General: There are a variety of perennial buckwheats (Eriogonum spp.) often with upright or mounded, finely branched stems, and often with a reddish cast to the plant. The flower parts are in sets of three. There are many species of buckwheats, and as a group, most are difficult to identify. For non-experts in the genus, often it is best to just let them go as "buckwheats."
Perennial buckwheats are common components of vegetation communities in dry, well-drained sandy and gravelly areas on desert flats, bajadas, and moderate slopes in the lower mountains in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub) life zones. |
