Buckwheat, or common buckwheat, is a plant cultivated for its grain-like seeds and as a cover crop. The name "buckwheat" is used for several other species, such as Fagopyrum tataricum, a domesticated food plant raised in Asia.
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.
Fallopia convolvulus, the black-bindweed or wild buckwheat, is a fast-growing annual flowering plant in the family Polygonaceae native throughout Europe, Asia and northern Africa.
Eriogonum nudum is a perennial shrub of the wild buckwheat genus which is known by the common name naked buckwheat or nude 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 deflexum is a species of wild buckwheat known by the common names flatcrown buckwheat, flat-top buckwheat, and skeletonweed. This plant is native to the southwestern United States and northwestern Mexico, where it is common and grows in a variety of habitats, especially desert scrub. It is somewhat weedy where it is most abundant. This is an annual which varies in size from small patches on the ground to tangled bushes approaching two meters in height; it may be dense or thin and spindly. This is a brown or greenish weedy-looking herb with a many-branched stem. The leaves are located at the base of the plant and are rounded and woolly and one to four centimeters long. Small clusters of flowers appear at intervals along the branches with each flower only one to three millimeters wide and white or pinkish in color.
Eriogonum heermannii is a species of wild buckwheat known by the common name Heermann's buckwheat. It is native to the southwestern United States from California to Utah where it grows on rocky slopes, desert flats, and dry washes.
Eriogonum latifolium is a species of wild buckwheat known by the common names seaside buckwheat and coast buckwheat. This plant is native to the coastline of the western United States from Washington to central California, where it is a common resident of coastal bluffs and scrub.
Eriogonum umbellatum is a species of wild buckwheat known by the common name sulphurflower buckwheat, or simply sulphur flower. It is native to western North America from California to Colorado to central Canada, where it is abundant and found in many habitats, including the sagebrush steppe and alpine areas. It is an extremely variable plant and hard to identify because individuals can look very different from one another. Also, there are many varieties. It may be a perennial herb blooming by summer with stems 10 centimeters tall and two to six clusters of flowers, with a whorl of leaves below the stems, or a sprawling shrub approaching two meters high and wide. The leaves are usually woolly and low on the plant, and the flowers come in many colors from white to bright yellow to purple. Native American groups utilized parts of this plant for a number of medicinal uses.
Eriogonum wrightii is a species of wild buckwheat known by the common names bastardsage and Wright's buckwheat. It is native to the Southwestern United States, California, and northwest Mexico, where it grows in many plant communities, such as chaparral, in rocky habitats from mountains to deserts.
Eriogonum heracleoides is a plant of western North America that has many flowering clusters which are usually cream colored, or off-white. It can usually be found in rocky areas, such as sagebrush deserts and Ponderosa pine forests. Parsnipflower buckwheat is in the genus Eriogonum and the family Polygonaceae, which is a family of plants known as the "knotweed family". It inhabits much of the western part of the United States and southern British Columbia.
Eriogonum angulosum is a species of wild buckwheat known by the common name anglestem buckwheat.
Eriogonum argillosum is a species of wild buckwheat known by the common names clay buckwheat, clay-loving buckwheat, and Coast Range wild buckwheat. It is endemic to California, where it is known only from San Benito and Monterey Counties. It grows on clay substrates, often of serpentine origin. This is an annual herb up to 30 to 60 centimeters tall with a basal patch of oval-shaped, woolly leaves and a naked stem. The top of the stem is occupied by the inflorescence, a cyme with several clusters of tiny white or pink flowers.
Eriogonum brachyanthum is a species of wild buckwheat that is commonly known as shortflower buckwheat. It is native to eastern California and western Nevada, particularly the Mojave Desert region, where it is common to abundant, and even sometimes weedy. It is also known from southern Oregon. The plant grows in sandy habitats such as desert flats and sagebrush. It also grows in pinyon-juniper and montane conifer woodlands. It is an annual herb that grows 30 to 40 centimeters tall. Leaves are located at the base of the stem, woolly, and oval or rounded in shape. The top of the stem is occupied by a branching inflorescence bearing many widely spaced clusters of flowers. Each individual flower is about a millimeter wide and light yellow in color. Flowers bloom from April to November.
Eriogonum breedlovei is a rare species of wild buckwheat known by the common name Paiute buckwheat. It is endemic to the High Sierra Nevada of California, where its two varieties are uncommon members of the flora in granite and limestone rocky high mountain habitat.
Eriogonum eremicola is a rare species of wild buckwheat known by the common names Telescope Peak buckwheat and Wild Rose Canyon buckwheat. It is endemic to Inyo County, California, where it is known from only a few occurrences in the Inyo Mountains and Telescope Peak in Death Valley. It grows in sandy to rocky habitat in the forests and woodlands of these desert mountains. It is an annual herb producing a spreading, glandular, reddish green stem up to about 25 centimeters tall. The rounded, woolly leaves are up to about 2.5 centimeters long and are located at the base of the stem. The scattered inflorescences are small clusters of tiny flowers which are white with reddish stripes, aging to solid red, or sometimes yellow. The plant is under protection in Death Valley National Park.
Eriogonum hoffmannii is a species of wild buckwheat known by the common name Hoffmann's buckwheat. It is endemic to Inyo County, California, where it is found only in the mountains around Death Valley; most of the known populations of the plant are located in Death Valley National Park. The plant grows in the desert scrub on the slopes of the Panamint, Black, and Funeral Mountains.
Eriogonum palmerianum is a species of wild buckwheat known by the common name Palmer's buckwheat. It is native to the Southwestern region of the United States and Great Basin region, where it grows in many types of desert and sagebrush plateau habitat.
