Eriogonum is a genus of flowering plants in the buckwheat family, Polygonaceae. It includes around 200 species, commonly known as wild buckwheat. These plants are primarily found in North America, particularly in arid and semi-arid regions, where they thrive in diverse habitats, including deserts and grasslands. Eriogonum species vary in size and form, ranging from low-growing ground covers to taller shrubs. They typically have small, clustered flowers that can be white, yellow, or pink, attracting various pollinators. Many species are drought-tolerant, making them popular choices for xeriscaping and native plant gardens.
