Deschampsia flexuosa, commonly known as wavy hair-grass, is a perennial grass species native to Europe, Asia, and North America. It often grows in forests, rocky mountain slopes, and alpine meadows.
General Appearance
The plant can grow up to 60 cm tall with a slender, wiry stem and narrow leaves that are rolled inward. The leaves can range from a light green to reddish-brown color. The flowers of the plant are borne on branched inflorescences that can grow up to 1 m in length. The flowers are typically green or purple in color and bloom from June to August.
Common Names
Deschampsia flexuosa is commonly known as wavy hair-grass. Other common names include mountain hair-grass, crinkled hair-grass, tassel grass, and hairgrass.
Uses
Deschampsia flexuosa has a variety of uses in different fields. Its dense root system helps to stabilize soil and prevent soil erosion. The plant is also used for ornamental purposes in landscaping, where its attractive appearance adds aesthetic beauty to gardens. Additionally, the plant has been used as a fodder crop for livestock in some regions.
hereLight Requirements
Deschampsia flexuosa (L.) Trin. ssp. montana (L.) A.& D. Löve thrives in partially shaded to full sun conditions. It can tolerate full shade, but it may result in thinner and leggy growth. Exposing the plant to full sun conditions can result in its leaves turning yellow and the plant drying out. Therefore, it is best to provide it with partial shade to partial sun conditions.
Temperature Requirements
This plant species is hardy and can tolerate a wide range of temperatures. It grows well in USDA zones 3 to 8 and can withstand winter temperatures of at least -40°F. The plant prefers cooler temperatures around 60°F to 75°F. However, it can survive in temperatures as low as 40°F and as high as 90°F, provided adequate moisture is available in the soil.
Soil Requirements
Deschampsia flexuosa (L.) Trin. ssp. montana (L.) A.& D. Löve prefers well-draining, slightly acidic soil with a pH range of 5.5 to 6.5. It thrives in soils with high organic matter content and prefers loamy, sandy, or rocky soils. The plant can tolerate dry soil conditions once established, but it prefers consistently moist soil. However, the soil must not be waterlogged as it can cause the roots to rot, resulting in plant death.
Cultivation Methods
Deschampsia flexuosa (L.) Trin. ssp. montana (L.) A. & D. Löve, commonly known as mountain hair-grass, is a cool-season, tussock-forming grass that is native to most parts of Europe, Asia, and North America. It is a hardy plant with a tolerance for a wide range of soil types, light conditions, and temperatures, making it an ideal addition to various plant communities. The plant can reach a height of up to 70 cm and spreads out between 20-30 cm. It has bright green leaves and distinct purple flowers that bloom in late spring or early summer.
Mountain hair-grass grows best in full sun but can also tolerate partial shade. The plant does well in a variety of soil types, including acidic, loamy, and sandy soils. It is also relatively drought-tolerant and can adapt well to dry conditions. To propagate, mountain hair-grass can be grown from seed or by dividing the clumps every three to four years.
Watering Needs
Mountain hair-grass does not have high water requirements and can thrive in dry conditions. However, young plants require regular watering until they establish strong root systems. Watering should be done deeply and infrequently, ensuring the soil dries out between watering. It is essential to avoid overwatering and waterlogging the soil, as this can lead to root rot and other diseases.
Fertilization
Mountain hair-grass does not require frequent fertilization. However, it can benefit from an annual application of a slow-release fertilizer during the early spring. In areas with poor soil fertility, applying organic compost or aged manure to the soil can provide the nutrients necessary for the plant to grow and thrive.
Pruning
Mountain hair-grass does not require pruning unless it is necessary for aesthetic reasons or to maintain a neat appearance. If pruning is necessary, it should be done during the plant's dormant period in late winter or early spring. The clumps should be divided every three to four years to prevent overgrowth and maintain the plant's vigorous growth.
Propagation of Deschampsia Flexuosa (L.) Trin. ssp. Montana (L.) A.& D. Löve
Deschampsia flexuosa (L.) Trin. ssp. montana (L.) A.& D. Löve is commonly known as the wavy hair-grass. It is a beautiful ornamental grass, often used in landscaping as ground cover or as border plantings. The plant can be propagated through several methods, each with its own advantages and disadvantages.
Propagation through Seeds
One of the easiest ways to propagate Deschampsia flexuosa (L.) Trin. ssp. montana (L.) A.& D. Löve is by sowing seeds. The best time to sow seeds is in the fall, as they require a cold period to germinate. The seeds must be planted shallowly in a well-draining soil mix and kept moist until they germinate. Usually, seedlings start to emerge after four to six weeks.
Propagation through Division
Division is another efficient method to propagate Deschampsia flexuosa (L.) Trin. ssp. montana (L.) A.& D. Löve. The best time to divide the plant is in early spring or late summer when the plant is dormant. The plant should be lifted from the ground and divided into smaller clumps, with each clump having its own roots and shoots. The divided clumps should be replanted immediately and kept well-irrigated until they establish.
Propagation through Stem Cuttings
Although not very common, stem cuttings can also be used to propagate Deschampsia flexuosa (L.) Trin. ssp. montana (L.) A.& D. Löve. The cuttings should be taken in late summer, choosing stems that are still green and semi-woody. The cuttings should be approximately 3 inches (8 cm) long, should be stripped of their lower leaves, and then planted in a well-draining soil mix. The cuttings should be kept moist and covered with a clear plastic bag placed over the pot until roots have established.
Disease Management
Deschampsia flexuosa ssp. montana is typically a healthy plant that is rarely affected by diseases. However, when the plant is grown in humid conditions or overcrowded areas, it may be susceptible to fungal diseases such as rust and powdery mildew.
To manage rust, remove and destroy infected plant parts immediately and clean up any fallen leaves or debris around the plant. Fungicides may also be used in severe infestations.
To manage powdery mildew, remove and destroy infected plant parts, improve air circulation around the plant, and avoid overhead watering. Fungicides may also be used as a preventative measure.
Pest Management
Deschampsia flexuosa ssp. montana may be susceptible to pests such as aphids and grasshoppers.
To manage aphids, use a strong spray of water to dislodge the pests from the plant. In severe infestations, insecticidal soap or neem oil may be used.
To manage grasshoppers, use physical barriers such as floating row covers to prevent them from accessing the plant. In severe infestations, insecticides may also be used.
