Description of Eriogonum thompsoniae S. Wats. var. thompsoniae
Eriogonum thompsoniae S. Wats. var. thompsoniae is a perennial wildflower species in the family Polygonaceae that is primarily native to the western United States, specifically the Great Basin area.
Common Names
The plant is commonly referred to as Thompson's Buckwheat or Thompson's Wild Buckwheat due to its discoverer, Zera Luther Thompson.
General Appearance
Thompson's Buckwheat is a low-growing shrub that typically reaches heights of up to 20 cm tall. Its leaves are long, narrow, and pale green, while its flowers are arranged in small, tight clusters that bloom from June through September.
The plant prefers to grow in moist to dry rocky habitats ranging from desert valleys to alpine slopes at elevations between 5,000 to 10,000 feet.
Uses
Historically, Eriogonum thompsoniae S. Wats. var. thompsoniae was used by Great Basin Native American tribes for a variety of medicinal purposes. However, the plant does not have any significant modern-day uses.
Light Requirements
Eriogonum thompsoniae S. Wats. var. thompsoniae is a plant that thrives in full sun environments. It requires at least 6 hours of direct sunlight per day for optimal growth. In shaded environments, the plant may grow slower and produce fewer blossoms.
Temperature Requirements
This plant grows best in a temperate climate with warm summers and cool winters. The ideal temperature range for Eriogonum thompsoniae S. Wats. var. thompsoniae is between 50? to 70? (10? to 20?). Extreme temperatures, either hot or cold, may harm the plant and slow down its growth.
Soil Requirements
The plant prefers well-draining soil with a slightly acidic to neutral pH level. It grows best in sandy or gravelly soils. The soil should be rich in minerals, and the plant requires good drainage as it doesn't do well with waterlogging. Additionally, the plant is tolerant of low-nutrient soils, but performs best when regularly fertilized with a balanced, organic fertilizer.
Cultivation
The Eriogonum thompsoniae S. Wats. var. thompsoniae or Thompson's buckwheat is a perennial plant that is native to the western United States. It is a drought-tolerant plant that prefers well-drained soils and plenty of sunlight.
Before planting, it is recommended to loosen the soil to allow air to penetrate. The plant is best propagated by seeds and cuttings from the mother plant. It is recommended to plant the seeds in spring or early summer when the soil is warm, and the danger of frost has passed.
Watering Needs
The Thompson's buckwheat is a drought-tolerant plant and requires minimal watering. During the first month of planting, the plant will need constant moisture to establish itself. After the plant becomes established, it will only require occasional deep watering. It is essential to avoid overwatering, as this can cause root rot.
Fertilization
The Thompson's buckwheat is a low-maintenance plant that typically does not require fertilization. However, if necessary, a slow-release, low-nitrogen fertilizer can be applied in the early spring or late fall.
Avoid using high nitrogen fertilizer as it will promote leafy growth and reduce flower production. Uncoated urea should be avoided as it can lead to root burn, which can damage or kill the plant.
Pruning
The Thompson's buckwheat does not require pruning, but removing dead flowers can promote the development of new blooms. Pruning is best done in early spring to remove any damaged or diseased branches. It is important to use clean and sharp pruning shears to prevent the spread of disease.
It is recommended to cut the plant back to about 1/3 of its original size to promote new growth in the spring. Regular pruning can also help to maintain the plant's shape and size.
Propagation of Eriogonum thompsoniae S. Wats. var. thompsoniae
Eriogonum thompsoniae S. Wats. var. Thompsoniae, commonly known as Thompson's buckwheat, is a low-growing, perennial plant that thrives in dry, rocky terrains. It is native to the western United States and is a popular choice for xeriscaping and landscaping. Propagation of this plant is relatively simple, and there are several methods that can be used.
Propagation by Seed
Eriogonum thompsoniae can be propagated by seed, which is collected in late summer and early fall when they are ripe. The seeds are then dried and stored until it is time to plant them. Plant seeds in the fall or spring in a well-draining soil mix that mimics the native habitat. Cover lightly with soil or sand, and water gently. Keep moist until germination occurs, which usually takes two to four weeks.
Propagation by Division
Eriogonum thompsoniae can also be propagated by division. Divide larger plants by carefully digging around the plant, loosening the soil, and separating the root mass. Each root ball should have a minimum of three to four healthy stems. Replant the divisions in well-draining soil, water thoroughly, and keep moist until established.
Propagation by Cuttings
Propagation by cuttings is another viable method for Eriogonum thompsoniae. Cuttings should be taken from actively growing plants during the summer. Select healthy stems and cut them just below the node. Remove the lower leaves from the cutting, dip the cut end in rooting hormone, and plant in a well-draining soil mix. Keep the soil moist but not waterlogged, and place in a shaded location until roots have developed, usually in four to six weeks.
Disease and Pest Management for Eriogonum thompsoniae S. Wats. var. thompsoniae
Eriogonum thompsoniae S. Wats. var. thompsoniae, commonly known as Thompson's buckwheat, is a perennial plant native to North America. Although generally resistant to diseases and pests, it can sometimes be affected by the following:
Diseases
Crown rot: Caused by the fungus Sclerotium rolfsii, this disease affects the roots and the base of the plant, causing the crown to rot. To manage it, remove infected plants and destroy them. Avoid overwatering and improve soil drainage. Treat the soil with fungicides before planting new Eriogonum thompsoniae.
Leaf spot: This fungal disease causes circular spots to appear on the leaves. To manage it, remove infected leaves and destroy them. Avoid overhead irrigation, as water on leaves can facilitate the spread of the disease. Treat the plant with fungicides, and ensure good air circulation around the plant.
Phytophthora root rot: Caused by the soil-borne fungus Phytophthora cinnamomi, this disease affects the roots and stem base, causing wilting and death. To manage it, remove infected plants and destroy them. Avoid overwatering and improve soil drainage. Treat the soil with fungicides before planting new Eriogonum thompsoniae.
Pests
Scales: These small insects suck the sap from the plant, causing stunted growth, leaf loss, and dieback. To manage them, use horticultural oils or insecticidal soaps. Prune heavily infested branches. Avoid fertilizing the plant with nitrogen-rich fertilizers, as they attract scales.
Aphids: These tiny insects feed on the sap of new growth, causing wilting and distorted leaves. To manage them, wash them off with a strong stream of water. Apply insecticidal soaps or neem oil. Introduce natural predators such as ladybugs and lacewings.
Spider mites: These tiny arachnids suck the sap from the plant, causing yellow or bronzed leaves, webbing, and eventual death. To manage them, wash them off with a strong stream of water. Apply insecticidal soaps or neem oil. Increase humidity around the plant to discourage mite activity.
