Plant Overview

×Elymordeum dakotense Bowden, commonly known as Dakota wildrye, is a perennial plant that belongs to the Poaceae family. This plant is a hybrid resulting from the cross-pollination between ×Elymus canadensis and Elymus lanceolatus. It is indigenous to North America and can be found in the Great Planes region.

Common Names

Dakota wildrye is commonly known by several vernacular names, including Big Bluestem x Wild Rye hybrid, Elymordeum, and Bowden's Wildrye. It is important to note that the name Dakota wildrye is associated with another species in the same family, Elymus reconditus, therefore referring to it as ×Elymordeum dakotense is more accurate.

Appearance

×Elymordeum dakotense Bowden has a unique and eye-catching appearance. This plant has thin leaves that are narrow and long, measuring up to 60 cm. Its stem is erect and can grow up to 1.5 meters tall. The flower heads of this plant are compact and have several florets that contain awns. The flowers bloom between May and August and have a greenish tint. The plant's roots can grow 2 meters deep, which makes it well-adapted to the dry conditions of the Great Planes region.

Uses

There are several uses of ×Elymordeum dakotense Bowden. One of the most prominent is erosion control. This plant's deep roots make it suitable for preventing soil erosion in sloping areas. Additionally, its distinctive appearance makes it a top pick for landscaping and ornamental purposes. The plant's ability to withstand drought conditions makes it an important forage crop for livestock in the Great Planes region. Lastly, Dakota wildrye is used in the restoration of prairie ecosystems, where its deep roots help maintain soil health and structure and provide habitat for native flora and fauna.

Light Requirements

×Elymordeum dakotense Bowden thrives best in full sun exposure. It requires a minimum of six hours of direct sunlight each day to grow healthy foliage and produce flowers. Lack of sunlight can result in a weak and spindly plant. If planted in a shaded place, the plant may not blossom or produce seeds.

Temperature Requirements

The plant is endemic to North Dakota, where it faces a continental climate that involves harsh winters and hot summers. The plant can tolerate freezing temperatures of up to -30 degrees Fahrenheit in winter but it prefers a consistent temperature range of 60 to 80 degrees Fahrenheit during the growing period. The plant can survive and grow in hot temperatures as high as 90 degrees Fahrenheit, although it may require frequent irrigation in extreme heat.

Soil Requirements

It prefers medium to well-draining sandy soil but can tolerate shallow and rocky soil as well. The plant grows well in soil with a pH range of 6.6 to 7.5. Excess water in the soil can lead to root rot, so it is necessary to ensure proper drainage, especially when planting in clay soil. The plant may also benefit from the addition of organic matter, such as compost or manure, to enhance soil fertility and texture.

Cultivation

When cultivating ×Elymordeum dakotense Bowden, it is essential to ensure that the plant gets enough sunlight, as partial shade may result in poor growth. The plant prefers well-drained soil and grows best in sandy or loamy soils with a neutral pH range of 6.0-7.5.

Propagation can be done through seed germination, division, and root cuttings. Seed germination is best done in spring, and the seedlings can be transplanted after about six weeks. Division can be carried out in early spring or fall when the plants are dormant. Root cuttings can be taken in spring or fall, and the cuttings should be planted vertically in a well-drained location.

Watering Needs

Watering ×Elymordeum dakotense Bowden is vital during the growing season, and the plant will need at least an inch of water per week. Care should be taken to avoid overwatering, as this can lead to root rot. The plant can withstand drought once established, but young plants require consistent moisture.

Fertilization

The plant does not require much fertilization but benefits from a light application of an organic fertilizer every spring. It is crucial to avoid fertilizing the plant in the late summer and fall, as this can lead to weak growth and winter damage.

Pruning

Pruning ×Elymordeum dakotense Bowden is not necessary, as the plant has a natural bushy growth habit. However, it is advisable to remove any dead or diseased stems in the early spring to promote healthy growth. The plant does not require pruning to maintain its shape, but cutting back after flowering can result in new growth and a denser plant.

Propagation of xElymordeum dakotense Bowden

xElymordeum dakotense Bowden, commonly known as tall wheatgrass, can be propagated by either seed or division.

Seed Propagation

The best time to propagate tall wheatgrass through seed is during the fall season when the soil temperature is cooler. The seeds can be directly sowed in the garden beds or in seed trays indoors. Here’s how to propagate tall wheatgrass through seed:

1. Collect the seeds from a mature plant and remove any debris or unwanted materials from the seeds.
2. Place the seeds in a container with cool water for 24 hours to allow for proper hydration.
3. Plant the seeds in a well-draining soil mix, covering them with only a thin layer of soil.
4. Keep the soil moist and in a warm and well-lit area. The seeds should germinate in about 2-4 weeks.
5. Once the seedlings have reached a height of about 6 inches, they can be transplanted into garden beds.

Division Propagation

Tall wheatgrass can also be propagated by dividing mature plants. Here’s how to propagate tall wheatgrass through division:

1. Dig up the mature plant carefully, making sure to avoid damaging the roots.
2. Divide the plant into several smaller sections, making sure that each section has both roots and shoots.
3. Plant each section in a well-prepared soil mix, making sure to water well and provide adequate light.
4. Keep the newly planted divisions well-watered until they become established and start to grow.

Regardless of the propagation method, tall wheatgrass should be grown in a sunny location and given plenty of water during the growing season. With proper care, tall wheatgrass can be propagated successfully, and will make a beautiful addition to any garden.

Disease and Pest Management for ×Elymordeum dakotense Bowden

Although ×Elymordeum dakotense Bowden is a hardy plant, it is still susceptible to several diseases and pests. Here are some common issues that might affect the plant and ways to manage them:

Diseases

1. Leaf Rust - Leaf rust is a fungal disease that affects the leaves of the plant. Symptoms include yellow or white spots on the leaves, which eventually turn into brown or red pustules. To manage this disease, prune the affected leaves and dispose of them. Also, avoid overhead watering, as it can promote the spread of the disease. Applying a fungicide can help prevent the spread of leaf rust.

2. Stem Rust - Stem rust is another fungal disease that affects the stem of the plant. Symptoms include reddish-brown spores on the stem. To manage this disease, prune the affected parts of the stem and dispose of them. Applying a fungicide can help prevent the spread of stem rust.

Pests

1. Grasshoppers - Grasshoppers are a common pest that can cause extensive damage to ×Elymordeum dakotense Bowden. Symptoms of grasshopper damage include holes in the leaves and stems of the plant, which can lead to stunted growth. To manage this pest, spray the plant with an insecticide, or use a homemade spray of water and dish soap.

2. Aphids - Aphids are tiny insects that suck the sap out of the plant, leading to stunted growth and yellowing leaves. Symptoms of aphid infestation include curled or twisted leaves. To manage this pest, introduce natural predators like ladybugs or lacewings. Alternatively, spray the plant with an insecticide.

By monitoring and managing the diseases and pests that affect ×Elymordeum dakotense Bowden, you can ensure that the plant remains healthy and vibrant for years to come.
