Origin
Eriogonum capistratum Reveal var. muhlickii Reveal, commonly known as Muhlick’s Buckwheat, is a flowering plant belonging to the family Polygonaceae. It is a native plant of North America, specifically found in the western United States, including California, Nevada, and Arizona.
Common Names
Muhlick’s Buckwheat is the most recognized common name for Eriogonum capistratum Reveal var. muhlickii Reveal. The plant is also known as Capistrano Buckwheat due to its previous classification as a subspecies of Eriogonum capistratum.
Uses
The plant has several uses, especially in the horticultural world. Muhlick’s Buckwheat is often used in landscaping and erosion control due to its drought-tolerant nature and low maintenance requirements. In addition, it has ornamental value, as its pink-colored flowers attract butterflies and other pollinators. Native Americans also used the plant to treat digestive problems and skin irritations.
General Appearance
Eriogonum capistratum Reveal var. muhlickii Reveal is a perennial plant growing up to 1 foot tall and 1.5 feet wide. It has a mound-like habit and a rounded shape, with intricate branching. The leaves are small, gray-green in color, and shaped like a spatula. The plant produces flowers from June to August, which are small, pink, and gathered in rounded clusters. Muhlick’s Buckwheat tolerates most soil types, except those that are poorly drained and wet.
Light Requirements
Eriogonum capistratum var. muhlickii requires full sunlight to grow properly. It can tolerate some partial shade but will not thrive in shaded areas.
Temperature Requirements
This plant is native to the warm and arid climates of the western United States. It can withstand high temperatures and drought conditions but does not tolerate extreme cold. The ideal temperature range for Eriogonum capistratum var. muhlickii is between 60-90°F (15-32°C).
Soil Requirements
Well-draining soils are crucial for the growth of Eriogonum capistratum var. muhlickii. This species can tolerate a range of soil types, including clay, loam, and sandy soils. However, the soil should be nutrient-rich and have a pH level between 6.0-8.0. Avoid soils that are waterlogged or prone to flooding as this can be detrimental to the plant's growth.
Cultivation Methods
Eriogonum capistratum Reveal var. muhlickii Reveal, commonly known as Muhlick's Buckwheat, is a plant that thrives in dry, rocky habitats and requires adequate sunlight. The plant prefers well-drained soil, and it is recommended that the cultivation be done in a warm, dry climate.
When planting this species, it is crucial to dig a hole that is twice the diameter of the plant container and of equal depth. Backfill the hole with soil mixed with compost to ensure the plants get the necessary nutrients.
Watering Needs
Watering this species during the initial period of cultivation is important to allow the plant to establish itself. After the initial period, the plants require very little watering, except during prolonged periods of drought. The optimal way to irrigate this plant is by using a drip system to avoid wetting the foliage.
Fertilization
Eriogonum capistratum Reveal var. muhlickii Reveal doesn't require frequent fertilization. Fertilization should only take place during the spring season using low nitrogen, high phosphorus, and potassium fertilizer.
Pruning
This species doesn't need regular pruning. Deadheading the blooms and removing the seed heads in the fall will help promote the growth of new growth nodes. However, it is recommended that you cut back the plant to 1/3 of its height every three years to promote vigorous growth and prevent woody growth
Propagation of Eriogonum capistratum Reveal var. muhlickii Reveal
Eriogonum capistratum Reveal var. muhlickii Reveal, commonly known as the Muhlick's buckwheat, can be propagated through various methods such as seeds, stem cuttings, and division.
Propagation from Seeds
Seeds can be sown directly in the field after the last frost date in spring. The seeds should be sown at a depth of 1/8 inch and spaced about 12 inches apart. The seeds typically germinate in a few weeks. However, if you want to start the seedlings indoors, you can sow the seeds in pots, trays or flats filled with a well-draining potting mix about 6-8 weeks before the last frost date. Water regularly and keep the soil moist until the seedlings emerge.
Propagation from Stem Cuttings
Stem cuttings can be taken during the summer from healthy, disease-free plants. Use a sharp and sterilized knife to cut a stem of about 4-6 inches long. Remove the leaves from the lower half of the stem and dip the cut end into a rooting hormone. Place the cutting into a well-draining potting mix and water regularly. Keep the plant in a warm and bright location but not in direct sunlight. The cutting should root and form new shoots in about 6-8 weeks.
Propagation from Division
Eriogonum capistratum Reveal var. muhlickii Reveal can also be propagated by division, especially if the plant has grown too large or becomes too crowded. This method involves digging up the clump of plants and dividing the rootball into smaller sections, each containing one or more stems and a portion of roots. Replant the divided sections in well-draining soil and keep them watered until they become established.
Disease Management:
Eriogonum capistratum Reveal var. muhlickii Reveal is generally a disease-resistant plant. However, it may be susceptible to certain diseases, such as:
- Root rot: This disease is caused by waterlogging or overwatering and can lead to wilting and death of the plant. To manage root rot, avoid overwatering the plant and provide proper drainage.
- Powdery mildew: Powdery mildew is a fungal disease that can appear as a white or grey powder on the leaves of the plant. To manage powdery mildew, remove any infected leaves and keep the surrounding area free of debris.
- Rust: Rust is a fungal disease that can cause yellow or brown spots on the leaves of the plant. To manage rust, remove any infected leaves and ensure proper ventilation around the plant.
Pest Management:
Eriogonum capistratum Reveal var. muhlickii Reveal is also generally pest-resistant. However, some pests that may affect the plant are:
- Spider mites: These pests are tiny and can cause yellowing and wilting of the leaves. To manage spider mites, keep the plant well-hydrated and regularly spray it with water to discourage the mites.
- Aphids: Aphids are small, soft-bodied insects that can suck the sap from the plant and cause wilting. To manage aphids, regularly spray the plant with a solution of water and dish soap or neem oil.
