Eriogonum is a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers such as the California buckwheat.
Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.
Eriogonum davidsonii is a species of wild buckwheat known by the common name Davidson's buckwheat. This plant is native to the southwestern United States and northern Baja California. It grows in sandy or gravelly soils, mixed grassland, saltbush, chaparral, sagebrush communities as well as oak and montane conifer woodland. It is a spindly annual herb growing up to 40 centimeters in height. Leaves are fuzzy, basal, and round with wavy or wrinkly margins fuzzy. They are two centimeters wide. The plant is variable in appearance, but is usually erect with thin, naked, neatly branching stems bearing clusters of tiny flowers at widely spaced nodes. Each flower is about 2 millimeters wide, bell-shaped, and can be white, pink or red. Flowering occurs May to September.
