Thompson's buckwheat is a low-growing plant that can grow up to 6 inches in height and up to 3 feet in width. It has small, gray-green leaves that are spoon-shaped and hairy. The plant produces clusters of white to pinkish flower heads that are arranged in dense, round-shaped clusters that sit on top of the plant's stems. These flowers bloom from May to August.
Uses
Thompson's buckwheat has been traditionally used by indigenous people for its medicinal properties. The plant contains compounds that have been shown to possess antibacterial, antioxidant, and anti-inflammatory properties. Also, the honey produced from the plant's flower heads has a unique flavor and aroma that is sought after by honey enthusiasts. Additionally, the plant is used for landscaping because of its drought-tolerant nature and beautiful flowers.
Conservation Status
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal is considered a rare and threatened species due to habitat loss, land development, and climate change. The plant's population is declining, and its natural habitats are under significant threat. Conservation efforts are required to protect this species from extinction.
Light Requirements
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal grows best in full sun exposure, receiving at least six hours of direct sunlight daily. It has a high tolerance for intense sunlight, making it an excellent choice for open and sunny locations. However, the plant might experience heat stress and sunscald if exposed to excessive light and UV radiation.
Temperature Requirements
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal prefers moderate temperatures and grows well in regions with mild to warm climates. The plant thrives in a temperature range of 60°F to 90°F and is relatively cold and heat tolerant. However, it may suffer frost damage if grown in extremely cold conditions or areas with frosty weather such as below 20°F.
Soil Requirements
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal prefers well-drained soils with a slightly acidic to alkaline pH range between 6.0 to 7.5, albeit it can tolerate slightly higher or lower pH levels. It thrives in sandy, loamy, and rocky soils, but cannot withstand swampy and poorly drained soils. The plant's roots may rot if exposed to damp conditions, so it requires a consistently well-draining substrate.
Cultivation Methods for Eriogonum thompsoniae S. Wats. var. albiflorum Reveal
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal is a low-maintenance plant that can grow in different soil types. However, the ideal soil type for this plant is well-draining soil. It can tolerate both partial shade and full sun conditions. Therefore, it is essential to plant this species in a location that provides adequate sunlight and proper drainage.
Watering Needs for Eriogonum thompsoniae S. Wats. var. albiflorum Reveal
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal is a drought-tolerant plant, meaning it requires low water. It is crucial to avoid overwatering this plant, as it may lead to root rot. Therefore, we recommend watering this plant only when the top layer of soil is dry. Generally, one inch of water per week is sufficient for the plant's growth and development.
Fertilization for Eriogonum thompsoniae S. Wats. var. albiflorum Reveal
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal is a plant that thrives in nutrient-poor soil. Therefore, there is no need to fertilize it regularly. However, if the soil is severely nutrient deficient, applying a balanced organic fertilizer will be appropriate for the plant's growth.
Pruning Eriogonum thompsoniae S. Wats. var. albiflorum Reveal
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal is a plant that doesn't require much pruning. However, removing the dead or diseased plant parts will promote healthy growth. Pruning is best done in the early spring season or after the plant has finished flowering. This species can benefit from selective pruning to encourage a compact growth habit as well.
Propagation of Eriogonum thompsoniae S. Wats. var. albiflorum Reveal
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal, also known as Thompson's Buckwheat, can be propagated through different methods such as seeds, cuttings, or division.
Seeds
Seeds from mature Eriogonums can be collected when the seed heads start to dry on the plant. It is recommended to collect seeds in the morning when the dew has dried. Remove the seeds from the seed heads and store in a cool and dry place until ready to plant. The planting time should be in the early fall, and the seeds should be planted in well-drained soil that has been prepared by removing weeds and rocks. Cover the seeds with a thin layer of fine soil and keep moist until germination, which could take up to three months.
Cuttings
Another propagation method is through cuttings. Take cuttings from the plant in late spring or early summer, when the plant is actively growing. Use a sharp and clean knife to take a cutting that is around 3-4 inches long. Remove the lower leaves, and dip the bottom of the cutting in rooting hormone. Place the cutting in a pot with moist sand or a well-draining potting mix. Cover the pot with a plastic bag to maintain high humidity. Keep the cutting out of direct sunlight and keep the soil moist until roots develop.
Division
The third propagation method is through division. Divide Eriogonum thompsoniae S. Wats. var. albiflorum Reveal in the early spring, when new growth has started. Gently dig out the clumps without damaging the roots. Separate the clumps into sections, making sure that each division has some roots and leaves. Plant each cuttings in a prepared soil and keep it well-watered until established.
Disease Management
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal is generally a healthy plant, but it may be susceptible to several diseases. Here are some common diseases that can affect the plant:
- Rust: Rust is a fungal disease that appears as yellow-orange spots on the leaves. To prevent rust, it is important to provide good air circulation around the plant and avoid overwatering. Fungicides may also be used to manage rust.
- Leaf blight: Leaf blight is a fungal disease that causes brown or black spotting on the leaves. To manage leaf blight, infected leaves should be removed and destroyed. Fungicides may also be used to manage the disease.
- Root rot: Root rot is a fungal disease caused by overwatering and poor drainage. To manage root rot, it is important to improve drainage, avoid overwatering, and remove infected plants to prevent the spread of the disease.
- Powdery mildew: Powdery mildew is a fungal disease that causes a white powdery coating on the leaves. To manage powdery mildew, it is important to provide good air circulation around the plant and avoid overwatering. Fungicides may also be used to manage the disease.
Pest Management
Eriogonum thompsoniae S. Wats. var. albiflorum Reveal may attract several pests that can cause damage to the plant. Here are some common pests that can affect the plant:
- Aphids: Aphids are small, soft-bodied insects that can cause significant damage to the plant. To manage aphids, it is important to physically remove them from the plant using a strong stream of water or by using insecticidal soap.
- Spider mites: Spider mites are tiny pests that can cause yellowing and stippling on the leaves. To manage spider mites, it is important to physically remove them from the plant using a strong stream of water or by using insecticidal soap.
- Thrips: Thrips are small insects that feed on the leaves of the plant, causing stippling and distortion. To manage thrips, it is important to physically remove them from the plant using a strong stream of water or by using insecticidal soap.
- Whiteflies: Whiteflies are small, white insects that can cause significant damage to the plant. To manage whiteflies, it is important to physically remove them from the plant using a strong stream of water or by using insecticidal soap.
Regularly inspecting plants and promptly removing any pests or diseased leaves can help prevent the spread of disease and pest infestations. Also, using organic pest control methods like insecticidal soap or neem oil can be effective in managing pests.
