Danthonia intermedia Vasey var. cusickii Williams, commonly known as Cusick's oatgrass, is a native perennial grass that can be found in the western United States. The plant belongs to the Poaceae family and is frequently identified by its tall and delicate appearance.

Common Names

Cusick's oatgrass is a generally recognized common name, but it is also known as intermediate oatgrass or smallflowered oatgrass.

Uses

Cusick's oatgrass contributes to the soil by binding with essential nutrients and improving soil erosion resistance. Cattle and sheep also forage on the grass as a food source. The plant has been used for restoration projects and reclamation efforts

General Appearance

Cusick's oatgrass typically grows in clumps with a height between 20 to 60 centimeters. The leaves are long and straight with a flat appearance. The plant's flowers grow on erect stems and possess small seeds with awns projecting from them. Cusick's oatgrass is distinguished from other oatgrasses by its smaller seeds with narrow, sharp, and pointed lemmas that are distinctly awned.

Light Requirements

Danthonia intermedia Vasey var. cusickii Williams requires full to partial sun exposure to grow properly. It can tolerate some shade, but too much shade can cause stunted growth and reduced flowering.

Temperature Requirements

This plant is native to the Pacific Northwest region of the United States, where it typically grows in cool, moist habitats. It can tolerate a range of temperatures, but it prefers cool to moderate conditions, with temperature ranges between 50°F to 75°F (10°C to 24°C) being optimal for its growth.

Soil Requirements

Danthonia intermedia Vasey var. cusickii Williams grows well in well-draining soils that are rich in organic matter. It prefers slightly acidic to neutral soils with a pH range of 5.5 to 7.0. It can tolerate a range of soil types, but it prefers sandy or loamy soils over heavy clay soils. It also requires adequate moisture levels to grow, but it can tolerate some drought conditions once it is well-established.

Cultivation

Danthonia intermedia Vasey var. cusickii Williams is a perennial plant that grows well in dry to medium soil types. It prefers soils with neutral to slightly acidic pH levels. This plant is native to the Western United States and can be grown in various hardiness zones.

This species can be propagated through seed or division in the spring or fall during the growing season. Plant the seedlings or divisions in well-draining soil in a sunny location. Ensure that the soil is well-prepared by loosening it and adding compost or organic matter before planting.

Watering needs

Danthonia intermedia Vasey var. cusickii Williams is drought-tolerant and can survive in dry conditions. However, it requires sufficient watering during the establishment phase. Once the plant has established, it can be watered occasionally, and the watering frequency can be reduced during its dormant phase.

The watering amount and frequency may vary depending on the soil type and weather conditions. Water the plant deeply, and avoid wetting the foliage to prevent diseases.

Fertilization

Danthonia intermedia Vasey var. cusickii Williams does not require frequent fertilization. You can fertilize the plant during its growing season using a balanced fertilizer formula. Apply the fertilizer sparingly, so as not to encourage excessive growth or damage the plant.

Alternatively, you can add organic matter or compost to the soil before planting, and this will provide the necessary nutrients to the plant during its entire growing season.

Pruning

Danthonia intermedia Vasey var. cusickii Williams does not require frequent pruning. Pruning is only necessary to remove diseased, damaged, or dead leaves or stems. You can prune the plant before its growing season or after it has bloomed.

Use a clean pair of garden shears or scissors to make cuts at a 45-degree angle. Avoid cutting too close to the base of the plant, as this can damage the plant and prevent regrowth.

Propagation of Danthonia intermedia Vasey var. cusickii Williams

There are several ways to propagate Danthonia intermedia Vasey var. cusickii Williams:

Seed Propagation

Danthonia intermedia Vasey var. cusickii Williams can be propagated from seeds. The best time to collect the seeds is during late summer when the seed heads turn brown. The seeds should be collected and cleaned before storing. To ensure germination, the seeds should be exposed to cold stratification before planting. The seeds should be sown in a well-draining soil mix and covered with a thin layer of sand or soil. The pots should be placed in a warm and sunny location and watered regularly. The seeds should germinate in 2-3 weeks if conditions are ideal.

Division

Danthonia intermedia Vasey var. cusickii Williams can also be propagated by division. The best time to divide the plant is in early spring before new growth begins. The plant should be carefully dug up and the roots should be teased apart. Each division should have several shoots and a healthy root system. The divisions can be replanted in a well-draining soil mix and watered regularly. They should be placed in a warm, sunny location and allowed to establish before being transplanted.

Cuttings

Although Danthonia intermedia Vasey var. cusickii Williams can be propagated from stem cuttings, it is not the most reliable method. The cuttings should be taken from new growth and should be around 4-6 inches in length. The cuttings should be planted in a well-draining soil mix and placed in a warm and sunny location. The cuttings should be watered regularly, and misted to increase humidity. Rooting should occur in approximately 4-6 weeks if conditions are ideal.

Disease Management

Danthonia intermedia Vasey var. cusickii Williams is known for being a generally disease-resistant plant. However, some diseases may still affect this grass species. Here are some common diseases that may affect Danthonia intermedia:

• Leaf spot: This fungal disease appears as brown or black spots on the leaves. To manage it, it's best to remove and destroy any affected leaves.
• Crown rot: This fungal disease causes the plant's crown to rot, eventually killing the plant. The best way to prevent crown rot is to avoid overly wet soil conditions.
• Root rot: Similar to crown rot, root rot is a fungus that attacks the plant's roots. To manage it, make sure the plant is planted in well-draining soil and avoid over-watering.

Pest Management

Like diseases, pests are not a major concern with Danthonia intermedia Vasey var. cusickii Williams. However, here are some common pests that may affect this plant:

• Aphids: These tiny insects feed on the plant's sap, causing stunted growth and yellow leaves. To manage them, try spraying the plant with a solution of water and dish soap.
• Spider mites: These pests are difficult to see, but they can cause significant damage to the plant's foliage if left unchecked. Try spraying the plant with water to knock them off or use an insecticidal soap.

Overall, disease and pest management for Danthonia intermedia Vasey var. cusickii Williams is relatively simple. Good growing practices, such as planting in well-draining soil and avoiding over-watering, can go a long way in preventing both diseases and pests. If problems do occur, there are a variety of environmentally safe treatments available that can help protect this beautiful ornamental grass.
