garden.

watering

Wavy Hairgrass (Avenella flexuosa) should be watered weekly in the spring and summer and monthly in the autumn and winter. In the spring and summer, water thoroughly so that the soil is moist but not soggy. In the autumn and winter, water only enough to keep the soil slightly moist. Avoid over-watering as this can damage the grass.

sunlight

Wavy Hairgrass (Avenella flexuosa) prefers bright light. The plant should be placed in an area where it will receive at least 4 hours of direct sunlight per day, preferably in the morning or late afternoon when sunlight intensity is lower. For best results, it should receive indirect sunlight for the remaining daylight hours. This will keep it looking full and vibrant, while avoiding scorching of the delicate leaves.

pruning

Wavy hairgrass (Avenella flexuosa) should be pruned lightly once a year, around early spring or late fall, before the new growth begins. Pruning should be restricted to removing dead or damaged blades. Due to its shallow, fibrous root system, cut too much or too frequently and you will not only deplete the grass’s energy reserves, but you'll also prevent new, healthy blades from being formed.
