Eriogonum compositum

Arrowleaf buckwheat is a low-growing perennial that spreads into low-growing, shrubby mats over time. In late spring and summer, clusters of creamy white tubular flowers plunge into the air, resembling puffy clouds balancing on tall stalks, beckoning butterflies and bees. True to its name, the dark green leaves of this plant are shaped like arrowheads, with diagnostic white undersides.
