It is also known by other common names such as western wild rye, mountain wild rye, and western wildrye.General Appearance
The hairy glume wildrye typically grows up to 3 feet tall and has a dense, clumping growth habit. Its leaves are long and narrow, with a blue-green color and a coarse texture. The plant's inflorescence is a dense, cylindrical spike that can reach up to 6 inches in length and is composed of numerous tiny florets. These florets usually bloom from June to August and may have a green, purple or brown color. The seeds of the hairy glume wildrye are small, oblong, and covered with fine hairs. They are usually dispersed by wind, and the plant can also spread through rhizomes.Uses
Elymus hirsutiglumis Scribn. has several practical and ecological applications. It is a great palatable forage crop for livestock grazing and is often included in seed mixtures for rangeland restoration. The dense root system of the plant helps stabilize soil, prevent erosion, and improve water quality by absorbing excess nutrients and pollutants. In addition, the hairy glume wildrye is often used for landscaping due to its tolerance of drought, cold temperatures, and poor soil conditions. Its attractive seed heads and foliage provide visual interest in gardens, and it is a low-maintenance plant that requires minimal attention. In summary, the Elymus hirsutiglumis Scribn. is a native grass species that has various ecological, agricultural, and landscaping uses. Its tall stature, coarse leaves, and dense inflorescence make it an eye-catching plant with both form and function.Typical Growth Conditions for Elymus hirsutiglumis Scribn.
Elymus hirsutiglumis Scribn., also known as hairy glume wildrye, is a perennial grass species that is native to North America. It is commonly found in prairies, savannas, and open forests, and it has adapted to a range of environmental conditions.
Light Requirements
Elymus hirsutiglumis requires full to partial sunlight to grow and thrive. This grass species is known to tolerate shade to some extent, but it prefers open areas with plenty of sunshine. Therefore, it is commonly found in natural habitats where it can receive adequate amounts of sunlight for photosynthesis.
Temperature Requirements
Elymus hirsutiglumis can grow in a wide range of temperatures. This species is adapted to temperate and subarctic climates, and it can tolerate extreme temperature fluctuations. The optimal growth temperature is between 15-25°C (59-77°F), but it can also grow in some areas with temperatures outside of this range.
Soil Requirements
Elymus hirsutiglumis can grow in a variety of soil types, including loamy, sandy, and gravelly soils. It prefers well-drained soils that are not too compacted, as this allows proper root development and nutrient uptake. This grass species has a moderate tolerance to drought and can survive in areas with low moisture, it also tolerates periodic flooding. A slightly acidic soil pH of 6.0-7.0 is optimal for growth and development.
Cultivation Methods
Elymus hirsutiglumis Scribn., commonly known as hairy glumes wheatgrass, is a cool-season, long-lived perennial grass species that is native to the western United States. It thrives in various soil types, including gravelly soils, clayey soils, and loamy soils, but prefers well-drained soils. It also prefers full sun but can tolerate partial shade.
The plant can be propagated using seeds or vegetatively. If using seeds, they should be sown in the spring or fall on a prepared seedbed with good soil contact, and the soil should be kept moist before and after germination. Vegetative propagation is achieved through tillers, crown division, or rhizomes.
Watering Needs
Hairy glumes wheatgrass requires moderate watering, especially during the establishment period. The plant should be watered regularly to keep the soil moist but not waterlogged. The amount of water required will depend on several factors such as the temperature, humidity, and soil type. During the growing season, the plant should be watered deeply and infrequently to encourage deep root development.
Fertilization
The plant does well in soils with low to moderate fertility, and consequently, it usually does not require fertilizer. However, in cases where the soil is deficient, appropriate levels of nitrogen, phosphorus, and potassium can be added. Nitrogen can be supplied either through organic or inorganic fertilizer. Still, it should be applied sparingly to avoid excessive vegetative growth, particularly in the seedling stage. A soil test can help determine the specific nutrients required.
Pruning
Elymus hirsutiglumis Scribn. generally does not require pruning, except in cases where the plant has become too large and overgrown. When pruning, it is important to remove only about a third of the plant mass at any given time to avoid shock and damage to the plant. Additionally, pruning should be done during the cooler months when the plant is the least active. Removing damaged, diseased, or dead plant parts promptly is essential for maintaining the health of the plant.
Propagation of Elymus hirsutiglumis Scribn.
Propagation of Elymus hirsutiglumis Scribn. can be achieved through seeds and vegetative means.
Propagation by Seeds
Seeds are the most common method of propagation for Elymus hirsutiglumis Scribn. The plant produces ample seeds, which can be collected for propagation. Seeds should be sown in the late fall to early spring to allow for the cold stratification period required for germination.
Seeds can be sown directly in the ground or started in pots before being transplanted. The soil should be moist and well-draining for successful germination.
Propagation by Vegetative Means
Elymus hirsutiglumis Scribn. can also be propagated by vegetative means such as division and rhizomes. Division involves separating the plant into smaller sections, each with its own roots and leaves, which can be transplanted to start a new plant.
Rhizomes are underground stems that can produce new plants if separated. The rhizomes should be dug up in the early spring or fall and separated, making sure each section has several buds. The separated rhizomes can then be replanted in a new location.
Disease Management
Elymus hirsutiglumis Scribn. is generally a hardy plant that is not affected by many diseases. However, there are a few diseases that may affect the plant:
- Leaf rust: This fungal disease can be identified by numerous small, round, bright yellow spots that appear on the leaves. These spots can spread quickly and cause the leaves to turn brown and die. To manage leaf rust, infected leaves should be removed and destroyed, and the plant should be treated with an appropriate fungicide.
- Powdery mildew: This fungal disease shows as a white, powdery coating on the leaves and stems. It can cause stunted growth and reduce the overall health of the plant. To manage powdery mildew, improve air circulation, ensure proper drainage, and treat with a fungicide, if necessary.
Pest Management
Elymus hirsutiglumis Scribn. is also generally pest resistant, but there are a few insects that may cause damage to the plant:
- Armyworms: These pests are most active in the late summer and early fall and can cause significant damage to the leaves and stems of the plant. To manage armyworms, remove any infected plant debris, spray the plant with an insecticide, and use beneficial insects to control the population.
- Wireworms: The larvae of the click beetle, wireworms can cause significant damage to the roots of the plant. To manage wireworms, ensure proper soil drainage, avoid over-fertilizing, and use insecticidal treatments as necessary.
