Overview of Elymus interruptus Buckl.
Elymus interruptus Buckl., commonly known as the American desert wheatgrass, is a species of grass found in North America. It belongs to the Poaceae family and is native to the western regions of North America, including the Great Basin, California, and the Southwest United States. The plant is commonly referred to as the American desert wheatgrass due to its natural habitat in arid regions.

The mature blades of the leaves are flat and about ¼ inch wide. The plant produces flowers on erect stems that stand above the foliage. The flowers are small, white, and are produced in dense greenish-white clusters that range from 2 to 10 inches long.
Uses of Elymus interruptus Buckl.
Elymus interruptus Buckl. is commonly used for soil stabilization in the dry regions of North America. The plant's strong roots help to hold the soil together and prevent soil erosion. It is also a popular grazing plant, providing food for livestock and wildlife. In addition, the plant has medicinal properties and is used as a traditional remedy for various ailments. The roots of the plant are used in combination with other herbs to make a tea that helps reduce fever, headaches, and digestive issues.
The plant is also valuable in landscaping for its aesthetic value. With its bluish-green foliage and delicate white flowers, it adds an attractive natural touch to any garden or landscape.
Overall, Elymus interruptus Buckl. is a versatile plant that has several uses, including soil stabilization, grazing, and medicinal purposes. Its unique appearance makes it an attractive addition to gardens and landscapes as well.Light Requirements
Elymus interruptus Buckl. thrives in full sun or partial shade. It requires at least six hours of direct sunlight daily to grow optimally. The plant may tolerate some shade in hot regions or at higher elevations.
Temperature Requirements
Elymus interruptus Buckl. grows best in cool soil and moderate temperatures. The plant is adapted to the temperature ranges typical of the intermountain region. It is hardy and can tolerate a broad range of temperatures between -33°C to 38°C (-27°F to 100°F).
Soil Requirements
Elymus interruptus Buckl. prefers well-drained soils. The plant can grow in a variety of soil types, but it does best in loamy or sandy soils with a pH range of 7.0 to 8.0. The plant is highly tolerant of saline soil conditions, making it suitable for cultivation in areas with high salinity levels.
Cultivation
Elymus interruptus Buckl. is an ornamental grass that is easy to grow and maintain. It prefers well-draining soils and needs to be planted in an area that receives full sunlight. The plant can be grown in USDA plant hardiness zones 5 to 9 and can be propagated through seed or division of clumps.
Watering
The plant needs moderate watering to thrive and should be watered deeply once a week during the summer. However, during the cooler months, the frequency can be reduced to every two weeks or so. The goal is to keep the soil moist but not waterlogged. Overwatering can lead to root rot and other issues that can damage the plant.
Fertilization
Elymus interruptus Buckl. is a low maintenance plant and does not require much fertilization. However, if the soil is poor in nutrients, one can add slow-release fertilizer when planting the grass in spring. Alternatively, one can top-dress with compost every spring to improve soil fertility. Fertilizers should be applied according to the manufacturer's guidelines, and excess use should be avoided as it can lead to the overgrown grass.
Pruning
Elymus interruptus Buckl. is a clumping grass that does not spread aggressively. However, if required, the plant can be pruned back to control its size or remove dead or damaged foliage. Pruning should be carried out in early spring before new growth emerges. The plants can be cut back to one-third of their height, and the cut stems can be left on the ground to act as mulch. Wearing gloves is advisable while pruning the plant, as the sharp leaf blades can cut fingers and hands.
Propagation of Elymus interruptus Buckl.
Elymus interruptus Buckl. is commonly propagated by seeds. However, it can also be propagated through rhizome division.
Propagation by Seeds
Propagation of Elymus interruptus Buckl. by seeds is a reliable method. It is recommended to sow seeds in the fall directly into the ground where they are intended to grow. Soil moisture is important during this process, and it is recommended to keep the soil moist until the seed germinates. It may take up to a year for the seed to germinate, and the plant may take several years to reach maturity depending on growing conditions.
It's essential to ensure that the seeds collected are viable. Seeds from dormant plants are usually viable, but the viability decreases with time. Germination tests can be performed to determine the viability of the seeds.
Propagation through Rhizome Division
Elymus interruptus Buckl. may be propagated by dividing the rhizomes. This method is usually preferred by gardeners as the new plants are mature and produce quicker results than seedlings. The best time to divide the rhizomes is during the growing season, typically in spring or fall.
Dig up the mature plant gently, shake off the soil and remove the dead parts of the rhizome. Separate the rhizomes carefully and replant them in separate containers or parts of a garden bed. It’s crucial to water the newly divided plants frequently to keep the soil moist as they are becoming established.
Disease and Pest Management for Elymus interruptus Buckl.
Elymus interruptus Buckl. is a perennial grass species native to North America. Although it is relatively resistant to most diseases and pests, it may still be affected by some common issues that can cause severe damage if left untreated. Below are the most common diseases and pests that might affect Elymus interruptus and some ways to manage them.
Common Diseases
Crown and Root Rot: Crown and root rot are fungal diseases that cause wilted foliage and yellowing blades. Affected plants may show signs of stunted growth and may eventually die if not treated. To manage crown and root rot, avoid overwatering and provide proper drainage. Fungicides can also be applied to infected plants to control the spread of the disease.
Leaf Rust: Leaf rust is a fungal disease that causes yellow or brown lesions on foliage. Severe infections may cause leaf drop and weaken the plant. To manage leaf rust, remove and destroy infected plant parts and provide proper air circulation. Fungicides can be used to control the disease if necessary.
Common Pests
Aphids: Aphids are small insects that suck sap from the plant's leaves and stems, causing damage to the foliage and distorting new growth. To manage aphids, use insecticidal soap or neem oil, or encourage beneficial insects like ladybugs that feed on them.
Grasshoppers: Grasshoppers are voracious feeders that can cause significant damage to the plant's foliage and reduce its growth. To manage grasshoppers, use organic pesticides or mechanical methods like handpicking or trapping to control their population.
Proper cultural practices like regular watering, fertilization, and pruning can also help maintain the overall health of Elymus interruptus and prevent diseases and pests from occurring. It's essential to monitor the plant regularly and take appropriate action when necessary to keep it healthy and thriving.
