Eriogonum compositum
Arrowleaf buckwheat is such a cool plant that is relatively uncommon in the garden and nursery setting. This low-growing perennial is extremely drought-tolerant and spreads into shrubby mats over time. In late spring and summer, clusters of creamy white tubular flowers balance on tall stalks, resembling puffy clouds that will beckon butterflies and bees to your garden. True to its name, the leaves of this plant are shaped like arrowheads that start out the season bright green, with diagnostic white undersides, and transform into pleasing fall tones in Sept and October.
