Eriogonum nudum

Zoom To My AddressZoom To California Estimated Plant Range

About Nude Buckwheat (Eriogonum nudum) Eriogonum nudum is a perennial shrub of the wild buckwheat genus which is known by the common name naked buckwheat. The plant is a tall, bare, leafless stem, bifurcating into more stems, each topped with rounded clusters of white or pale pink or yellow flowers growing up to six feet from a basal rosette at the ground, where the flat green leaves are located. The naked stem gives the plant its common name. Naked buckwheat can be found scattered around the west coast of the United States. This species has one of the widest ecological distributions of all of the buckwheats. It can be found at wet coastal sea level locales and the coldest, driest elevations of the Sierra Nevada, as well as many areas in between. The species is not uncommon, but some specific varieties are quite rare.
