Permaculture uses
Buckwheat is an excellent cover crop known for its ability to smother weeds, attract beneficial insects (especially pollinators like bees and hoverflies), and improve soil structure by adding organic matter and phosphorus. It can also be used as green manure. While not a primary food source, the seeds are edible, though less palatable than common buckwheat. It is drought-tolerant, making it suitable for xeriscaping and water-wise gardens. Some Eriogonum species are used for medicinal purposes; however, Eriogonum microthecum use is less documented than that of related species. Important for wildlife, providing food and shelter.
Permapeople description
Eriogonum microthecum, commonly called Slender Buckwheat, is a species of wild buckwheat known from much of western North America. It is variable in appearance, with several varieties that differ in morphology and habitat. It thrives in dry, rocky soils.
Botanical description
Eriogonum microthecum is a variable perennial shrub in the buckwheat family (Polygonaceae). It typically grows to between 1 to 4 feet tall and wide, with a rounded or spreading habit. The leaves are small, alternate, and often have a woolly texture. The flowers are borne in dense, rounded clusters (cymes) at the ends of the branches. Flower color ranges from white to pink, cream, or yellow, and they bloom profusely in the summer. The fruit is a small, dry achene. The plant has a deep taproot, allowing it to thrive in dry, rocky soils. There are several varieties and subspecies, exhibiting variation in leaf shape, flower color, and overall size. This species is generally drought-tolerant and cold-hardy.
Companion planting
Buckwheat, in general, is a good companion plant for many crops due to its ability to attract beneficial insects and suppress weeds. It pairs well with other drought-tolerant species. Avoid planting near plants sensitive to alkaline soils, as buckwheat can slightly raise the pH of the soil. Specific companion planting recommendations for Eriogonum microthecum are not well-documented, but general permaculture principles would apply.
Propagation methods
Propagation is typically done through seeds, which require stratification for optimal germination. Cuttings can also be used, though success rates vary. Root division is possible with established plants.
History and traditions
Several Eriogonum species were traditionally used by Native American tribes for medicinal purposes. Eriogonum microthecum was likely used for similar purposes, although specific documented uses may be limited compared to other more common species within the genus. The plant may have been used for treating skin ailments, digestive issues, or as a general tonic. Buckwheats have cultural significance in some communities due to their nutritional and environmental benefits. Historically, some tribes also consumed the seeds after processing.
