Common Names
Harney clover is the most commonly used name for Trifolium eriocephalum Nutt. var. harneyense (T.J. Howell) McDermott. However, it is also known by several other common names, including woollyhead clover, woolly clover, and hairyhead clover.
Uses
Harney clover has several uses, both for human and animal consumption. Its seeds are edible and can be used as a source of protein. Additionally, its leaves and stems can be used for forage for livestock. Harney clover also has medicinal properties and has been used historically by Native American tribes to treat various health conditions such as headaches and stomach pains.
General Appearance
Harney clover is a herbaceous perennial plant that typically grows to be about 0.3 to 1 meter tall. Its leaves are trifoliate, meaning that they are composed of three leaflets. The leaflets are typically oval-shaped and can be up to 2.5 cm long. The plant produces hairy, ball-shaped flower heads that are typically pink or purple in color. The flowers bloom from May to July and produce small seeds that are housed in pods.
Light Requirements
Trifolium eriocephalum Nutt. var. harneyense typically grows best in full sunlight. In order to receive optimal growth and seed production, it requires at least 6 hours of direct sunlight a day.
Temperature Requirements
This plant is indigenous to regions with a cold, semi-arid climate with hot summers and short, cold winters. To thrive, it requires a minimum temperature of 60°F and a maximum temperature of 85°F. Excessively hot or cold temperatures can hinder growth or even cause it to wilt.
Soil Requirements
Trifolium eriocephalum Nutt. var. harneyense typically prefers soils that are well-draining and slightly acidic, with a pH between 5.5 and 6.5. Sandy loam soil is also preferred, but it can tolerate other soil types within reason. The plant requires adequate soil moisture but cannot tolerate standing water; therefore, it is essential to ensure proper drainage.
Cultivation of Trifolium eriocephalum Nutt. var. harneyense
Trifolium eriocephalum Nutt. var. harneyense is typically grown from seed and can be propagated through division. The ideal planting time for this plant is in the fall, but it can also be planted in the early spring. It is important to choose a location that receives full sun or partial shade and has well-drained soil.
Watering Needs
Trifolium eriocephalum Nutt. var. harneyense requires moderate watering. It is important to keep the soil moist but not waterlogged, as this can cause root rot. During the summer months, the plant may require more frequent watering.
Fertilization
Trifolium eriocephalum Nutt. var. harneyense does not require heavy fertilization and can be maintained with light fertilization once or twice a year. A balanced fertilizer with a 10-10-10 ratio can be used. It is important to follow the manufacturer's instructions for the correct amount of fertilizer to use.
Pruning
Pruning can help to promote the growth and longevity of Trifolium eriocephalum Nutt. var. harneyense. It is best to prune the plant in the early spring before new growth appears. Dead or damaged branches should be removed, and the plant can be shaped to promote a fuller and more compact growth habit.
Propagation of Trifolium eriocephalum Nutt. var. harneyense (T.J. Howell) McDermott
Trifolium eriocephalum Nutt. var. harneyense (T.J. Howell) McDermott or Harney clover is a small, perennial herbaceous plant that belongs to the family Fabaceae. It is native to the Pacific Northwest region of North America, particularly in Harney County, Oregon.
This plant species is an important forage for livestock, and it also serves as a nitrogen fixer for soil improvement. If you want to propagate Trifolium eriocephalum Nutt. var. harneyense, here are some of the methods that you can consider:
Direct Seeding
One of the easiest ways to propagate Trifolium eriocephalum Nutt. var. harneyense is through direct seeding. This method involves sowing the seed directly into the ground in the fall or early spring when the soil is moist. It is important to prepare the soil first by removing any weeds and adding organic matter to improve the soil's fertility.
Transplantation
Another method to propagate Trifolium eriocephalum Nutt. var. harneyense is through transplantation. This method involves growing the plant from seedlings or cuttings and then transplanting them into the soil. This method can be more labor-intensive, but it can also provide better control over the plant's growth and quality.
Vegetative Propagation
Trifolium eriocephalum Nutt. var. harneyense can also be propagated through vegetative propagation methods. This includes techniques such as division, layering, and root or stem cuttings. Vegetative propagation can be an effective way to produce genetically identical plants and bypass the seedling stage for faster establishment.
In conclusion, Trifolium eriocephalum Nutt. var. harneyense can be propagated through various methods such as direct seeding, transplantation, and vegetative propagation. Each method has its advantages and disadvantages, and it is important to choose the appropriate method depending on the grower's needs and resources.
Disease and Pest Management for Trifolium eriocephalum Nutt. var. harneyense
Trifolium eriocephalum Nutt. var. harneyense is generally a hardy plant species that is resistant to most diseases and pests. However, here are some diseases and pests that can commonly affect the plant and tips on how to manage them:
Diseases
Anthracnose
Anthracnose is a fungal disease that can cause wilting and yellowing of leaves, stem dieback and cankers on stems of Trifolium eriocephalum Nutt. var. harneyense. To manage anthracnose, remove and destroy all infected plant parts. Avoid overhead watering and make sure to water the plants at soil level. Apply fungicide containing copper hydroxide or copper sulfate regularly to prevent further infections.
Powdery Mildew
Powdery mildew appears as white powdery coating on the leaves and stems of Trifolium eriocephalum Nutt. var. harneyense. The leaves may turn yellow and wilt, and the plant may become stunted. To manage powdery mildew, remove and discard the infected leaves and avoid overhead watering. Apply fungicide containing neem oil or potassium bicarbonate regularly to prevent further infections.
Pests
Aphids
Aphids are small, soft-bodied insects that can suck sap from the leaves and stems of Trifolium eriocephalum Nutt. var. harneyense, causing curling, yellowing and stunted growth. To manage aphids, rinse the plant with a strong jet of water to dislodge the insects. Apply insecticidal soap or neem oil to the plant regularly to prevent re-infestation.
Leafhoppers
Leafhoppers are small, wedge-shaped insects that can cause stippling and yellowing of the leaves of Trifolium eriocephalum Nutt. var. harneyense. They may also transmit plant diseases. To manage leafhoppers, remove any weed or grassy growth around the plant to eliminate their breeding grounds. Use insecticidal soap or neem oil regularly to prevent re-infestation.
